The middle cerebral artery (a. cerebri media) , the largest branch of the internal carotid, runs at first lateralward in the lateral cerebral or Sylvian fissure and then backward and upward on the surface of the insula, where it divides into a number of branches which are distributed to the lateral surface of the cerebral hemisphere.
The middle cerebral artery is divided into 2 segments (M1 and M2) in the terminologia anatomica but surgical and radiological approaches use 4 segments (M1, M2, M3, M4) that are well described by Gibo et al (Microsurgical anatomy of the middle cerebral artery - GiboH et al. - J Neurosurg. 1981 Feb;54(2):151-69.) :
The branches (rami) of the MCA can be described by the areas that they irrigate.
