    internal maxillary, superficial temporal, and transverse facial arteries. The branches run in different directions. Coursing mesially are the superior thyroid (S.T.A), a combined lingual and external maxillary trunk (L.F.T), transverse facial and internal maxillary arteries. Running laterally is the occipital artery (O.A.), and vertically the superficial temporal, ascending pharyngeal and parotid arteries. The superior thyroid artery (text-fig. 41, S.T.A) arises almost at the beginning of the external carotid. It describes the usual Text-figure 41. The larynx, thyroid gland and vessels of the neck. H.B : hyoid bone; O-H.M : omo-liyoid muscle; S-H.M : sterno-hyoid muscle; S.T.M : sterno-thyroid muscle; T.G: thyroid gland; T.H.M : thyro-hyoid muscles; T-M.A: tfinporo-maxillary artery; T-P.B : thymus and parathyroid; XII; hypo- glossal nerve.

It terminates by anastomosing with the thyroidea ima (T.I.A). It gives off mesial branches to the omo-hyoid, sterno-hyoid, sterno-thyroid, crico-thyroid and tliyro-hyoid muscles; and a branch enters the larynx through the thyro-hyoid interval. The lateral branches supply the thyroid gland and anastomose with branches of the middle thyroid artery. The corresponding superior thyroid vein enters the anterior facial vein. The [61]
