 External carotid artery - Wikipedia, the free encyclopedia
The external carotid artery begins opposite the upper border of the thyroid cartilage, and, taking a slightly curved course, passes upward and forward, and then inclines backward to the space behind the neck of the mandible, where it divides into the superficial temporal and internal maxillary arteries.
Medial to it are the hyoid bone, the wall of the pharynx, the superior laryngeal nerve, and a portion of the parotid gland.
Lateral to it, in the lower part of its course, is the internal carotid artery.

The thoracic portion of the left common carotid artery ascends from the arch of the aorta through the superior mediastinum to the level of the left sternoclavicular joint, where it is continuous with the cervical portion.
The common carotid artery is contained in a sheath, which is derived from the deep cervical fascia and encloses also the internal jugular vein and vagus nerve, the vein lying lateral to the artery, and the nerve between the artery and vein, on a plane posterior to both.
Behind, the artery is separated from the transverse processes of the cervical vertebræ; by the Longus colli and Longus capitis, the sympathetic trunk being interposed between it and the muscles.

 Clinical Case - Upper Respiratory Tract
The lingual and pharyngeal tonsils are also lymphatic tissue; the lingual tonsil is located on the posterior aspect of the tongue and the pharyngeal tonsil, or adenoid, is found on the upper part of the posterior pharyngeal wall.
The palatine tonsil is supplied by five arterial branches: the ascending palatine and tonsillar branches of the facial artery, the palatine branch of the ascending pharyngeal artery, the dorsal lingual branch of the lingual artery, and the descending palatine branch of the maxillary artery.
The glossopharyngeal nerve accompanies the tonsillar artery on the lateral wall of the pharynx and is particularly vulnerable during a tonsillectomy.

Behind either condyle is a depression, the condyloid fossa, which receives the posterior margin of the superior facet of the atlas when the head is bent backward; the floor of this fossa is sometimes perforated by the condyloid canal, through which an emissary vein passes from the transverse sinus.

This mechanism is observed to constitute the principal "pharyngeal articulator." This interpretation views the pharyngeal stop as auditorily equivalent to what has been called a "massive glottal stop," and to what has been called an "epiglottal stop." The pharyngeal stop is represented by the IPA symbol for an epiglottal stop [ʡ].
