Middle cerebral artery trunks from bifurcation to emergence from Sylvian fissure.

the superior M2 trunk does not give any branches to the temporal lobe

M2: from bi (tri) furcation to origin of cortical branches (circular sulcus of insula); also known as insular segment.

The vascular supply of the insula is mainly provided by the M2 segment of the middle cerebral artery, which constitutes a substantial obstacle to any open or stereotactic procedure aiming at the insular region.

The long insular arteries originate from the insular portion of the middle cerebral artery and supply the corona radiata and the descending motor tract.
