Document Summary
Axial skeleton: forms the longitudinal axis of the body. Includes the skull and associated bones, the thoracic cage, the vertebral column, and various supplemental cartilage. Typically 80 bones in the axial skeleton. Provides a framework that supports and protects the brain, the spinal cord, and the organs in the body cavities of the trunk. Provides an extensive surface area for the attachment of muscles that. Adjust the positions of the head, neck, and trunk. Stabilize or positions parts of the appendicular skeleton that supports the limbs. Joints have limited movement, but are very strong and heavily reinforced by ligaments. 7 additional bones are associated with the skull. Six auditory ossicles - located within the temporal bones. Hyoid bone - connected to the inferior surfaces of the temporal bones by a pair of ligaments. Protect and support the entrances to the digestive and respiratory tracts. Provide areas for the attachment of muscles that control facial expressions and assist in manipulating food.
