The brainstem and cerebellum get their blood from important arteries. Most of these arteries come from a system called the vertebrobasilar system. Let’s break down the major sources that supply blood to these parts of the brain:
Vertebral Arteries: These arteries run up your neck. They help supply blood to the back part of your brain. They send branches that reach the lower part of the brainstem, which includes the medulla.
Basilar Artery: This artery is made when the vertebral arteries join together. It supplies blood to the pons and the upper segments of the brainstem.
Posterior Cerebral Arteries (PCA): These arteries branch off from the basilar artery. They deliver blood to the midbrain and parts of the cerebellum.
Anterior Inferior Cerebellar Artery (AICA) and Superior Cerebellar Artery (SCA): These arteries are very important for the cerebellum. They ensure that it gets enough blood to help with coordination and balance.
Knowing about these blood vessels is important. It helps us understand health issues like strokes, which can affect how the brainstem or cerebellum works.
