Question

Erythropoiesis takes place in which section of long bones?

Tap to reveal answer

Answer

The ends of long bones, called epiphyses, contain spongy bone. Spongy bone contains red bone marrow, which is the site of erythropoiesis.

The shaft of the long bone is the diaphysis and houses yellow bone marrow, which mainly functions for fat storage. Articular cartilage is found on the exterior of the bone and helps to lubricate and provide cushioning for joints. Lacunae are small gaps in the hydroxyapatite matrix that house osteocytes. The Haversian canal runs through the center of an osteon and serves to house the blood vessels and nerves associated with bone.
