Document Summary

Biol 1410: anatomy of the human body - lecture 15: skeletal system. 2 layers of connective tissue: outer = dense regular ii. inner = osteoblasts + osteoclasts lines medullary cavity and canals articular cartilage hyaline prevents friction between bones, histology: bone & cartilage. Consists of: a) cells b) osteoblasts osteocytes osteoclasts matrix ground substance. Haversian canal and the medullary cavity b) spongy bone structure: o o is not made up of osteons instead, are made up of trabeculae. Irregularly arranged lamellae spaces contain bone marrow o. Cartilage (ct) hyaline cartilage structure: o a) b) chondrocytes in lacunae matrix: ground substance made of chondroitin sulphate and hyaluronic acid, collagen fibers, water non-vascular c, articulations / joints. 2 classes: structural + functional: structural classification. Types of structural joints: fibrous no joint cavity fibrous connective tissue e. g. sutures in skull, periodontal ligaments, cartilaginous no joint cavity cartilage e. g. pubic symphysis, costal cartilages.
