Detailed explanation-1: -Long bones contain a diaphysis which makes up the shaft of the bone and an epiphysis which make up the two ends of the bone.

Detailed explanation-2: -Long bones of the leg include the femur, tibia, fibula, metatarsals, and phalanges. The clavicles (collar bones) are also long bones. Long bones provide the leverage we need for moving our bodies and for manipulating our environment. All long bones have two main parts: diaphysis and epiphysis.

Detailed explanation-3: -The epiphysis is the enlarged wide end of a long bone that articulates with other bones at joints; this portion of bone is only found on the ends of long bones. It is widened to strengthen joints and allow for ligaments and tendons to attach. It is separated from the rest of the bone by a growth plate.

Detailed explanation-4: -A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3. 1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone.

Detailed explanation-5: -The epiphysis is the expanded or rounded end portion of a long bone. It has red bone marrow-producing erythrocytes. The diaphysis is the shaft portion of a long bone with cortical tissue. It has bone marrow and adipose tissue.
