Each part of the body is represented on the somatosensory cortex in proportion to its sensitivity to physical sensations. This is known as a sensory homunculus, where body parts with more sensory receptors have larger representations on the somatosensory cortex. For example, the hands, lips, and tongue have a larger representation compared to other body parts because they have a high density of sensory receptors.
