In this article, we will “learn all 206 bones in the body-The skeletal system”. There are 206 bones in the human body. They are divided into two types: axial and appendicular. The axial skeleton is made up of the bones in the head, neck, and trunk. The appendicular skeleton is made up of the bones in the arms and legs. I hope after reading Learn all 206 bones in the body article will clear all of your doubts and you will be able to teach someone.
What is the Mission of the article “Learn all 206 bones in the body”?
Our mission is that the student who want to learn about 206 bones, to make assignments or to learn about skeleton can get all information about bones in this 206 bones article
Firstly, we will learn about Axial Skeleton:
Axial Skeleton:
The axial skeleton is the central axis of the body. It contains the bones of the head, neck, and trunk. The axial skeleton provides support and protection for these organs. There are 80 bones in Axial Skeleton which are divided into two structures i.e. Skull and Torso. Skull has 28 bones in which 6 bones lie separately and remaining 22 bones lie as a pair i.e. pair of 11 bones. Torso has 52 bones in which 28 bones lie separately and remaining 24 bones lie as a pair i.e. pair of 12 bones. The names of them are discussed as follows:-

Now we will learn about Skull bones (28) one by one in detail.
Skull Bones (28):
The skull bones are a part of the axial skeleton. The axial skeleton is responsible for the support of the head and trunk. As we know skull has 28 bones which are discussed below with names. There are 11 paired bones which are as follows:-
Paired Bones (11 x 2 = 22):
1. Nasal Bone:
The nasal bone is a small, thin, and curved bone in the human skull. It is located in the middle of the face, and forms the bridge of the nose. The nasal bone helps to support the structure of the nose, and is one of the bones that is used to determine the age of a person from their skull.
2. Lacrimal Bone:
The lacrimal bone is a small, thin bone that is located in the upper part of the human eye socket. It is responsible for producing tears, which keep the eye moist and lubricated. The lacrimal bone is attached to the eyelid and the edge of the orbit (eye socket). The lacrimal bone is a very small and delicate bone, and is easily damaged. It can be fractured by a direct hit to the eye, or by a fall. A fracture of the lacrimal bone can cause severe pain, swelling, and blurred vision.
3. Inferior Bone:
There are three bones in the human body that are considered inferior: the clavicle, the fibula, and the tibia. The clavicle is the only bone in the human body that is not connected to another bone. It is located in the upper chest and connects the shoulder to the arm. The fibula and tibia are located in the lower leg. The fibula is on the outside of the leg, and the tibia is on the inside of the leg.
4. Nasal Concha Maxillary Bone:
The nasal concha maxillary bone is a small, curved, and spongy bone in the human body. It is located in the medial wall of the orbit, and is part of the orbitofrontal bone. The nasal concha maxillary bone helps to form the roof and lateral wall of the nasal cavity, and also helps to support the medial wall of the orbit.
5. Zygomatic Bone:
The zygomatic bone, also known as the cheekbone, is a bone located in the human skull. It is the bone that makes up the prominence of the cheeks. The zygomatic bone is responsible for facial expressions and is also involved in mastication (chewing).
6. Temporal Bone:
The temporal bone is a bone in the human skull. It is situated at the side of the head, beneath the parietal bone, and in front of the sphenoid bone. The temporal bone consists of a body, two squamous plates (the squamous temporal bone), two petrous pyramids, and four bones that form the ear (the malleus, incus, stapes, and tympanic part of the temporal bone).
7. Palatine Bone:
The palatine bone is a small, thin bone in the human body that is located in the roof of the mouth. It is one of the bones that make up the skull, and it is responsible for forming the hard palate. The palatine bone also helps to support the teeth and form the nasal cavity.
8. Parietal Bone:
The parietal bone is one of the two bones that make up the human skull. It is located at the top and back of the skull, and is responsible for protecting the brain. The parietal bone is also responsible for the formation of the roof of the mouth and part of the palate.
9. Malleus Bone:
The Malleus bone is one of the smallest bones in the human body. It is located in the middle ear, and is responsible for transmitting sound vibrations to the inner ear. The Malleus bone is attached to the tympanic membrane, which is the thin membrane that separates the outer and inner ears.
10. Incus Bone:
The incus is one of three tiny bones in the human ear that work together to transmit sound vibrations from the eardrum to the cochlea. The incus is the smallest and most medial of the three bones. It is also the only one that is not connected to another bone; it is attached to the malleus by a ligament.
11. Stapes Bone:
The stapes bone (also known as the stirrup bone) is one of the smallest bones in the human body. It is located in the middle ear, and helps to transmit sound vibrations from the eardrum to the inner ear. The stapes bone is attached to the oval window, which separates the middle ear and inner ear. The stapes bone is a very important part of the human auditory system. It plays a key role in hearing sounds, and helps to amplify sound vibrations. Damage to the stapes bone can result in hearing loss or impairment.
One only Bone:
1. Frontal bone:
The frontal bone is located in the human skull and is responsible for protecting the brain. It is the largest and most anterior bone in the skull. The frontal bone is also responsible for shaping the forehead and forming the roof of the eye sockets. The frontal bone is composed of two parts: the squamous part and the orbital part. The squamous part is thin and flat, while the orbital part is thicker and more curved. The two parts are connected by a suture.
2. Ethmoid bone:
The ethmoid bone is a small, irregularly shaped bone located in the middle of the face between the eyes. It is one of the bones that make up the cranium, and it helps to protect the brain. The ethmoid bone is also responsible for housing the sinuses, which help to humidify and warm air as it passes through the nasal cavity.
3. Vomer bone:
The vomer (from Latin vomer, meaning “plowshare”) is a thin, flat, triangular bone in the nasal septum of the human skull. It separates the nasal cavity into two fossae. The vomer is attached to the premaxilla and maxilla bones in the front of the skull, and to the ethmoid and sphenoid bones at the rear.
4. Sphenoid bone:
The sphenoid bone is a unique and complex bone in the human body. It is one of the bones in the skull, and it has a variety of important functions. The sphenoid bone is responsible for housing the pituitary gland, and it also plays a role in facial development. This bone is also important for cranial nerve function. There are twelve cranial nerves, and the sphenoid bone houses six of them. These nerves control many important functions, such as vision, hearing, and speech.
5. Mandible bone:
The mandible is the lower jawbone in the human body. It is a curved bone that connects to the skull at the temporal bones and to the upper jaw at the maxilla. The mandible houses the teeth and supports the lips and cheeks. It also helps to form the floor of the mouth and plays a role in mastication, or chewing.
6. Occipital bone:
The occipital bone is a triangular-shaped bone located at the back of the head. It is the largest and heaviest bone in the human skull. The occipital bone protects the brain and spinal cord, and helps to hold the head upright. The occipital bone is divided into two parts: the body and the condyle. The body of the occipital bone is curved and sits on top of the spinal cord. The condyle is a knob-like projection that articulates with the first cervical vertebrae.
Awesome! I hope you have cleared all of your concepts through the article. If your answer is no then first read out again about skill bones so we proceed. It is important to clear previous concepts for further reading. Now, we will discuss about Torso Bones.
Torso Bones (52):
The torso is connected to the head and limbs, which are all connected to the spine. It is mentioned earlier that Torso has 52 bones. Before reading towards the Torso bones details, first we must have to discuss about Rib.
What is Rib?
The rib is a bone in the human body that is located on the left and right side of the thoracic cavity. It is the longest and most curved bone in the human body. The rib cage protects the heart, lungs, and other vital organs.
What is the rib cage?
The rib cage is a bony structure that surrounds the thoracic cavity and protects the lungs, heart, and other organs in the chest. The rib cage is composed of 12 pairs of ribs. The first seven pairs of ribs are attached to the sternum (breastbone) in the front of the body. The eighth, ninth, and tenth pairs of ribs are attached to the vertebrae in the back of the body. The eleventh and twelfth pairs of ribs are free-floating and not attached to any other bones.
Paired Bones (12 x 2 = 24):
1. Rib 1:
The first rib is the most superior rib and is also the thinnest. It is located at the top of the ribcage, and is the first rib to articulate with the clavicle. The first rib is also the shortest rib, and is generally not visible in an X-ray.
2. Rib 2
The 2nd rib is the second rib in the human body. It is located on the right side of the chest and is the first rib to articulate with the sternum. The 2nd rib is also responsible for articulating with the first thoracic vertebra.
3. Rib 3
The 3rd rib is the most commonly fractured rib in the human body. It is located on the right side of the ribcage and is often injured in car accidents and from contact sports. The 3rd rib can be identified by its location, and by the fact that it is the only rib that has costal cartilage attached to it.
4. Rib 4
The fourth rib is located on the right side of the body, and is the fourth rib counting from the top. It is a short, curved bone that articulates with the fifth rib in the front and the seventh rib in the back. The fourth rib is one of the floating ribs, meaning that it is not attached to the sternum.
5. Rib 5
The 5th rib is located in the front of the human body, on the left side. It is the shortest and thinnest rib in the ribcage. The 5th rib attaches to the breastbone and the first thoracic vertebrae.
6. Rib 6
The 6th rib is located in the human body between the 5th and 7th ribs. It is a small, triangular bone that is attached to the spine and helps to protect the lungs and heart. The 6th rib is not used for any specific purpose, but it can be helpful in identifying certain medical conditions. If you are experiencing pain in the area of the 6th rib, you should consult a doctor to determine the cause. Pain in this area can be a sign of a number of different medical conditions, including lung cancer, heart disease, and pneumonia.
7. Rib 7
The 7th rib is located on the right side of the body and is the last rib in the thoracic region. It is a short, thin rib that does not have a lot of muscle attached to it. The 7th rib has a few important functions, including protecting the organs in the chest cavity and helping with breathing. The 7th rib is also known as the floating rib because it is not attached to any other bones in the body. This makes it more susceptible to injury than other ribs. If the 7th rib is injured, it can cause pain and difficulty breathing.
8. Rib 8 (False)
The 8th rib is a false rib. It is not one of the true ribs, which are the first seven pairs of ribs that attach to the sternum in the front of the chest. The false ribs are the next five pairs of ribs, and the 8th rib is the last one in this group.
9. Rib 9 (False)
The 9th rib is a false rib. It is not one of the 12 ribs that make up the thoracic cage. The 9th rib is an anomaly, and is found in less than 1% of the population.
10. Rib 10 (False)
The 10th rib is a false rib. It’s not really a rib at all, but rather the last part of the spine. It’s called the “false” rib because it’s not one of the true ribs that attach to the sternum. The 10th rib is actually a continuation of the vertebrae in the spine.
11. Rib 11 (Floating)
The eleventh rib (floating rib) is the last true rib and the shortest rib. It is so named because it is not attached to the sternum like the other ribs. The floating rib is found on the right side of the body and is attached to the vertebrae.
12. Rib 12 (Floating)
The 12th rib (floating rib) is the last rib in the human body. It is not attached to the sternum or the spine, and therefore moves independently. The 12th rib is found on the right side of the body, and is shorter and thinner than the other ribs. The 12th rib has no known function and is often removed during surgery. Some people believe that the 12th rib is responsible for extra-sensory perception or psychic ability, but there is no scientific evidence to support this claim.

Appendicular Skeleton (126)
Upper Extremity of Appendicular Skeleton in the human body:
The upper extremity is the part of the human body that includes the shoulder, arm, and hand. The upper extremity is responsible for performing many tasks, including grasping, lifting, and throwing. The shoulder is a ball-and-socket joint that allows a wide range of motion in the arm. The arm is made up of three bones: the humerus, the radius, and the ulna. The hand has five metacarpal bones and fourteen phalanges.
Upper Extremity (32 x 2 = 64):
1. Scapula
The scapula bone is one of the most distinctive bones in the human body. It is located in the upper extremity, and plays a vital role in the movement of the arm. The scapula is triangular in shape, and has a ridge along its length called the spine. The spine divides the scapula into two sections: the medial border and the lateral border. The medial border is shorter and curved, while the lateral border is longer and straight. The surface of the scapula is covered with muscle tissue, which helps to move the arm.
2. Clavicle

Have you really reached here? That’s awesome! You have completed information about almost 144 bones through this article . Now we lead towards the lower extremity of the Appendicular Skeleton and discuss in detail about it one by one.
Lower Extremity of Appendicular Skeleton in the human body:
The lower extremity is a complex system of muscles, bones, and joints that allow us to move around. It starts with the hip, which is the largest and strongest bone in the body. The femur attaches to the hip and runs down the thigh. The knee is a hinge joint that connects the femur and tibia, and allows for movement in the front to back and side to side planes. The ankle is a hinge joint that connects the tibia and fibula, and allows for movement in the up and down plane.
Lower Extremity (31 x 2 = 62):
1. Hip (Ilium, Ischium, Pubis)
The Hip (Ilium, Ischium, Pubis) bone is located in the lower extremity of the human body. The hip joint is a ball and socket joint. The femur (thighbone) is the ball and the acetabulum (a socket in the pelvis) is the socket. The joint is not just a simple connection between two bones but is held together by muscles, ligaments, and tendons. The hip joint is a weight-bearing joint. It helps us walk, run, and jump.
2. Femur
The femur is the longest and strongest bone in the human body. It is the uppermost bone in the leg, and attaches to the hip bone in the pelvis. The femur is responsible for bearing the weight of the body and transferring that weight to the ground. The femur is a multipurpose bone. It is responsible for both movement and stability. The femur has a large range of motion, which allows us to walk, run, and jump. The femur also provides stability for the knee joint.
3. Patella
The patella, also known as the kneecap, is a small bone in the lower extremity of the human body. It is located in front of the femur and articulates with the tibia. The patella helps to protect the knee joint and provides leverage for muscle contraction.
4. Tibia
The tibia is the larger and stronger of the two bones of the lower leg, the other being the fibula. It extends from just below the knee to the ankle. The tibia is a weight-bearing bone and plays an important role in both standing and walking.
5. Fibula
The fibula is a long, thin bone in the lower leg. It is situated between the tibia, which is the larger and stronger bone in the lower leg, and the ankle bones. The fibula has two main functions: it supports the weight of the body and helps to form the ankle joint. It also plays a role in movement of the foot and ankle.
6. Talus
The talus is one of the tarsal bones of the foot. It is a small, irregularly shaped bone that articulates with the navicular bone, calcaneus, and first metatarsal bone. The talus lies just in front of the ankle and helps to form the ankle joint.
