What is the posterior limb of the internal capsule?

What is the posterior limb of the internal capsule?

The posterior limb of internal capsule (or occipital part) is the portion of the internal capsule posterior to the genu. the fibers of optic radiation, from the lower visual centers to the cortex of the occipital lobe; acoustic fibers, from the lateral lemniscus to the temporal lobe.

What happens if the internal capsule is damaged?

Damage to this area can affect functions like speaking, chewing, and swallowing. As a result, individuals may struggle to swallow (dysphagia), have difficulty with eating, and/or struggle with speech (dysarthria and other motor speech disorders) after an internal capsule stroke.

What is the internal capsule responsible for?

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.

Where is the internal capsule located in the brain?

The internal capsule is a white matter structure situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the basal nuclei, separating the caudate nucleus and the thalamus from the putamen and the globus pallidus.

Is internal capsule white matter?

The internal capsule, a white matter structure, is a unique location where a large number of motor and sensory fibers travel to and from the cortex.

What arteries supply internal capsules?

The internal capsule and basal nuclei are supplied by perforating branches of the anterior cerebral artery (ACA), Heubner’s artery, middle cerebral artery (MCA), internal carotid artery (ICA) and anterior choroidal artery (AChA).

What supplies the posterior internal capsule?

What is blood supply of internal capsule?

The blood supply of the internal capsule is variable but is commonly from small perforating branches of the middle cerebral artery and anterior cerebral artery. In addition, the anterior choroidal artery from the internal carotid artery supplies the posterior limb and retrolentiform part of the internal capsule 3,4.
