Understanding Bone Marrow Types: Beyond Red and Yellow

In addition to yellow and red bones, there are three other types of bone marrow: white, brown, and black.

- Yellow bone marrow is composed primarily of fat cells, which store energy.

- Red bone marrow produces red blood cells, white blood cells, and platelets.

- White bone marrow is found in the long bones of the body and is composed of a mixture of fat cells, red blood cells, and white blood cells.

- Brown bone marrow is found in the sternum, vertebrae, and pelvic bones and is responsible for producing heat to help regulate body temperature.

- Black bone marrow is found in the bones of the skull and is composed of a mixture of red and brown bone marrow.
