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. The somatosensory system is spread through all major parts of the vertebrate body. It consists both of sensory receptors and sensory neurons in the periphery (skin, muscle and organs for example), to deeper neurons within the central nervous system. 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. The somatosensory system is a model sensory system for understanding how external stimuli are represented in the brain. It demonstrates both the precision of neural coding in primary sensory areas and the adaptability of the brain in response to changes in input or experience. The somatosensory cortex is the part of your brain that processes information from your body’s senses – like touch, pressure, temperature, and pain. It also helps with proprioception, which is your awareness of body position and movement. The somatosensory system is also known as the somatic senses, touch or tactile perception. Anatomically speaking, the somatosensory system is a network of neurons that help humans recognize objects, discriminate textures, generate sensory-motor feedback and exchange social cues. Somatosensation is a mixed sensory category, and is mediated, in part, by the somatosensory and posterior parietal cortices. They underlie the ability to identify tactile characteristics of our surroundings, create meaning about sensations, and formulate body actions related to the sensations [1]. 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. 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 is regulated by receptors that are spread throughout the body and measure a number of different sensory modalities in the body. These sensations can be divided into three main divisions: external stimuli, internal stimuli, and the sense of where the body is in space.
