Question

which best describes the function of the corticospinal tract? carries efferent motor signals transmits pain and temperature sensations carries afferent sensory signals for vibration relays proprioceptive information

Explanation:

The corticospinal tract is a major motor pathway in the central nervous system. Efferent signals are motor signals sent from the brain to muscles. The other options describe functions of sensory tracts: pain/temperature is carried by spinothalamic tracts, vibration sensory signals and proprioceptive information are handled by dorsal column-medial lemniscus pathways.

Answer:

Carries efferent motor signals
