ANATOMY

Detailed explanation-1: -Compact bone (also known as cortical bone) forms the hard, dense outer layer of bones throughout the human body. Compact bone functions primarily to provide strength and protection to bones, and it is one of two types of bone tissue. The other type of bone tissue is known as spongy bone.

Detailed explanation-2: -The outer layer of a bone is called compact or cortical bone. This layer is hard and particularly solid, and it makes sure that our bones can withstand daily physical strains. The outer layer has a thin coating called the periosteum.

Detailed explanation-3: -Compact bone is the solid, hard outside part of the bone. It looks like ivory and is extremely strong. Holes and channels run through it, carrying blood vessels and nerves. Cancellous (KAN-suh-lus) bone, which looks like a sponge, is inside compact bone.

Detailed explanation-4: -compact bone, also called cortical bone, dense bone in which the bony matrix is solidly filled with organic ground substance and inorganic salts, leaving only tiny spaces (lacunae) that contain the osteocytes, or bone cells.

Detailed explanation-5: -Compact bone is formed from a number of osteons, which are circular units of bone material and blood vessels. These units allow compact bone to remain hard and compact while still receiving nutrients from the body and disposing of waste through the same channels.
