Section Of Bone
Bones at a glance.
Section of bone. This section will examine the gross anatomy of bone first and then move on to its histology. Bone rigid body tissue consisting of cells embedded in an abundant hard intercellular material. The remainder is cancellous bone which has a spongelike appearance with numerous large spaces and is found in the.
Learn more about the composition and function of bone. Osteoblasts osteoclasts osteocytes and osteoprogenitor cells. For example to read this diagram literally since the cartilage can be seen inside the cutaway section of bone it incorrectly indicates that the cartilage in fact goes through the bone structure rather than just being found around the bone end.
Red marrow fills the spaces in the spongy bone. A typical long bone showing gross anatomical features. The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions.
Osteoblasts synthesize and secrete the organic part and inorganic part of the extracellular matrix of bone tissue and collagen fibers. Cancellous bone also called trabecular or spongy bone is the internal tissue of the skeletal bone and is an open cell porous network. The bones of the legs are those that make up the thigh the lower half of the legs and the feet.
Cell types in bones. The wider section at each end of the bone is called the epiphysis plural epiphyses which is filled internally with spongy bone another type of osseous tissue. Red bone marrow fills the spaces between the spongy bone in some long bones.
Its two principle components are collagen and calcium phosphate. Cancellous bone has a higher surface area to volume ratio than cortical bone and it is less dense this makes it weaker and more flexible. Bone consists of four types of cells.
