Muscle Origin Insertion Action Nerve
aryepiglotticus arytenoid cartilage apex epiglottis (lateral border) assists in closure of additus of larynx vagus nerve (CN X, recurrent laryngeal branch)
cricrothyroid cricoid cartilage (anterolateral aspect) thyroid cartilage (inferior cornu & lower laminar) lengthens & tenses vocal cords by tilting thyroid cartilage forwards (increases pitch of sound) vagus nerve (CN X, superior laryngeal)
cricoarytenoid cricoid cartilage (posterior aspect) arytenoid cartilage (muscular process) abduction & lateral rotation arytenoid cartilage (opens rima glottidis) vagus nerve (CN X, recurrent laryngeal branch)
oblique arytenoid arytenoid cartilage (muscular process) superior pole of opposite arytenoid cartilage adduction of arytenoid cartilages (closes rima glottidis ) vagus nerve (CN X, recurrent laryngeal branch)
lateral cricoarytenoid cricoid cartilage (lateral aspect of arch) arytenoid cartilage (muscular process) adduction & medial rotation of arytenoid cartilage (closes rima glottidis) vagus nerve (CN X, recurrent laryngeal branch)
thyro-arytenoid & vocalis thyroid cartilage (lower posterior surface of angle between laminae) arytenoid cartilage (vocal process) shortens & relaxes vocal cords by medial rotation & protraction of arytenoid cartilage (lowers pitch of sound) vagus nerve (CN X, recurrent laryngeal branch)
thyro-epidlotticus & vocalis thyroid cartilage (lower posterior surface) epiglottis (lateral border) assists in closure of additus to larynx vagus nerve (CN X, recurrent laryngeal branch)
transverse arytenoid arytenoid cartilage (posterior surface & muscular process) corresponding surfaces of opposite side arytenoid cartilage adduction arytenoid cartilage (closes rima glottidis) vagus nerve (CN X, recurrent laryngeal branch)
