Honors A & P - Major Bones and Major Bone Features of the Human Skeleton
Using your textbook, the following tutorial (http://www.gwc.maricopa.edu/class/bio201/skeleton.htm), as well as the skeleton /
skulls provided identify the location of each of the bones of the axial skeleton as well as the prominent features of those bones
that are listed with each bone. Write down a descriptive phrase or statement that will allow you to identify or recognize the
bone or feature of bone listed.
Axial Skeleton: The 80 bones that form the upright axis of the body; the skull (including the ossicles), hyoid bone,
vertebral column, sternum and ribs.
Cranium: 8 bones that form the floor and case of the skull that protects the brain, some bones also contain
paranasal sinuses that are air filled cavities connected by passageways to the nasal cavity. They reduce the weight
of the skull and act as resonance chambers it increase the intensity of one’s voice.

Axial Skeleton: The 80 bones that form the upright axis of the body; the skull (including the ossicles), hyoid bone,
vertebral column, sternum and ribs.
Vertebral Column: 26 bones that form the flexible, segmented, s-shaped axis that enclose and protect the spinal
cord.
