The somatosensory system is a part of the nervous system that processes sensory information from the body. It allows us to perceive sensations such as touch, temperature, pain, and body position. This system includes various receptors in the skin, muscles, and joints that send signals to the brain for interpretation. Key components of the somatosensory system include the skin receptors, which detect external stimuli, and the proprioceptors, which provide information about body position and movement. The brain then integrates this information to help us respond appropriately to our environment and maintain balance and coordination.
