The ceratocricoid muscle.
One hundred and thirty-four hemilarynges were examined for the presence of the ceratocricoid muscle. This muscle arises from the cricoid cartilage, below the posterior cricoarytenoid muscle, and inserts onto the posterior aspect of the inferior horn of the thyroid cartilage. A prevalence of 6.3% was found. The anatomy, relations and innervation of the muscle are discussed.
