What arteries supply the thalamus?

What arteries supply the thalamus?

The thalamus derives its blood supply from a number of arteries: the polar artery (posterior communicating artery), paramedian thalamic-subthalamic arteries, inferolateral (thalamogeniculate) arteries, and posterior (medial and lateral) choroidal arteries. These are all branches of the posterior cerebral artery.

What does posterior cerebral artery supply?

The cortical branches of PCA supply the posterior medial parietal lobe and the splenium of the corpus callosum, inferior and medial part of the temporal lobe including the hippocampal formation, and the medial and inferior surfaces of the occipital lobe. …

What artery supplies the cerebral peduncle?

The anteroinferior cerebellar artery (AICA) supplies the pons, the facial and spinal trigeminal nucleus and tract, as well as the inferior and middle cerebellar peduncles and spinothalamic tract.

Where is posterior cerebral artery located?

occipital lobe
The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral arteries.

What are the major symptoms a person will display who has had a PCA stroke?

Patients with posterior cerebral artery (PCA) infarcts present for neurologic evaluation with symptoms including the following:

• Acute vision loss.
• Confusion.
• New onset posterior cranium headache.
• Paresthesias.
• Limb weakness.
• Dizziness.
• Nausea.
• Memory loss.

Which lobe is the thalamus in?

The involvement of thalamic nuclei in sensory systems Signals are sent to the lateral geniculate nucleus of the thalamus which then forwards them onto the primary visual cortex (area V1) in the occipital lobe.

What causes posterior circulation stroke?

The most common causes of posterior circulation large artery ischemia are atherosclerosis, embolism, and dissection. Dolichoectasia (elongation and tortuosity) of the vertebral and basilar arteries is another occasional cause.

What is the cerebellar artery?

A cerebellar artery is an artery that provides blood to the cerebellum. Types include: Superior cerebellar artery. Anterior inferior cerebellar artery. Posterior inferior cerebellar artery.

Where does posterior cerebral artery come from?

The left and right posterior cerebral artery arises from the bifurcation of the basilar artery, which occurs at the superior border of the pons, posterior to the dorsum sellae. From there, the posterior cerebral artery continues laterally along the superior border of the pons.

What is the blood supply of the thalamus?

Blood supply. The thalamus is chiefly supplied by small perforating end-arteries arising from the posterior cerebral artery. The thalamus has four vascular territories 1-3: anterior (or tuberothalamic): supplied by thalamotuberal (or polar) arteries which are branches of the posterior communicating artery.

What does the posterior cerebral artery supply?

The posterior cerebral artery (PCA) is one of a pair of arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain.

What is posterior cerebral artery?

Posterior Cerebral Artery (PCA) is a branch of basilar artery, which are formed by the union of two vertebral arteries. The nidus measured 7.5 X 4 X 3.5 cm with supply predominantly from multiple feeders from hypertrophied left posterior cerebral artery and left middle cerebral artery.
