Key Concepts

Long Bone Anatomy

Long bones are structured with distinct regions including the diaphysis (shaft), epiphyses (ends), and the medullary cavity. Understanding these divisions is crucial as each region has a unique composition and function, from providing structural support to hosting bone marrow.

Medullary Cavity

The medullary cavity is the central hollow area within the diaphysis of long bones. It is typically lined by a thin layer of cortical bone and contains bone marrow, which is vital for producing blood cells and storing fat.

Bone Marrow

Bone marrow is the soft, specialized tissue found within the medullary cavity of long bones. It plays a key role in hematopoiesis, the process of producing red blood cells, white blood cells, and platelets, and exists in both red and yellow forms depending on the physiological demands.
