Choroidal artery

Choroidal artery

The choroidal artery, as seen in Gray's Anatomy.

The choroidal artery is a branch of the posterior cerebral artery that supplies blood to the choroid plexus and the hippocampus in the brain. It is a vital component of the circulatory system in the brain, playing a crucial role in maintaining the health and function of these structures.

Structure

The choroidal artery originates from the posterior cerebral artery, one of the main arteries supplying the brain. It then travels through the choroidal fissure, a gap between the thalamus and the fornix, to reach the choroid plexus and the hippocampus.

Function

The primary function of the choroidal artery is to supply blood to the choroid plexus and the hippocampus. The choroid plexus is responsible for producing cerebrospinal fluid, which cushions the brain and spinal cord and helps to regulate the brain's environment. The hippocampus is involved in memory formation and spatial navigation.

Clinical significance

Damage to the choroidal artery can lead to a variety of neurological conditions, including stroke, memory loss, and hydrocephalus. It can also cause choroid plexus tumors, which are rare but can be serious.
