Where Is Choroidal Artery?

The artery is located within the parahippocampal gyrus, deep within the brain. It gives off approximately eight minor, perforating branches. This article will discuss the anatomy and function of the anterior choroidal artery.

What gives off the posterior choroidal artery?

A, Inferior view of the posterior cerebral artery. The medial posterior choroidal artery arises from the P1 and encircles the brainstem on the medial side of the P2 and P3, giving off small branches to the brainstem along its course. The P3 is formed by the branches in the quadrigeminal cistern. B, Enlarged view.

Which branch gives off the posterior choroidal artery?

The posterior choroidal arteries are usually given off as two branches from the P2 segment, a medial and lateral one. These branches supply the posterior portion of the thalamus and the choroid plexus.
