Which type of bone consists of a central cylindrical shaft with an epiphysis at each end?

Long bones are characterized by their structure, which includes a central cylindrical shaft known as the diaphysis and an epiphysis at each end. This design is essential for the function of long bones, which include the limbs and play a critical role in movement and support. The shaft is primarily made of compact bone, which provides strength and rigidity, while the ends consist of spongy bone, which contains red marrow and is involved in the production of blood cells.

This unique structure allows long bones to endure the stress of physical activities while facilitating leverage and movement at joints. Additionally, long bones are essential for growth due to their epiphyseal plates, which are responsible for longitudinal growth during childhood and adolescence. Understanding the characteristics of long bones is fundamental in fields related to anatomy and exercise physiology, as they are pivotal in understanding biomechanics and functional movement.
