La arteria lingual es una arteria de la región de la cabeza y el cuello. Es la tercera rama principal de la arteria carótida externa. Es responsable de la irrigación sanguínea de la lengua y el suelo de la boca.

Learn More Trayecto La arteria lingual se origina en la cara anteromedial de la arteria carótida externa, a la altura del hueso hioides (C3). Asciende medialmente a lo largo de la superficie del músculo constrictor medio de la faringe. A continuación, pasa por detrás del nervio hipogloso, el músculo estilohioideo y el vientre posterior del músculo digástrico. La arteria lingual penetra en la lengua pasando por debajo del músculo hiogloso. Termina dividiéndose en ramas linguales profundas y sublinguales dentro de la sustancia de la lengua.

Irrigación La arteria lingual irriga las estructuras de la cabeza y el cuello a través de cuatro ramas principales: Rama suprahioidea: irriga los músculos suprahioideos del cuello. Ramas linguales dorsales: irrigan la parte posterior de la lengua, el paladar blando, la amígdala palatina y la epiglotis. Rama sublingual: irriga la glándula sublingual, el músculo milohioideo y el suelo de la boca. Rama lingual profunda: irriga la lengua.

The lingual artery is primarily responsible for supplying blood to the tongue and the floor of the mouth. It ensures that these structures receive adequate oxygen and nutrients for proper function. Where does the lingual artery originate? The lingual artery arises from the anteromedial aspect of the external carotid artery at the level of the hyoid bone (C3). This positioning is crucial for its pathway towards the tongue. What structures are irrigated by the branches of the lingual artery? The lingual artery has four main branches that supply various structures: the suprahyoid muscles, the posterior part of the tongue, the sublingual gland, and the deep tissues of the tongue. Each branch plays a vital role in the vascularisation of the head and neck. How does the lingual artery travel through the neck? After its origin, the lingual artery ascends medially alongside the middle pharyngeal constrictor muscle and passes behind the hypoglossal nerve, the stylohyoid muscle, and the posterior belly of the digastric muscle. It then enters the tongue beneath the hyoglossus muscle. What clinical significance does the lingual artery have? The lingual artery is clinically significant due to its role in supplying critical structures in the oral cavity, making it important during surgical procedures involving the tongue and floor of the mouth. Understanding its anatomy helps prevent complications during such interventions. Valora este artículo
