Anatomical terms of muscle
[edit on Wikidata]
The oblique arytenoid is bilaterally paired intrinsic muscle of the larynx. It is superficial to the transverse arytenoid; the oblique and transverse arytenoids are often considered two parts of a single muscle - the interarytenoid muscle (which is then said to have an oblique part and a transverse part).[1]
Each oblique arytenoid muscle attaches to both arytenoid cartilages; the two oblique arytenoids thus cross each other.[1]
Some muscle fibres of the oblique arytenoid muscle proceed to extend laterally around the apex of arythenoid cartilage into the aryepiglottic fold, thus forming the aryepiglottic muscle.[1]
