The somatosensory system is the part of the sensory system concerned with the conscious perception of touch, pressure, pain, temperature, position, movement, and vibration, which arise from the muscles, joints, skin, and fascia. The system is integral to maintaining spatial awareness and motor coordination by providing continuous feedback about the body's internal and external environments. [1. The meaning of SOMATOSENSORY is of, relating to, or being the largely subconscious perception of stimuli associated with temperature, light touch, pain, body position, and movement through specialized receptors chiefly in the skin, joints, and muscles : relating to or involving somatosensation; also : relating to or being either of two regions in the parietal lobe that receive and process. Primary somatosensory cortex. In neuroanatomy, the primary somatosensory cortex is located in the postcentral gyrus of the brain 's parietal lobe, and is part of the somatosensory system. It was initially defined from surface stimulation studies of Wilder Penfield, and parallel surface potential studies of Bard, Woolsey, and Marshall. 23 Somatosensory Systems Casey Henley The somatosensory system relies on specialized receptors spread throughout the body to detect several distinct sensory modalities. Mechanoreceptors detect touch, nociceptors detect pain, thermal receptors detect temperature, and proprioceptors detect the position of the body in space. The somatosensory system is a complex network that functions as the body’s primary mechanism for perceiving physical sensation, providing awareness of both the external world and internal state. Unlike the five traditional senses, which rely on specialized, localized organs like the eyes or ears, the somatosensory network is distributed across the entire body. Sensory receptors are embedded. The somatosensory cortex is a brain region associated with processing sensory information from the body such as touch, pressure, temperature, and pain. The somatosensory system is the body’s network of nerve-based processes responsible for sensations such as touch, temperature, and body position. As a component of the sensory nervous system, it allows for the perception of both the external environment and the internal state of the body. Somatosensory system The somatosensory system includes the following cutaneous or skin senses: pressure (touch), pain (nociception), vibration and temperature, position sense (proprioception), and body movement (kinesthesis). The somatosensory system reacts to diverse stimuli and skin sensations through the mechanical, chemical, and thermal properties of the tissue in which the sensory nerves. The somatosensory system includes peripheral receptors and dedicated neural pathways that transduce environmental and internal stimuli to produce sensations of touch (mechanotransduction), temperature (thermoreception), pain (nociception), and body position (proprioception). The somatosensory system, or somatic sensory system, is a subset of the sensory nervous system. 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). [1].
