Which bones are in the axial and appendicular skeleton?

What are the 22 bones of the skull?

The human skull is generally considered to consist of twenty-two bones—eight cranial bones and fourteen facial skeleton bones. In the neurocranium these are the occipital bone, two temporal bones, two parietal bones, the sphenoid, ethmoid and frontal bones.

What is the ratio of axial to appendicular bones in the human body?

The function of the Axial skeleton The intervertebral disc(which lies between the adjacent vertebrae in the spine) is a classic example of a joint within the Axial skeleton in that it is very strong and will only permit limited movement. Of the 206 bones in the human body 126 of these make up the appendicular skeleton.

What does the axial skeleton do?

The function of the axial skeleton is to provide support and protection for the brain, the spinal cord, and the organs in the ventral body cavity. It provides a surface for the attachment of muscles that move the head, neck, and trunk, performs respiratory movements, and stabilizes parts of the appendicular skeleton.

Which bone is a part of the axial skeleton?

The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.

How do we classify bones?

Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

What are the 3 main parts of the axial skeleton?

The axial skeleton is the part of the skeleton that consists of the bones of the head and trunk of a vertebrate animal, including humans. The primary divisions of the skeleton system are the head, thorax, and vertebral column. The human cranium supports the structures of the face and forms the brain cavity.
