ANATOMY

Detailed explanation-1: -All but one of your senses travel through your somatic nervous system to reach your brain (sight is the exception because your retina and optic nerve connect directly to your brain). The other senses on your head-sound, smell, taste and touch-all use your somatic nervous system to reach your brain.

Detailed explanation-2: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.

Detailed explanation-3: -Nerves relay the signals to the brain, which interprets them as sight (vision), sound (hearing), smell (olfaction), taste (gustation), and touch (tactile perception).

Detailed explanation-4: -The sensation of touch is mediated by mechanosensory neurons that are embedded in skin and relay signals from the periphery to the central nervous system. During embryogenesis, axons elongate from these neurons to make contact with the developing skin.

Detailed explanation-5: -In physiology, the somatosensory system is the network of neural structures in the brain and body that produce the perception of touch (haptic perception), as well as temperature (thermoception), body position (proprioception), and pain.
