Anterior paracentral gyrus
Gyrus paracentralis anterior
Definition
The front part of the paracentral lobule is known as the anterior paracentral gyrus. This gyrus is formed by the inner part of the precentral gyrus which extends to the medial surface of cerebral hemisphere. It belongs to the frontal lobe and is responsible for controlling the leg region as the primary motor area. Additionally, it may also include the supplementary motor regions and the cortical control center for defecation and micturition.
The anterior paracentral gyrus is bounded at the front by the precentral sulcus, which extends towards the inner part of the cerebral hemisphere. At this point, it is referred to as the paracentral sulcus, which separates the anterior paracentral gyrus from the medial frontal gyrus.
