The _____ Nerve (Tract)carries Sensory Information Toward the Brain

Question

The _____ nerve (tract)carries sensory information toward the brain.
A) phrenic
B) pyramidal
C) corticospinal
D) spinothalamic

Accepted Answer

The spinothalamic nerve (tract) carries sensory information, such as temperature, pain, and pressure, from the spinal cord to the thalamus and then onto the cerebral cortex for processing. The phrenic nerve controls the diaphragm muscle for breathing, the pyramidal tract is responsible for controlling voluntary movements, and the corticospinal tract is also involved in voluntary movements, but specifically those of the limbs and trunk.
