Contains nerve fibers

Contains nerve fibers

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

Answer: (A)

Nerve supply to tissues is described by innervation; tissues that have nerve fibers are innervated. Nerve fibers provide sensory and signaling roles, which is why bone coverings and marrow can have nerves and are described in terms of innervation. Cartilage lacks blood vessels and nerves (it is aneural and avascular), so it does not contain nerve fibers. Vascular describes the presence of blood vessels, not nerves, so it doesn’t address nerve fiber content. While bone marrow can have nerves, the term that directly describes the presence of nerve fibers is innervated.
