Function of mastoid process

Attachment for head muscles; contains air cells that regulate ear pressure; protect the temporal bone

Function of external acoustic process (ear canal)

Channels sound to the eardrum; uses earwax to trap foreign objects

frontal:parietal

What does the squamous suture separate

temporal:parietal

parietal

Function of diaphysis

central part of bone - supports muscles (attachments); stores minerals like calcium and fat

Function of epiphysis

Ends of a long bone; forms joints w/ adjacent bones; covered w/ cartilage: location of spongy bone and red bone marrow

Function of articular cartilage

Connective tissue - covers epiphysis; decrease friction and absorb energy

Function of periosteum

Layer of vascular tissue that covers the bone - supplies blood and allows bone to grow and heal

Function of compact bone

Dense outer layer=strength and protection
