ANT205H5 Chapter Notes - Chapter 2: Haversian Canal, Osteoid, Osteology
Document Summary
Analyses depend on knowledge of: osteology study of bones, odontology study of teeth. Skeleton system of mineralized connective tissue serving as a framework for support and attachment for muscles, tendons, and ligaments: controlled by muscles for body movement, protects organs, produce blood cells, store minerals and fat. Teeth are mineralized structures that function masticate (chew or break down) food, and speak. Need to know variations to differentiate between skeletons of different groups + recognize alterations (e. g. trauma, damage, pathological conditions) Mature bones are dense and cannot be nourished by surface blood vessels. Histology study of the microscopic structures of tissue. Medullary cavity hollow inner part of bone shafts: contains primarily red marrow during growth then replaced by yellow. Periosteum thin tough tissue layer covering external surface of all bones endosteum membrane covering inner surface: both help nourish bone + repair trauma. Osteogenesis deposition of bone matrix on pre-existing surface to grow.
