What is the function of the middle cerebral artery?

The MCA (middle cerebral artery) is the largest of three major arteries that supplies fresh blood to the brain. It branches from the internal carotid arterial. It supplies blood to the lateral (side), areas of the frontal and temporal lobes.



What happens if the middle cerebral artery becomes blocked?

An MCA stroke refers to an interruption in blood flow to areas of the brain that receive blood from the middle cerebral artery. A small blockage of a branch of the middle cerebro artery can result in a small vessel stroke, which affects a small portion of the territory of the middle cerebral blood artery.

Also, where is the middle cerebral artery? The MCA (middle cerebral artery) is one of three major paired arterial that supply blood to cerebrum. The MCA originates in the internal carotid, and then continues into the lateral. It branches off and projects to many areas of the lateral cerebral cortex.

What are some signs of the middle cerebral blood vessels?

Signs & Symptoms

  • Hemiparesis, or hemiplegia in the lower half of contralateral face.
  • Hemiparesis (or hemiplegia) of the contralateral upper or lower extremities
  • Sensory loss of the contralateral arm, leg, and face
  • Ataxia of contralateral extremities*

Are there two middle cerebral veins?

Middle cerebral artery. The MCA is the smaller of the two main terminal branches, the other being the anterior cerebro artery. It runs laterally into the lateral.
