Document Summary
Components of the skeletal system: bones, cartilage, ligaments, connective tissues, each bone is an organ. Skeletal system functions: support, protection, mineral storage, triglyceride (fat) storage (yellow marrow, red and white blood cell formation called hemopoiesis (red marrow) e. i. Children have more red marrow than adults: leverage (assistance in movement) Divisions of the skeletal system: axial a. i. Attached to axial skeletal (legs, arms, joints, etc) b. ii. Sesame seed shape, improve mechanical advantage of muscles e. ii. Bones within skull, in between big bones of the skull f. ii. Flat bone anatomy: flat bone outside, spongey bone in the middle, periosteum lines outer surface. Periosteum: connective tissue membrane covering external surface of bone, continuous with tendons, connective tissue of joints b. i. Continuous with capsule at the end of the bone: attached to bone matrix via perforating fibers, 2 layers d. i. Outer fiberous later (protection of bone tissue) d. ii. Canals of compact bone: contains osteogenic cells important for bone growth and remodeling.
