BIOL-3160 Lecture Notes - Lecture 6: Medullary Cavity, Sesamoid Bone, Dermal Bone
Document Summary
Maintain matrix and tissues overall health and viability. Many thick collagen fibers for tensile compressional forces. Interstitial and appositional growth occur simultaneously during embryonic. Interstitial growth declines rapidly as cartilage matures with later growth mainly. Skeletal muscle pulls on skeleton, using bones as levers. Classified according to their shape of place of development. Elongated shaft (diaphysis) and two distinct ends (epiphysis) Thin, flattened, usually curved underlying soft tissues. Provide extensive sa for muscle attachment and protection for. Isolates/protects bone from surrounding structures, anchors blood vessels. Contains osteoprogenitor cells, osteoblasts, osteoclasts which are important for bone growth, repair and remodeling. Appears disorganized but trabeculae align along lines of stress. Trabeculae are only few cell layers thick. Skeleton growth determines size and proportions of body. Process of replacing other tissues with bone. Dermal ossification is described as the process by which bone develops within a. Occurs at ep - region of hyaline cartilage.
