Which term describes bone that contains nerve fibers?

• A. Innervated
• B. Vascular
• C. Cartilage
• D. Bone Marrow

Answer: (A)

Nerve supply to a tissue is called innervation. In bones, nerves are mainly in the periosteum, the outer layer that covers the bone, and these nerves carry sensory information, including pain, and help regulate bone remodeling. So describing bone as innervated captures the idea that it contains nerve fibers. Vascular would refer to blood vessels, which bones do have but that describes blood supply rather than nerve presence. Cartilage is avascular and lacks nerves, so it wouldn’t be described as having nerve fibers. Bone marrow is a distinct internal tissue within bone that has its own nerves, but the term describing the bone’s nerve supply is innervation.
