What is pica arteries?

The term "pica arteries" is used to refer to the arteries that supply the brainstem. The brainstem is a crucial part of the brain that controls many important functions such as breathing, heart rate, and blood pressure. The pica arteries are found at the back of the brainstem and are responsible for carrying blood to this area. There are two pica arteries, one on each side of the brainstem, and they are a branch of the vertebral artery. If there is a blockage in one or both of these arteries, it can cause a stroke in the brainstem, which can result in severe and often permanent neurological symptoms such as paralysis, loss of sensation, difficulties with speech, and vision problems. Therefore, it is very important to seek medical attention quickly if you experience symptoms of a stroke, such as sudden weakness or numbness on one side of the body, difficulty speaking or understanding speech, sudden vision loss, or a severe headache.
