compact bone. yah buddy!
Compact bone is the outer region of all the bones in your body.There are two basic parts of each of your bones:There is an outer hard layer of bone called either compact bone or cortical bone. this layer is much more dense.There is an inner layer of bone called either cancellous bone or trabecular bone. This is a softer bone and contains bone marrow and much more blood vessels than the cortical (compact) bone.
Compact bone appears as a dense, solid tissue with few gaps or spaces. It is made up of concentric circles of bone tissue called lamellae, surrounding vascular canals known as Haversian canals which contain blood vessels and nerves. Compact bone provides strength and support to the skeleton.
Compact bone.
Compact bone provides strength and support for the body by forming a hard protective layer around the bone marrow. It also helps in the storage of minerals such as calcium and phosphorus, which are important for various bodily functions.
Endosteum is a thin membrane that lines the inner surface of bones and contains bone-forming cells, while compact bone is a dense and hard outer layer of bone that provides strength and support. Compact bone is composed of tightly packed osteons, which are the structural units of bone tissue, while endosteum is involved in bone remodeling and repair processes.
bone marrow is in the center of the bone shaft
Actually the compact bone isn't spongy at all, the compact bone is a tough layer making the bone neither too rigid or too brittle. So the compact bone is not spongy. Spongy bone, like its name is spongy.
Spongy bone has holes in it that make it strong, but compact bone doesn't have any holes in it.
The compact bone surrounds the spongy bone and provides structure for the body.
The membrane that covers compact bone is called the periosteum. It contains blood vessels, nerves, and osteoblasts (bone-forming cells) that help with bone growth, repair, and nourishment. The periosteum also plays a role in bone regeneration and acts as a protective barrier for the underlying bone tissue.
The weight of compact bone can vary depending on factors such as age, gender, and individual differences. On average, compact bone tissue comprises about 80% of the weight of the human skeleton. The weight of a compact bone can range from a few grams to several kilograms.
