Right middle cerebral artery

Looks like

The largest branch of the internal carotid, running sideways in the deep groove between the frontal and temporal lobes and fanning over the brain's side.

What it does

Supplies most of the outer brain surface: movement and feeling of face and arm, speech (usually left side) and hearing areas.

Keeping it well

The most common site of stroke. Face and arm weakness, lost speech or neglect of one side: call an ambulance, clot treatment is time-critical.
