Clinicals
1. The most common location for atherosclerotic plaque formation is at the bifurcation or branch points of arteries, in the case of the carotid arteries
2. bruit is a systolic murmur heard only in the neck arteries
3. Tracheostomy a surgical procedure to create an opening through the neck into the trachea
4. Carotid sinus syndrome
