in the somatosensory homunculus, what body parts flank the hand area? what can happen if these parts are touched in an individual whose hand has been amputated (on the same side)?

The sensory homunculus represents a map of brain areas dedicated to sensory processing for the various anatomical divisions of the body. If a part of the body that is included in the sensory humunculus is amputated, then a person cannot feel something when that part of the body is touched.

Sensory homunculus

The sensory homunculus is a topographical representation of the sensory distribution of the body found in the cerebral cortex. This topography usually has body parts illustrated along the surface of the postcentral gyrus of the parietal lobe. The topography of the sensory homunculus corresponds to that of the contralateral side of the body.

Starting from the medial aspect of the postcentral gyrus, this area corresponds to the sensory areas of the genitals and lower extremities. Moves more laterally along the postcentral gyrus, an area superior to the superolateral gyrus corresponding to the neck, shoulders, and trunk. Along the lateral side of the postcentral gyrus, this region corresponds to the upper limb and hand. The inferolateral area of the postcentral gyrus corresponds to the facial and bulbar structures. Interestingly, the face is the structure that occupies most of the sensory area of the homunculus.
