Document Summary

Includes bones, cartilage, joints, and ligaments: 206 bones in axial and appendicular skeletons, mainly connective tissue, bone and cartilage predominant types. Functions of the skeletal system: protection, support, movement, red blood cell production, found in flat bones (spongy bones, storage, calcium, needed for muscle contraction, needed in brain. Chemical composition: organic materials, osteoid, cell, osteoblasts (build bones, example: builds bone back after a fracture, osteoclasts (break down bone, osteo(cid:272)(cid:455)tes (cid:894)osteo(cid:271)last that is(cid:374)"t a(cid:272)ti(cid:448)el(cid:455) (cid:271)uildi(cid:374)g (cid:271)o(cid:374)e(cid:895) If there were more osteoblasts than osteoclasts, the bone would become larger and heavier.
