Nerve system for sensing touch, temperature, body position, and pain
The somatosensory system, or somatic sensory system is a subset of the sensory nervous system. It has two subdivisions, one for the detection of mechanosensory information related to touch, and the other for the nociception detection of pain and temperature. The main functions of the somatosensory system are the perception of external stimuli, the perception of internal stimuli, and the regulation of body position and balance (proprioception). Mechanosensory information includes that of light touch, vibration, pressure and tension in the skin.
