carotisk

Carotisk, also known as carotid, refers to the carotid arteries, which are major blood vessels in the neck that supply blood to the brain, neck, and face. There are two primary carotid arteries: the right and the left. Each originates from different parts of the cardiovascular system; the right carotid artery typically arises from the brachiocephalic artery, while the left originates directly from the aortic arch.

The carotid arteries bifurcate into two branches: the internal carotid artery, which primarily supplies blood to the brain, and the external carotid artery, responsible for blood flow to the face and scalp. The internal carotid artery enters the skull through the carotid canal and contributes to the circle of Willis, a critical network of arteries that ensures blood flow to the brain.

Clinically, the carotid arteries are significant due to their association with cerebrovascular diseases. Carotid artery stenosis, the narrowing of these vessels often caused by atherosclerosis, is a leading risk factor for ischemic stroke. Detection typically involves ultrasound imaging, angiography, or other diagnostic tools.

The carotid pulse is commonly used in medical examinations to assess cardiovascular health. Palpating the carotid artery provides information about heart rate and rhythm. In emergencies, rapid assessment of carotid pulse can be critical for evaluating circulation.

Understanding the anatomy and function of the carotid arteries is essential in both medical diagnosis and treatment of vascular conditions affecting the head and brain. Preventive measures focus on managing risk factors such as hypertension, smoking, and high cholesterol to maintain healthy carotid arteries and reduce cerebrovascular risk.
