Middle Cerebral Artery Anatomy Branches Supply Kenhub Supplies most of the temporal lobe anterolateral frontal lobe and parietal lobe. The MCA arises from the internal carotid and continues into the lateral sulcus where it then branches and projects to many parts of the lateral cerebral cortex.

It also supplies blood to the anterior temporal lobes and the insular cortices. This artery also supplies blood to the primary sensory and motor areas of the face hand throat and arm 2. The anterior cerebral arteries supply the anteromedial portion of the cerebrum.

The middle cerebral arteries supply the majority of the lateral surface of the hemisphere except the superior portion of the parietal lobe via the ACA and the inferior portion of the temporal lobe and occipital lobe via the PCA.

It branches off the internal carotid artery. Course From its origin the middle cerebral artery continues into the lateral sulcus of the cerebrum. 3 rows The middle cerebral artery MCA is a terminal branch of the internal carotid.

Cortical The superior upper or suprasylvian MCA branch gives rise to several arteries that supply much of the lateral and inferior frontal lobe and the anterior lateral parts of the parietal lobe. The middle cerebral artery MCA is the phylo-genetically youngest cerebral vessel. Arteria cerebri media is one of the terminal branches of the internal carotid artery.

Function It supplies the greater part of the lateral cerebral surface including the main motor and sensory areas as well as giving the striate arteries which supply deep structures including the internal capsule Clinical Significance The middle cerebral artery is the most common pathologically affected blood vessel overall Embolism of the MCA.
