Which location on the body has the largest region of somatosensory cortex representing it, according to the sensory homunculus? A. Elbow B. Lips C. Neck D. Thigh

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

to process these sensations to the part of the brain which is known as the

parietal lobe

lips

Explanation: The sensory homunculus is a mapping that is done and it allows the location of various somatosensory receptors in the body mapped onto a somatosensory cortex.

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
