Osteoprogenitor cells - Study guides, Class notes & Summaries

Yellow Bone Marrow - ️️found in medullary cavity and in spongy bone of some bones; is yellow because it (adipose tissue) stores fat Osteocytes - ️️•mature bone cells that maintain the bone matrix •live in lacunae between layers (lamellae) of matrix •connect by cytoplasmic extensions through canaliculi in lamellae •Do not divide •Two major functions: 1. To maintain protein and mineral content of matrix 2. To help repair damaged bone Sesamoid Bones - ️️bones that are...
