Paracentral lobule

Neurons in paracentral lobule are concerned with: • Motor and sensory innervations of the contralateral lower extremity • Regulation of physiological function such as blushing, defecation and micturition ==Blood supply==

It is supplied by branches of the anterior cerebral artery. ==Applied anatomy==

Damage of paracentral lobule occurs from occlusion of anterior cerebral artery. Characteristic manifestations include: • Contralateral lower limb muscle weakness • Urinary incontinence ==Gallery==
