Posterior cerebral artery
Posterior Cerebral Artery
The Posterior Cerebral Artery (pronunciation: poh-STEER-ee-or sə-REE-brəl AHR-tə-ree) is one of the main arteries supplying blood to the brain. It is a major part of the Circle of Willis, a circular network of arteries that provides blood to the brain and surrounding structures.
Etymology
The term "Posterior Cerebral Artery" is derived from the Latin words 'posterior' meaning 'behind', 'cerebrum' meaning 'brain', and 'arteria' meaning 'windpipe, artery'. Thus, it refers to the artery located behind the brain.
Anatomy
The Posterior Cerebral Artery originates from the Basilar Artery, which is formed by the union of the two Vertebral Arteries. It travels towards the back of the brain, supplying blood to the Occipital Lobe, the Temporal Lobe, and parts of the Thalamus and Midbrain.
Clinical Significance
Blockage or damage to the Posterior Cerebral Artery can lead to Posterior Cerebral Artery Syndrome, a condition characterized by a variety of neurological symptoms including visual disturbances, memory loss, and difficulty with spatial awareness. Treatment typically involves addressing the underlying cause of the blockage or damage, such as Atherosclerosis or Stroke.
