Webother stimulus types, such pressure, heat, or cold, etc. (Figure 1) Once a touch stimulus is detected by receptor endings in the skin, the neuron responds by initiating electrical impulses (action potentials) that are carried into the spinal cord. Impulses are then relayed to other neurons in the spinal cord and to the thalamus of the brain. WebSomatosensation is a mixed sensory category and includes all sensation received from the skin and mucous membranes, as well from as the limbs and joints. Somatosensation is also known as tactile sense, or more familiarly, as the sense of touch.
