What does the anterior cerebellar artery supply?
The anterior inferior cerebellar artery supplies the middle cerebellar peduncle, lower lateral pons, anteroinferior surface of the cerebellum, flocculus and the choroid plexus of the lateral ventricle.
Does anterior cerebral artery supply lower limb?
Note that several small frontal and parietal branches also cross onto the superolateral cerebral surface to supply the superior parts of the precentral and postcentral gyri. These areas are responsible for motor and sensory functions in the lower limb.
What does the anterior communicating artery supply?
Branches and supply These arteries penetrate the medial part of the anterior perforated substance and supply the optic chiasma, lamina terminalis, preoptic and supraoptic areas of the hypothalamus, parolfactory areas of the frontal cortex, anterior columns of the fornix and cingulate gyrus.
What does posterior cerebral artery supply?
The Posterior Cerebral Artery (PCA) supplies the occipital lobe, the inferior part of the temporal lobe, and various deep structures including the thalamus and the posterior limb of the internal capsule.
Which cerebral artery supplies blood to Broca’s area?
Superior branches of MCA supply these key functional areas: Broca’s area and other related gray and white matter important for language expression–in the language-dominant (usually left) hemisphere.
What artery supplies the hand area of the cerebral hemisphere?

What are the segments of the ICA?
The authors’ classification has the following seven segments: C1, cervical; C2, petrous; C3, lacerum; C4 cavernous; C5, clinoid; C6, ophthalmic; and C7, communicating. This classification is practical, accounts for new anatomic information and clinical interests, and clarifies all segments of the ICA.
What is anterior cerebral artery aneurysm?
Anterior Communicating Artery Aneurysms. ACoA aneurysms arise within the complex of the two anterior cerebral arteries at their anastomosis via the ACoA. They are ensconced by the anterior cerebral arteries and branches leading to a complex and highly variable dissection (Fig. 67-19).
Which of the following Gyral structures is supplied by the posterior cerebral artery?
The posterior cerebral artery supplies regions in the posterior parietal lobe, inferior temporal lobe and occipital lobe (blue shade in Figure A18). Included in this region are primary and associational (higher-order) visual areas in each lobe and ‘limbic’ regions in the posterior cingulate and parahippocampal gyri.
Is the anterior cerebral artery the same as the anterior communicating artery?
Anterior Cerebral and Anterior Communicating Artery The anterior cerebral artery (ACA) arises below the anterior perforated substance and runs anteromedially to the interhemispheric fissure, where it joins the opposite ACA by way of the anterior communicating artery (ACoA).
What portion of the brain is served by the anterior and middle cerebral arteries?
The major branches that arise from the internal carotid artery—the anterior and middle cerebral arteries—form the anterior circulation that supplies the forebrain (Figure 1.20B).
What does the pontine artery supply?
The pontine arteries are comprised of tiny blood vessels that are part of the posterior cerebral circulation system. The pontine arteries are responsible for helping the body deliver oxygen-rich blood from the heart to the brain.
How many anterior cerebral arteries are there in the brain?
It’s really quite simple: there are usually two anterior cerebral arteries, with right and left A1 and A2 segments. Sometimes, however, there is only one A2 segment, with no ACOM.
What is a cerebral aneurysm?
Your browser does not support the audio element. A cerebral or intracranial aneurysm is an abnormal focal dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall. The vessel develops a “blister-like” dilation that can become thin and rupture without warning.
What are the treatment options for cerebral aneurysm?
Broadly, three treatment options for people with the diagnosis of cerebral aneurysm include: 1 medical (non-surgical) therapy 2 surgical therapy or clipping and 3 endovascular therapy or coiling with or without adjunctive devices More
Is the anterior cerebral artery a telencephalic vessel?
Overview: The anterior cerebral artery is a unique vessel, in many respects. Phylogenetically, it is among the oldest vessels in the telencephalic species.
