The cutaneous senses are responsible for the perceptions of touch and pain, that are caused by stimulation of the

Cutaneous receptors in the skin are distributed all over the body, and each carry messages to locations in the brain
through pathways in the spinal cord
The Somatosensory system, includes: the cutaneous senses, which are responsible for perceptions such as touch and
pain
The somatosensory cortex (postcentral gyrus) receives tactile information from the body
