Bundles of neuronal dendrites or axons enclosed within connective tissue are designated as:
Show answer Hide answer
Answer: B. Nerves
Explanation
Nerves consist of bundles of neuronal axons or dendrites wrapped in connective tissue outside the central nervous system. Connective tissue sheaths protect these delicate neural fibers as they transmit signals throughout the body. Peripheral nerves act as high-speed cables connecting central brain and spinal structures to bodily organs. Neurons feature long cellular extensions called axons and dendrites capable of propagating electrical impulses. Endineurium, perineurium, and epineurium are the protective connective tissue layers surrounding peripheral nerve bundles. The peripheral nervous system relies on these structured nerve bundles to relay motor and sensory data.
Option A refers to the brain which is the central command organ rather than a bundle of neuronal fibers. Option C names ganglia which are clusters of neuronal cell bodies rather than axonal fiber bundles. Option D describes the spinal cord which is a massive central nervous system tract rather than a peripheral nerve.
