Anterior choroidal artery (Arteria choroidea anterior) The anterior choroidal artery is the preterminal branch of the communicating segment (C7) of the internal carotid artery. It supplies several subcortical structures (limbic system, basal ganglia, diencephalon), midbrain, temporal lobe and visual pathway.Anterior choroidal artery (Arteria choroidea anterior) The anterior choroidal artery is the preterminal branch of the communicating segment (C7) of the internal carotid artery.

What is anterior choroidal?
The anterior choroidal artery (AChA) is a branch of the intracranial internal carotid, arising distal to the ophthalmic artery but below the circle of Willis. Its size compares with that of cerebral surface artery branches, but its location makes it an uncommon site of occlusion that causes stroke.
What is the function of anterior choroidal artery?
The anterior choroidal artery (AChA) supplies several crucial anatomical structures of the brain important for vision and motor control. Identification of AChA is important because of its strategic and extensive area of supply as well as large variations in the territorial distribution.
What does the anterior cerebral artery supply?
The anterior cerebral artery (ACA) arises from the internal carotid at nearly a right angle. It sends deep penetrating branches to supply the most anterior portions of the basal ganglia. … To summarize, the ACA supplies the medial and superior parts of the frontal lobe, and the anterior parietal lobe.
What is in the circle of Willis?
The Circle of Willis is the joining area of several arteries at the bottom (inferior) side of the brain. At the Circle of Willis, the internal carotid arteries branch into smaller arteries that supply oxygenated blood to over 80% of the cerebrum.
What does the internal capsule do?
The internal capsule describes a region deep in the brain that functions as a communication pathway. The internal capsule allows communication between areas of the cerebral cortex and areas of the brainstem.
What is in the anterior limb of the internal capsule?
The anterior limb of internal capsule (or frontal part) contains: fibers running from the thalamus to the frontal lobe. … fibers connecting the cortex with the corpus striatum. fibers passing from the frontal lobe through the medial fifth of the base of the cerebral peduncle to the nuclei pontis.
What is the superior hypophyseal artery?
The superior hypophyseal arteries branch from the internal carotid arteries to supply the hypothalamus, where they form a capillary network in the median eminence, external to the blood-brain barrier.
