Trancred 2005 The Paracentral Lobule includes the primary motor and somatosensory areas for the leg and foot and is important in the control of voluntary movements and the localisation and perception of somatosensory stimuli in the leg and foot. Structures: Anterior Cerebral a. Central Sulcus Cerebrum Middle Cerebral a. Postcentral Gyrus Precentral Gyrus Primary Motor Area Primary Somatosensory Area Information: The Paracentral Lobule is a region of cortex on the medial surface of the cerebrum which surrounds the medial end of the central sulcus. It is formed by the medial ends of the precentral and postcentral gyri and represents the primary motor and somatosensory areas for the leg and foot. The paracentral lobule is of some clinical importance because it is supplied by branches of the anterior cerebral artery whereas the remainder of the pre- and postcentral gyri are supplied by branches of the middle cerebral artery. Thus, lesions of the anterior cerebral artery result in loss of sensation and paralysis of muscles in the contralateral leg and foot, whereas lesions of the middle cerebral artery do not affect the leg and foot. |
