Middle cerebral artery

The middle cerebral artery is the largest of the three major arteries that distributes blood to the cerebrum. It is found in the internal carotid. Blood is supplied to lateral areas of the frontal, temporal, and parietal lobes. The frontal, temporal, and parietal lobes control the sensory functions of the arms, throat, hands, and face. The parts of the middle cerebral artery are: Horizontal segment: Creates holes with lateral lenticulostriate arteries. These arteries are responsible for irrigating the basal ganglia Sylvian segment: Supplies blood to the temporal lobe and insular cortex. The branches may divide or bifurcate or trifurcate into trunks. This segment also contains the operculum, which extend from the insula in the direction of the cortex. Cortical Segments: provides irrigation for the cortex The middle cerebral artery is often obstructed during a stroke. Neuroimaging tools such as CT scans are commonly used diagnostic tests to determine strokes. Doctors search for acute middle cerebral thrombosis on a non-contrast CT scan because this is a very sound indicator of thromboembolic middle cerebral artery obstruction.
