Multiple Choice

Which statement correctly describes an osteon in the microscopic anatomy of bones?

An osteon is a type of bone cell responsible for bone resorption.

An osteon is a network of trabeculae found in spongy bone.

An osteon is a flat, sheet-like structure found in the outer layer of bones.

An osteon is a cylindrical structure that contains a central canal surrounded by concentric lamellae.

Verified step by step guidance

Begin by understanding the basic structure of an osteon, which is the fundamental unit of compact bone.

Recognize that an osteon is cylindrical in shape and is oriented parallel to the long axis of the bone.

Identify the central canal, also known as the Haversian canal, which runs through the center of the osteon and contains blood vessels and nerves.

Note the concentric lamellae, which are layers of calcified matrix surrounding the central canal, providing strength and support to the bone.

Understand that osteons are tightly packed together in compact bone, contributing to its dense and strong nature, unlike the trabeculae found in spongy bone.
