Stroke | Nucleus Health

A stroke occurs when the blood flow in part of your brain is blocked. After just a few minutes, the starved brain cells begin to die. Normally, the brain receives blood via two major pairs of arteries, which branch throughout brain tissue, and supply your brain cells with a constant flow of oxygen, glucose, and …

Craniotomy and Craniectomy

Your doctor may recommend a craniotomy or craniectomy procedure to treat a number of different brain diseases, injuries, or conditions. Your skull is made of bone, and serves as a hard, protective covering for your brain. Just inside your skull, three layers of tissue called meninges surround your brain. The thick, outermost layer is the …

Baroreflex Regulation of Blood Pressure, Animation.

Baroreflex, or baroreceptor reflex, is one of the mechanisms the body uses to maintain stable blood pressure levels or homeostasis. Baroreflex is a rapid negative feedback loop in which an elevated blood pressure causes heart rate and blood pressure to decrease. Reversely, a decrease in blood pressure leads to an increased heart rate, returning blood …

Endovascular Coiling for Brain Aneurysm, Animation.

Endovascular Coiling for Brain Aneurysm, Animation.

Endovascular coiling or endovascular embolization is a minimally invasive technique performed to treat brain aneurysms. The goal of the treatment is to block blood flow into the aneurysm and therefore reduce the risk of aneurysm rupturing. In this procedure, a catheter guided by a wire is inserted through the femoral artery at the groin and …

Cardiac Output, Stroke volume, EDV, ESV, Ejection Fraction

Cardiac Output, Stroke volume, EDV, ESV, Ejection Fraction

CARDIAC OUTPUT is the amount of blood pumped by each ventricle in one minute. It is the product of STROKE VOLUME – the amount of blood pumped in one heartbeat, and HEART RATE – the number of beats in one minute. An INcrease in either stroke volume or heart rate results in INcreased cardiac output, …
