ANTHROP 3PP3 Lecture Notes - Lecture 1: Hydroxylapatite, Collagen, Central Canal
Document Summary
Bones can be affected by internal, and external factors. Mineral reservoirs (eg. calcium) production of red blood cells. o o. Typically found in the ends of long bones. Made of small rods and plates called trabeculae. Contains blood supply which brings nutients to the bone. Haversian canal: vertical cannals which contain blood supply. Volkmann"s canal: horizontal canals which connect haversian canals. Lamellae: concentric collagen fibers surrounding a central canal. Canaliculi - tiny channels that radiate from haversian canal, (haversian canal) containing blood vessels and nerves. connecting lacunae in adjacent lamellae. The holes between the trabecular bone have marrow in them. **image of femur diagram**: periosteum: fibrous membrane that covers living bone not covered by cartilage. Used to protect and nourish bone, helps to fix fracture and assists with bone growth. bleeding. If periosteum is loosened, it can cause issues with the bone. Significant: endosteum: membrane that lines the inner surface of living bone.
