Anatomical terms of muscle |
The arytenoid muscle /ærɪˈtiːnɔɪd/ or interarytenoid muscle is a composite intrinsic muscle of the larynx, consisting of a transverse part and an oblique part - the two parts may be considered as separate muscles: an unpaired transverse arytenoid muscle, and a bilaterally paired oblique arytenoid muscle. [1]
The two constituent parts differ in their attachments, structure and actions. Both receive motor innervation from the recurrent laryngeal nerve(s) (each nerve being a branch of one vagus nerve (CN X)). [1]
Function of the arytenoid muscle is a good method to determine function of the recurrent laryngeal nerve. [2] Continuous electromyography of the arytenoid muscle can provide confidence to surgeons that the recurrent laryngeal nerve is not damaged during neck surgeries, such as thyroidectomy. [2]
The arytenoid muscle is found in many animals, including dogs. [3]
