The Arytenoideus muscle occupies the posterior concave surface ofthe arytenoid cartilages, between which it is stretched.

The Thyro-epiglottideus appears to be formed by the upper fibres ofthe thyro-arytenoideus muscle : they spread out upon the externa] sur-face of the sacculus laryngis and in the aryteno-epiglottidean fold ofmucous membrane, in which they are lost: a few of the anterior fibresbeing continued onwards to the side of the epiglottis. The Aryteno-epiglottideus superior consists of a few scattered fibres,which pass forwards in the fold of mucous membrane forming thelateral boundary of the entrance into the larynx, from the apex of thearytenoid cartilage to the side of the epiglottis.
