The anatomy of the brain is complex due its intricate structure and function. Thisamazing organ acts as a control center by receiving, interpreting, and directing sensoryinformation throughout the body. There are three major divisions of the brain. They arethe forebrain, the midbrain, and the hindbrain.
Anatomy of the Brain: Brain Divisions
The forebrain is responsible for a variety of functions including receiving andprocessing sensory information, thinking, perceiving, producing and understandinglanguage, and controlling motor function. There are two major divisions of forebrain: thediencephalon and the telencephalon. The diencephalon contains structures such as thethalamus and …show more content…
Cerebrovascular accident is a very serious condition in which the brain is not receiving enough oxygen to function properly. A cerebrovascular accident is also called CVA, brain attack, cerebral infarction or stroke.
A cerebrovascular accident often results in permanent serious complications and disability and is a common cause of death. Cerebrovascular accidents are the second leading cause of death worldwide and the third leading cause of death in the U.S., according to the American Heart Association.
The brain requires a steady supply of oxygen in order to pump blood effectively to all of the body. Oxygen is supplied to the brain in the blood that flows through arteries. In a cerebrovascular accident, one or more of these arteries becomes blocked or ruptures or begins to leak. This deprives a portion of the brain of vital oxygen-rich blood. This damage can become permanent within minutes and result in the death of the affected brain tissue. This is called cerebral necrosis.
There are two types of cerebrovascular accidents. An ischemic cerebrovascular accident occurs when a brain artery has been blocked. A hemorrhagic cerebrovascular accident occurs when an artery ruptures
