What does the somatosensory system include?

The somatosensory system encompasses the network of nerves responsible for processing sensory information from throughout the body, particularly related to touch, proprioception (the sense of body position), temperature, and pain. Nerves located in the skin, muscles, and joints are integral to this system as they relay critical sensory data to the brain, allowing for the perception of various physical sensations. This system plays a crucial role in helping individuals navigate their environment and respond to physical stimuli effectively.

While the inner ear is involved in balance, it is not part of the somatosensory system, which focuses more broadly on tactile and proprioceptive sensations. The ears are indeed associated with the vestibular system, which contributes to the sense of balance, but they do not comprise the somatosensory system itself. The heart and lungs are vital organs related to the circulatory and respiratory systems, respectively, and do not have a role in the somatosensory system's function.
