KIN 270 Chapter Notes - Chapter 6: Bone, Bone Marrow, Medullary Cavity
Document Summary
Module 4: the gross structure of all bones consist of compact bone sandwiching spongy. Fossa: shallow, basinlike depression in a bone, often serving as an articular surface. A narrow, slitlike opening in a bone is referred to as a fissure. Medullary cavity: hollow space in the shaft of a long bone. The cells that maintain mature compact bone matrix is osteocytes. Epiphysis: expanded portion of the long bone at its ends. Head: bony expansion carried on a narrow neck. Trochanter: very large, blunt, irregularly shaped process. Foramen: round or oval opening through a bone. Spongy bone is where red bone marrow is in an adult. Canaliculi: tiny canals that connect the central canal of an osteon to the osteocytes. Osteocytes maintain contain allowing them to communicate and permitting nutrients and wastes to be relayed from one osteocyte to the next through canaliculi. Collagen fibers do not provide for bone hardness.
