MCQ IN MEDICINE

Detailed explanation-1: -The supramarginal gyrus (plural: supramarginal gyri) is a portion of the parietal lobe of the brain. It is one of the two parts of the inferior parietal lobule, the other being the angular gyrus . It plays a role in phonological processing (i.e. of spoken and written language) and emotional responses.

Detailed explanation-2: -The supramarginal gyrus is part of the somatosensory association cortex, which interprets tactile sensory data and is involved in perception of space and limbs location. It is also involved in identifying postures and gestures of other people and is thus a part of the mirror neuron system.

Detailed explanation-3: -The angular gyrus is a horseshoe shaped region of the inferior parietal lobule. The region is located posterior to the supramarginal gyrus, the second region that forms the inferior parietal lobule. This region is known as the Brodmann area 39.

Detailed explanation-4: -The inferior parietal lobule (IPL), also known as Geschwind territory or area, is one of the three divisions of the parietal lobe. It is composed of a supramarginal gyrus rostrally and an angular gyrus caudally. It is involved with sensorimotor integration, spatial attention and visuomotor and auditory processing 1.
