somatosensory association.

Detailed explanation-1: -The primary somatosensory cortex is called S1. This area of the cerebral cortex receives sensory information from the somatic senses, plus proprioceptive senses and some visceral senses. It is located on the postcentral gyrus of the parietal lobe, as shown in Figure 4.3. 6.
Detailed explanation-2: -The cranial nerves III, IV and VI carry many large proprioceptive fibres (12-16 micrometer) to the central nervous system. These nerves also contain many small fibres of the y-range (2-6 micrometer) which innervate the intrafusal muscle fibres in the spindles.
Detailed explanation-3: -Two areas near the base of the brain-the cerebellum and the brainstem-are heavily involved in coordinating proprioception inputs and outputs. Most of the time, we respond without having to think about it, and we are often unaware of these ongoing adjustments.
