Identify the anatomical region

The question asks for the term that describes the expanded end of a long bone.

Analyze the given options

We evaluate each anatomical term provided in the choices:

• endosteum: The thin vascular membrane lining the inner medullary cavity of a bone.
• medullary cavity: The central cavity of bone shafts where red bone marrow and/or yellow bone marrow is stored.
• diaphysis: The shaft or central part of a long bone.
• periosteum: A dense layer of vascular connective tissue enveloping the bones except at the surfaces of the joints.
• epiphysis: The expanded end portion of a long bone, which articulates with another bone.

Match definition with correct term

The expanded end of a long bone is anatomically defined as the epiphysis.
