[[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]].
