The arytenoid is an intrinsic muscle of the larynx. It has both oblique and transversly orientated fibres.

  • Attachments: Spans from one arytenoid cartilage to the opposite arytenoid.
  • Actions: Adduction of the arytenoid cartilages, narrowing the laryngeal inlet
  • Innervation: Inferior laryngeal nerve (branch of recurrent laryngeal)
  • Blood supply: branches of the superior and inferior thyroid arteries (laryngeal branches)
