What part of the brain does the posterior inferior cerebellar artery supply?
What part of the brain does the posterior inferior cerebellar artery supply?
cerebellum
The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain.
Is a cerebellar infarction a stroke?
A cerebellar infarct (or cerebellar stroke) is a type of cerebrovascular event involving the posterior cranial fossa, specifically the cerebellum. Impaired perfusion reduces oxygen delivery and causes deficits in motor and balance control.
What does the inferior 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.
Is cerebral infarction curable?
Can stroke be cured? The short answer is yes, stroke can be cured — but it occurs in two stages. First, doctors administer specific treatment to restore normal blood flow in the brain. Then, the patient participates in rehabilitation to cure the secondary effects.
Where does the posterior cerebral artery come from?
The posterior cerebral arteries (bottom forks) arise from the basilar artery (center). 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.
Is dysmetria a form of ataxia?
More specifically, dysmetria is a type of cerebellar ataxia, which is the general term used to describe an abnormal coordination of movements.
What does dysmetria look like?
Dysmetria (English: wrong length) is a lack of coordination of movement typified by the undershoot or overshoot of intended position with the hand, arm, leg, or eye. It is a type of ataxia. It can also include an inability to judge distance or scale.
What is a P1 segment?
The P1 segment extends from the tip of the basilar artery to the origin of the posterior communicating artery. The P2 segment extends from the posterior communicating artery to the dorsal aspect of the midbrain ; this P2 segment can be further subdivided into anterior (P2A) and posterior (P2P) segments.
What does cerebellar artery mean?

What is pica artery?
The posterior inferior cerebellar artery (or PICA) is an artery that provides blood flow to the cerebellum, a part of the brain located behind the top of the brain stem, which helps with functions related to movement and coordination.
What is the posterior cerebellum?
The posterior lobe of cerebellum or neocerebellum, is the portion of the cerebellum below the primary fissure. It is sometimes called the neocerebellum since phylogenetically it is the newest part of the cerebellum.
