HSC 4551 Lecture Notes - Lecture 10: Complex Differential Form, Probenecid, Dense Irregular Connective Tissue
Document Summary
Provides support, protection, movement, electrolyte balance, acid-base balance, and blood formation for the body. Connective tissue that is hardened by the deposition of calcium phosphate and other minerals. Long bones have a dense outer shell called compact bone. Blood is formed in the marrow cavity within bone. Spongy bone is located at the end of long bones and is more loosely organized. Epiphyseal plates are where the growth in length of long bone occurrs. Bones are covered by the periosteum, which is a tough, fibrous layer of collagen. Provides a continuation to tendons and muscles. Bone resorption occurs when osteoclasts digest old bone, and lay down new bone until the resorbed bone is completely replaced and the osteoblasts become mature bone cells called osteocytes. Causes bones to become weak, brittle, and easily susceptible to fracture due to decreasing bone density. Related fractures most commonly occur in the hip, wrist, or spine.
