Anterior Choroidal Artery Anatomy 6 Q&A

In this video, we will delve into the anatomy of the anterior choroidal artery, a crucial branch of the internal carotid artery that supplies several crucial structures of the brain important for vision and motor control. This video is part of a series of short questions and answers designed specifically for medical and anatomy students looking to enhance their knowledge of the human body. Overview of the Anterior Choroidal Artery The anterior choroidal artery originates from the posterior wall of the internal carotid artery between the origin of the posterior communicating artery and the internal carotid termination. It measures approximately 1 mm in diameter and has two segments: the cisternal segment, which extends from its origin until the choroidal fissure, and the intraventricular segment, which enters the choroidal fissure. Key Points to Remember Origin: The anterior choroidal artery originates from the internal carotid artery. Course: The artery curves medially to the inferomedial surface of the optic tract, then laterally to run along its lateral aspect and circumvents the cerebral peduncles to reach the lateral geniculate body. Vascular Territory: The cisternal segment supplies deep brain structures, including the posterior limb and retrolenticular part of the internal capsule, lateral thalamus, lateral cerebral peduncle, globus pallidus internus, and tail of the caudate nucleus. The intraventricular segment supplies the choroid plexus of the anterior part of the temporal horns of the lateral ventricles. Variants: The anterior choroidal artery may occasionally originate from the intracerebral carotid bifurcation, and duplication of the artery is reported in approximately 5% of cases. 0:00 Is the Anterior Choroidal Artery a branch of the Internal Carotid Artery? 0:24 Is the Anterior Choroidal Artery the first branch to originate from the Internal Carotid Artery? 0:46 Is the Anterior Choroidal Artery the last branch to originate from the Internal Carotid Artery? 1:09 What is the abbreviation of the Anterior Choroidal Artery? 1:27 The Anterior Choroidal Artery is a branch of the Internal Carotid Artery.
