Question

the spinothalamic tract synapses in which spinal cord region?
dorsal horn
ventral horn
lateral horn
central canal

Explanation:

The spinothalamic tract is a sensory pathway. Sensory neurons enter the spinal cord and synapse in the dorsal horn. The dorsal horn is involved in processing sensory information like pain, temperature, and crude touch. The ventral horn is motor - related (contains motor neurons). The lateral horn is associated with the autonomic nervous system (sympathetic neurons in thoracic - lumbar regions). The central canal is a cerebrospinal fluid - filled structure and not a site of synapse for the spinothalamic tract.

Answer:

A. Dorsal horn
