Document Summary

Includes bones, cartilage, joints, and ligaments: 206 bones in axial and appendicular skeletons, mainly connective tissue, bone and cartilage predominant types. Functions: support (is connective tissue, protection (flat bones provide protection for internal organs, movement (essential for movement but require muscles as well. This allows for skeletal system repair : bone cells, osteoclasts. Large, specialized cells in endosteum: destroy or reabsorb bone, phagocytize bone matrix- separates minerals from organic material and gives us. Secrete lysosomal enzymes and metabolic acids: cells of osseous tissue (2) Ca when needed or helps lighten the bone if necessary: osteoclasts develop in bone marrow by fusion of 3-50 stem cells, reside in pits that they ate into the bone, bone matrix, organic material provide tensile strength. Fibers mostly collagen: resist bending, twisting, stretching. Include mineral salts - primarily ca and p: bone properties, combination of organic & inorganic materials.
