Artery of precentral sulcus

Looks like

A middle cerebral branch running up in the groove in front of the motor strip (prerolandic artery).

What it does

Supplies the back of the frontal lobe, including movement planning areas and, on the dominant side, speech production (Broca's area).

Keeping it well

Its blockage can cause halting, effortful speech and weakness of the opposite face and arm.
