Insula Anatomy

Anatomy of the insular region enables correct intraoperative identification of the number of major anatomical landmarks limen insulae peri insular sulci and the most distal lenticulostriate artery and facilitates the choice of the proper surgical approach. The insular cortex lies deep to the lateral sulcus sylvian fissure.

The insula is the fifth lobe of the brain and it is the least known.

From an embryological perspective the insular lobe is the structure between. Hidden under the temporal frontal and parietal opercula as well as under dense arterial and venous vessels its accessibility is particularly restricted. Insular lobe insula the insular lobe nsula is located in depth of sylvian fissure.

The insular cortex has been described in the medical literature as a separate lobe. The insular lobe is a part of the cerebral cortex located in both hemispheres. These findings disprove the theory that the insular lobe is an isolated island.

The cortex of the insula is covered by frontal operculum parietal operculum and temporal operculum. The pole po of the insula lies at the most anteroinferior point on the insula near to but separate from the apex. The accessory gyrus ac forms a variable portion of the upper anterior face of the anterior lobule and when large may contribute to the convexity surface as well.

The insula is a small region of the cerebral cortex located deep within the lateral sulcus which is a large fissure that separates the frontal and parietal lobes from the temporal lobe. In other words it gives meaning to bodily states by for example helping you experience pain as unpleasant. Like most brain regions though the insular cortex is not limited to a single function.

The insula is supplied by perforating branches from the middle cerebral artery. In each hemisphere of the mammalian brain the insular cortex also insula and insular lobe is a portion of the cerebral cortex folded deep within the lateral sulcus the fissure separating the temporal lobe from the parietal and frontal lobes.
