It lies opposite the disc between the fifth and sixth cervical vertebræ, and at this level the common carotid artery may be compressed against the _carotid tubercle_ on the transverse process of the sixth cervical vertebra.
Experts consider this condition, called carotid intima media thickness, a precursor to heart attacks and strokes.
However, the prevention-cure equation gets a bit more complicated when considering a stroke-preventing surgery called carotid endarterectomy.
Carotid ultrasound looks for atherosclerosis in the neck arteries and a blockage condition called carotid stenosis.
He had a what's called carotid endarterectomy where they slice out the carotid artery and scrape out the plaque.
There's also two blood vessels up here called the carotid artery, which supply blood through the brain and sometimes they can get a little blockage in them as well.
The Achieve study was using imaging technology known as carotid intima-media thickness, or CIMT, a non-invasive ultrasound test.
This intrinsically important discovery is of all the more interest in view of Hering's discovery (1923-1924) that the area known as the carotid sinus, on the internal carotid at its junction with the common carotid artery, has an analogous function to that of the areas in the aorta from which the depressor nerves arise.
It becomes as necessary, therefore, in the performance of surgical operations upon the subclavian artery, to fix the clavicle by depressing it, as in Plate 8, as it is to give fixity to the lower maxilla and larynx, in the position of Plate 7, when the carotid is the subject of operation.
The first of these, or carotid trunk (1), ends in an enlargement (a) termed the carotid gland, of spongy structure, which gives rise to two arteries, one the lingual (l), the other (c) the carotid which goes to the head and brain.
