and fibrous covering of a long bone.

Expert Solution

Step 1

Long bones are strong, thick bones that offer structure, mobility, and strength. The femur (thigh bone) is a long bone. A long bone comprises two ends and a shaft. Even though they are modest in length, several bones in the fingers are classed as long bones.

Step 2

The diaphysis is a long bone's primary or midsection (shaft). It is made primarily of cortical bone and comprises fat cells and bone marrow.
In mammals, the epiphysis is the enlarged end of the long bones that ossifies separately from the bone shaft but gets fixed to the shaft once full growth is achieved.
The epiphyseal growth plate is the primary site of long-bone longitudinal growth. The proliferation and hypertrophy of cells, as well as the formation of the usual extracellular matrix, produce cartilage at this location.
The periosteum's outer layer is largely formed of elastic fibrous material like collagen. Blood vessels and nerves are also present. The periosteum's blood arteries assist the blood supply to the bones in the body.
