Somatosensory system

Touch is a crucial means of receiving information. This photo shows tactile markings identifying stairs for visually impaired people.

Touch can result in many different physiological reactions. Here, a baby laughs at being tickled by an older sister.

The cortical homunculus, a map of somatosensory areas of the brain, was devised by Wilder Penfield.

The somatosensory system (also somatosensory nervous system or SNS) is a complex system of nerve cells that responds to changes to the surface or internal state of the body. Nerve cells called "sensory receptors" (including thermoreceptors, mechanoreceptors, chemoreceptors and nociceptors) send signals along a chain of nerve cells to the spinal cord where they may be processed by other nerve cells and then relayed to the brain for further processing. Sensory receptors are found in many parts of the body including the skin, epithelial tissues, skeletal muscles, bones and joints, internal organs, and the cardiovascular system.
