HLSC 1200U Lecture Notes - Lecture 8: Flat Bone, Endosteum, Diaphysis
Document Summary
Support: they contribute to the alignment, shape, and positioning of body parts. Protection: skull, ribcage, and vertebrae, they form bony "boxes"" that protect more delicate tissue. The skull protects the central nervous system, the ribcage protects the heart and lungs, and the vertebrae protects heart and lungs. Movement: bones allow muscles to pull on them to make movement. Mineral storage: bones serve as a major mineral storage reservoir (phosphorus and calcium) This formation of blood cells occurs in myeloid tissue found in red bone marrow. The red bone marrow is found in the spongy bone. The formation of both red blood cells and white blood cells occurs. Humerus: cylindrical bone located in the upper arm. Carpal: short, boxlike bone located in the hand. Sternum: considered a flat bone, broad and sheetlike. Patella: sesamoid bone (shaped like sesame seeds) Articular cartilage (external): found where one bone meets another bone.
