Occlusion of the aery supplying the marked area will lead to all EXCEPT:: (A) Urinary incontinence, (B) Rectal incontinence, (C) Apraxia, (D) Perianal anesthesia
Answer is B. Area marked: Medial aspect primary motor area & Somatosensory area Paracentral lobule Aery supplying: Anterior cerebral aery Medial aspects of the sensory motor homunculus: Contralateral lower limb & pa of pelvis & perineum Coical micturition center (CMC): - Located in the medial aspect of the frontoparietal coex. Apraxia: - Inability to perform motor tasks on command d/o a lesion in the cerebral hemisphere (Parietal lobe). However, rectal incontinence is not affected or controlled by the paracentral lobular. Rectal incontinence is affected by thoracolumbar region and somatic efferent damage.
