What else can I help you with?
What is mild vascular ischemia?
a decrease in bloodflow to the brain due to narrowing of the arteries
Explain what an unheathly lifestyle can do to your coronary arteries?
it will cause deposition of cholesterol in the artery, narrowing it's lumen and may lead to ischemia, and worst obstruction may lead to myocardial infarction.
What is cerebral ischemia?
Focal cerebral ischemia (FCI) is often results from a blood clot in the brain. The blood flow in the affected area is reduced. The reduction could be severe or mild but usually FCI causes irreversible injury to sensitive neurons.
What is the most common area of ischemia in the brain?
basal ganglia
What kinds of health problems can be caused by blockages in coronary arteries?
Myocardial ischemia or infarction. (Heart attack)
What is the path of blood from the left ventricle to the brain?
Blood vessels that supply the brain are the two carotid arteries and the two vertebral arteries.- From the left ventricle, blood flows into the aorta and the common carotid arteries supply the frontal portion of the brain through the inner carotid arteries, which lead to blood vessels such as the three pairs of cerebral arteries (anterior, middle, posterior).- From the left ventricle, blood flows from the arch of the aorta into the paired subclavian arteries, and then to the vertebral arteries, which supply the rear and lower parts of the brain through the basilar artery (which ends at the posterior cerebral arteries).* Within the brain, cross-connections between these arteries (called the Circle of Willis) provide some redundancy should any of the arteries become severed or blocked.
What is Ischemia Disorder?
Lack of oxygen , in mental illness, specifically to the brain.
What is the term for decreased blood supply?
Ischemia is the medical term meaning decreased blood supply. Prolonged ischemia can lead to infarction.
What two paired arteries enter the skull to supply the brain?
The anterior portions of the brain are supplied by the internal carotid arteries. The posterior portion of the brain is supplied by the vertebral arteries.
Provides the brain with oxygen and nutrients?
Oxygen and nutrients are provided to the brain via the carotid arteries and vertebral arteries.
What is the medical term meaning insufficient blood supply to head?
The medical term for insufficient blood supply to the head is cerebral ischemia. This condition can lead to a lack of oxygen and nutrients reaching the brain, causing symptoms such as dizziness, confusion, and in severe cases, stroke. Treatment typically involves restoring blood flow to the affected area to prevent further damage.
Results when brain region is deprived of blood or exposed to prolonged ischemia?
Stroke or Death
