Cancellous bone is a spongy type of bone inside the cortical bone. It’s not as dense as the outer cortical bone. Some bones have a lot of it, and some bones have less. A broken bone may heal faster if it has more cancellous bone inside. Bone Marrow. Your bone marrow is deep inside your bones – inside the middle of the cortical and spongy bones.
Two types of bone found in the body—cortical and trabecular. Cortical bone is dense and compact. It forms the outer layer of the bone. Trabecular bone makes up the inner layer of the bone and has a spongy, honeycomb-like structure. NIH - National Institute of Arthritis and Musculoskeletal and Skin Diseases
The periosteum consists of dense irregular connective tissue.It is divided into an outer "fibrous layer" and inner "cambium layer" (or "osteogenic layer"). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts.These osteoblasts are responsible for increasing the width of a long bone and the overall size...
n the layer of connective tissue that varies considerably in thickness in the different areas of bone. It consists of two layers: an outer layer, which is rich in blood vessels and nerves and shows a dense arrangement of collagenous fibers, and an inner layer, the cambium, in which the fibers are loosely arranged, the cells numerous, and the blood vessels relatively sparse.
The other three layers are the compact bone, cancellous bone and bone marrow. Compact bone is a smooth and hard bone layer, while cancellous bone is a spongy layer found inside the compact bone. Although cancellous bone is strong, it is more porous than compact bone. The innermost bone layer consists of bone marrow. The main function of bone ...
The top layer is called periosteum, which is a slippery thin tissue that covers the areas where tendons (the things that connect bone to muscle) and ligaments (the things that connect bone to bone).
Compact Bone is the tough outer layer of bone while spongy bone isthe porous bone where the red and yellow marrow is. Spongy is softer bone, with holes in it. It is found inside thebone.
- honeycomb inner layer (spongy bone) - open spaces between trabeculae are filled with red or yellow bone marrow. general structure of long bones - shaft - bone ends - membranes. periosteum - shiny, white, double-layered bone membrane - covers external surface of bone except joint surfaces
Periosteum, dense fibrous membrane covering the surfaces of bones, consisting of an outer fibrous layer and an inner cellular layer (cambium).The outer layer is composed mostly of collagen and contains nerve fibres that cause pain when the tissue is damaged. It also contains many blood vessels, branches of which penetrate the bone to supply the osteocytes, or bone cells.
