| Description: Bone contains 4 types of cells: Osteoprogenitor cells (bone stem cells able to differentiate into the other types of cells) Osteoblasts (bone-building cells that secrete matrix) Osteocytes (mature bone cells) Osteoclasts (remodel bones and cause them to release calcium) A long bone consists of several parts: Diaphysis (bone shaft) 2 epiphyses (both ends of the bone at the joints) 2 metaphyses (region between diaphysis and epiphysis) Articular cartilage covering both epiphyses Periosteum (connective tissue surrounding the diaphysis) Medullary cavity (hollow space within diaphysis) Endosteum (thin membrane lining the medulary cavity) Picture Stats: Views: 168 Filesize: 1018.31kB Height: 714 Width: 1350 Source: https://biology-forums.com/index.php?action=gallery;sa=view;id=40359 |
