Question

question 33
this spinal cord structure pertains to swelling where youd transmit sensory or afferent input:
○ ventral horn
○ ventral root
○ dorsal root ganglion
○ central canal

Explanation:

To solve this, we analyze each option:

• Ventral horn: Involved in motor (efferent) output, not sensory input.
• Ventral root: Carries motor (efferent) fibers from the spinal cord.
• Dorsal root ganglion: Is a swelling (ganglion) of the dorsal root that contains cell bodies of sensory (afferent) neurons, responsible for transmitting sensory input.
• Central canal: Filled with cerebrospinal fluid, not related to sensory input transmission.

So the correct option is the one related to sensory/afferent input transmission via a swelling.

Answer:

C. dorsal root ganglion
