This maps helps to view the sensitive part of the body such as the lower face, lips. The projection of this sensitive body part is based on the number of corticles it has. more receptors are linked to cortex with large mapping area.
The lips response to stimulus due the large number of receptor it has and it has the largest region of somatosensory cortex
The location on the body has the largest region of somatosensory cortex
representing it is the lips.
Somatosensory cortex helps to process somatic sensations such as touch,
pressure, temperature, and pain through specialized receptors.
The lips is found in the mouth region and in close proximity with the tongue
which is the organ for taste. It is rich in somatosensory receptors which help
