Laryngeal artery: Difference between revisions

Latest revision as of 20:07, 6 March 2025

The laryngeal artery refers to the arteries that supply blood to the larynx. There are two main laryngeal arteries: the superior thyroid artery and the inferior thyroid artery.

Superior Laryngeal Artery[edit]

The superior laryngeal artery is a branch of the superior thyroid artery. It accompanies the internal laryngeal nerve and supplies the larynx above the vocal cords.

Inferior Laryngeal Artery[edit]

The inferior laryngeal artery is a branch of the inferior thyroid artery. It accompanies the recurrent laryngeal nerve and supplies the larynx below the vocal cords.

Function[edit]

The laryngeal arteries are crucial for providing oxygenated blood to the larynx, which is essential for its function in voice production and breathing.

Clinical Significance[edit]

Damage to the laryngeal arteries can lead to ischemia of the laryngeal tissues, potentially affecting voice and airway function. Surgical procedures involving the thyroid gland or the neck must take care to preserve these arteries to prevent complications.

+The '''laryngeal artery''' refers to the arteries that supply blood to the [[larynx]]. There are two main laryngeal arteries: the '''[[superior thyroid artery]]''' and the '''[[inferior thyroid artery]]'''.
-The '''Laryngeal artery''' is a branch of the [[superior thyroid artery]] that supplies blood to the [[larynx]]. It is a vital component of the [[circulatory system]] in the neck and throat region.
+== Superior Laryngeal Artery ==
+The [[superior laryngeal artery]] is a branch of the [[superior thyroid artery]]. It accompanies the [[internal laryngeal nerve]] and supplies the [[larynx]] above the [[vocal cords]].
-==Anatomy==
+== Inferior Laryngeal Artery ==
+The [[inferior laryngeal artery]] is a branch of the [[inferior thyroid artery]]. It accompanies the [[recurrent laryngeal nerve]] and supplies the [[larynx]] below the [[vocal cords]].
-The laryngeal artery originates from the superior thyroid artery, which is a branch of the [[external carotid artery]]. It travels downwards and medially to reach the larynx, where it divides into several smaller branches. These branches supply blood to the various structures of the larynx, including the [[vocal cords]], [[epiglottis]], and [[thyroid cartilage]].

+Damage to the laryngeal arteries can lead to [[ischemia]] of the laryngeal tissues, potentially affecting [[voice]] and [[airway]] function. Surgical procedures involving the [[thyroid gland]] or the [[neck]] must take care to preserve these arteries to prevent complications.
-The primary function of the laryngeal artery is to supply oxygenated blood to the larynx. This is crucial for the normal functioning of the larynx, which plays a key role in breathing, swallowing, and voice production.
