Bones of the skull and vertebral column.

Includes appendages and their attachments to axial skeleton.bones of the upper and lower extremities of the body

The appendicular skeleton consists of the bones of the upper and lower extremities of the body, and includes appendages and their attachments to the axial skeleton. It does not include bones of the skull and vertebral column, muscles and tendons in the body, or organs in the abdominal cavity.

Explanation

4. What does the axial skeleton consist of?

Bones of the hands and feet (metacarpals, metatarsals)

Bones of the arms and legs (humerus, femur)

Bones of the head, neck and torso (head, vertebrae, ribs and the sternum)

Teeth and jaw bones

The axial skeleton includes bones of the head, neck, and torso, such as the skull, vertebrae, ribs, and sternum. It provides support and protects vital organs like the brain and heart.
