What term describes a network of intersecting spinal nerves?

• A. Peripheral nerves
• B. Cortex, Frontal lobe
• C. Brainstem
• D. Plexus

Answer: (D)

The term describes a network formed by the ventral rami of spinal nerves that come together and branch to supply different regions. Such interlacing nerve networks are called a plexus. Examples include the cervical, brachial, lumbar, and sacral plexuses, which organize fibers to the head, neck, upper limb, and lower limb, respectively. In contrast, peripheral nerves are individual bundles of fibers, and brain structures like the cortex or brainstem are parts of the central nervous system, not networks of intersecting spinal nerves. So the network term that fits is plexus.
