Final answer:
The chief sensory nucleus in the pons and the spinal trigeminal nucleus in the medulla receive tactile and pressure sensations from CN V distributions.
Step-by-step explanation:
The trigeminal system of the head and neck is divided into several nuclei that receive different types of sensory information.
The chief sensory nucleus, located in the pons, is responsible for receiving light touch and proprioceptive information about the mandible.
It relays this information to the thalamus and ultimately to the parietal lobe. The spinal trigeminal nucleus, located in the medulla, receives information about crude touch, pain, and temperature and relays it to the thalamus and cortex.
