Calcarine artery

Calcarine Artery

The calcarine artery is a branch of the posterior cerebral artery that supplies the visual cortex.

The calcarine artery is a branch of the posterior cerebral artery that supplies the visual cortex. It is named after the calcarine fissure, which it runs along in the occipital lobe of the brain.

Anatomy

The calcarine artery arises from the posterior cerebral artery, which is a branch of the basilar artery. It travels along the calcarine fissure, a deep groove in the occipital lobe, and supplies blood to the visual cortex, the part of the brain responsible for processing visual information.

Clinical significance

Damage to the calcarine artery can lead to visual field defects, such as homonymous hemianopsia, a condition in which vision is lost in the same side of both eyes.
