Definition
The arytaenoideus obliquus muscle is a paired muscle belonging to the internal laryngeal musculature.
Course
Originating from the basal third (processus muscularis) of the cartilago arytaenoidea, the arytaenoideus obliquus muscle runs obliquely to the upper third of the arytenoid cartilage (apex cartilaginis arytaenoideae) of the opposite side. From there, further fibres radiate into the plica aryepiglottica, where they are addressed as the aryepiglotticus muscle.
Innervation
Innervation is provided by the terminal branch of the recurrent laryngeal nerve, the inferior laryngeal nerve.
Function
The traction of the arytaenoideus obliquus muscle constricts the pars intercartilaginea by approximating and tilting inwards the two arytenoid cartilages.
