| somatic sensory cortex | Somatosensory cortex, the region of the cerebral cortex receiving the somatic sensory radiation from the ventrobasal nucleus of the thalamus; it represents the primary cortical processing mechanism for sensory information originating at the body surfaces (touch) and in deeper tissues such as muscle, tendons, and joint capsules (position sense); it corresponds approximately to Brodmann's areas 1, 2, 3 on the postcentral gyrus. Synonym: somesthetic area. (05 Mar 2000) |

| somatic swallow | A swallowing pattern with muscular contractions which appear to be under control of the person at a subconscious level; distinguished from visceral swallow. Visceral swallow, the immature swallowing pattern of an infant or a person with tongue thrust, resembling peristaltic wavelike muscular contractions observed in the gut; adult or mature swallowing is more volitional and therefore somatic.
