Bone tissue may be classified into two types: compact and spongy. As implied by their names, the density, or how firmly the tissue is packed together, varies between the two kinds. There are three different types of cells that contribute to the maintenance of bone homeostasis.
The two layers of compact bone, as well as the inner spongy bone, all work together to protect the organs on the inside of the body.Even if the exterior layer of a cranial bone cracks, the brain is still protected by the inner layer of the bone, which remains intact.A flat bone’s anatomy is illustrated in Figure 6.3.3: An illustration of a flat bone in cross-section illustrates the spongy bone (diplo) that is covered on either side by a spongy bone.
What are the layers of bone called?
- The diaphysis is the long central shaft of the spine.
- The epiphysis is responsible for the formation of the bigger rounded ends of long bones.
- The metaphysis is the space between the diaphysis and the epiphysis at both ends of the bone.
- Epiphyseal Plates: These cartilage plates, also known as growth plates, are responsible for allowing the long bones to develop during childhood.
What is the innermost layer component of a bone?
- Tissue that is compact. This is the tougher, outer layer of bone tissue.
- Cancellous tissue is a kind of tissue that has no cells. This is the sponge-like tissue that may be found inside bones.
- Subchondral tissue is a kind of connective tissue. Smooth tissue near the ends of bones, which is covered by another sort of tissue known as cartilage, is what we’re talking about. Cartilage is a type of connective tissue that is specialized and rubbery.
What is the outer layer of a bone called?
The periosteum is the term used to describe the outer surface of bone (say: pare-ee-OSS-tee-um). It’s a thin, thick membrane that includes nerves and blood arteries that supply nutrients to the bone and help it grow. A layer of compact bone is present in the next layer.
