Stroke (also known as a cerebrovascular accident ( CVA) or brain attack) is a medical condition in which poor blood flow to the brain causes cell death. [ 5] There are two main types of stroke: ischemic, due to lack of blood flow, and hemorrhagic, due to bleeding. [ 5] Both cause parts of the brain to stop functioning properly.
There are two types of strokes, according to the National Institutes of Health: Ischemic stroke happens when blood clots or plaque block blood vessels to the brain. About 87% of strokes are ...
In high school, collegiate, and Olympic swimming, there are two undulating strokes (breaststroke and butterfly stroke) and two alternating strokes (front crawl and backstroke). Most strokes involve rhythmic and coordinated movements of all major body parts — torso, arms, legs, hands, feet, and head. Breathing typically must be synchronized ...
Cerebrovascular disease includes a variety of medical conditions that affect the blood vessels of the brain and the cerebral circulation. Arteries supplying oxygen and nutrients to the brain are often damaged or deformed in these disorders. [2] The most common presentation of cerebrovascular disease is an ischemic stroke or mini-stroke and ...
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes of the piston (one up and one down movement) in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle in two crankshaft revolutions.
Cerebral infarction, also known as an ischemic stroke, is the pathologic process that results in an area of necrotic tissue in the brain (cerebral infarct). [ 1] In mid to high income countries, a stroke is the main reason for disability among people and the 2nd cause of death. [ 2]
Brain ischemia is a condition in which there is insufficient bloodflow to the brain to meet metabolic demand. [ 1] This leads to poor oxygen supply or cerebral hypoxia and thus leads to the death of brain tissue or cerebral infarction / ischemic stroke. [ 2] It is a sub-type of stroke along with subarachnoid hemorrhage and intracerebral hemorrhage.
Strokes that connect, as in A and H, or cross other strokes, as in t, are also known as crossbars. [9] A longer horizontal stroke at the top or bottom, as in E T, is an arm. [4] The junction of two strokes intersecting above as in A M X x is an apex and the joining of two strokes intersecting below as in V W v w is a vertex. [10]
