Figure 6.2: Somatosensory and Motor Homunculi

An illustration depicts the cortical maps, which show the somatosensory homunculus on the left and motor homunculus on the right. The somatosensory homunculus represents a map of brain areas dedicated to sensory processing for different body parts. The regions specializing in different parts of the body arranged from top to bottom are as follows: Genitals, leg, hip, trunk, neck, head, arm, elbow, forearm, hand, fingers, thumb, eye, nose, face, lips, teeth, gums, jaw, tongue, pharynx, and abdomen. The motor homunculus represents a map of brain areas dedicated to motor processing for different parts of the body. The regions specializing in different parts of the body arranged from top to bottom are as follows: Toes, knee, hip, trunk, shoulder, arm, elbow, wrist, hand, fingers, thumb, neck, brow, eye, face, lips, jaw, tongue, pharynx, and larynx.
