Mca

The middle cerebral artery ( MCA) is one of the three major paired arteries that supply blood to the brain. The MCA arises from the Gross anatomy Segments The MCA is divided into four segments: • M1: sphenoidal or horizontal segment • originates at the terminal bifurcation of the internal carotid artery • courses laterally parallel to the sphenoid ridge • terminates at one of two points (controversial; see below note*): • at the genu adjacent to the • at the main bifurcation • M2: insular segment • originates at the genu/limen insulae or the main bifurcation (see above) • courses posterosuperiorly in the • terminates at the • M3: opercular segment • originates at the circular sulcus of the insula • courses laterally along the frontoparietal • terminates at the external/superior surface of the • M4: cortical segment • originates at the external/top surface of the Sylvian fissure • courses superiorly on the lateral convexity • terminates at their final cortical territory *The point where the M1 (sphenoidal) segment becomes the M2 (insular) segment is not agreed upon. As originally described by Fischer in 1938, the M1 segment ends where the artery turns 5. Although the bifurcation coincides with the genu in the classically described anatomy, most patients have a nonclassical bifurcation that occurs proximal or distal to the genu 6.
