Carotid stenosis occurs when fatty deposits, or plaques, block the carotid arteries — the blood vessels that deliver blood to your brain and head. The blockage increases stroke risk.

How many branches does the carotid triangle have?
Within the carotid triangle it gives five branches ( superior thyroid, lingual, facial, occipital and ascending pharyngeal). It leaves the carotid triangle by passing deep to posterior belly of digastric and stylohyoid muscles.
Which gland divides into two terminal branches?
Within the parotid gland it give one more branch ( posterior auricular) and finally it terminates at the level of neck of mandible within the parotid gland by dividing into its two terminal branches viz. maxillary and superficial temporal arteries.
Where is the external carotid artery located?
One of the major sources of oxygen-rich blood to the head, the external carotid artery is the smaller of the two arteries that arise at the terminal end of the common carotid artery, near the upper border of the larynx at each side of the neck. On both sides, these arteries run upwards and slightly to the front, before curving backward to reach the space behind the upper portion of the mandible, or jawbone.
What is the function of the carotid artery?
As such, and along with its many branches, it plays an essential role in delivering oxygenated blood to the face, scalp, tongue, upper and lower teeth, gums, sinus, external and middle ear, pharynx, larynx, as well as the thyroid.
What is the common origin of the lingual and facial arteries?
Linguofacial trunk : A common origin of the lingual and facial arteries, this occurs in about 20% of cases. Thyrolingual trunk: This is when the superior thyroid and lingual arteries arise at the same location and occurs in about 2.5% of cases.
What are the consequences of a ruptured carotid artery?
Rupture due to an injury can lead to permanent disability or death. Carotid artery disease, due to partial or total blockage of blood flow, is the leading cause of stroke.
Which artery runs from the middle of the neck to the space behind the upper mandible?
As the external carotid artery runs its course from the middle of the neck to the space behind the upper mandible, it becomes progressively smaller and gives off a number of branches. The branches of the external carotid artery include: Superior thyroid artery: The origin of the super laryngeal artery, which supplies the larynx, ...
Which artery supplies the larynx?

Which artery supplies the neck, face and head?
The external carotid arter y (ECA) is one of the two terminal branches of the common carotid artery that has many branches that supplies the structures of the neck, face and head. The other terminal branch is the internal carotid (ICA), which is somewhat larger than the ECA, which supplies the intracranial structures.
What gland gives rise to terminal branches?
Along its course, it rapidly diminishes in size and as it does so, gives off various branches (see below). As it enters the parotid gland , it gives rise to its terminal branches, the superficial temporal and maxillary arteries.
