phagus. Ics anterior surface, somewhat convex, is attached to 



the tongue, by the glosso-epiglottidean ligaments, and to the hyoid 



hone by the hyo-epiglottidean muscle. 



The posterior surface is rough, and 



studded with numerous mucous glands. 



The base articulates with the posterior 



part of the body of the thyroid. 



The apex is free, and somewhat curved 



forwards. From the base of the epiglottis, 



two lateral processes extend backwards : 



these are the cunieforTii cartilages, and

LARYNGEAL LIGAMENTS. 



The ligaments connected with the larynx are extrinsic and 

 intrinsic. The extrinsic ones are as follows : — 



Lateral Hyo-thyroid. I Hyo-epiglottidean. 



Middle Hyo-thyi'oid. I Crico-trachealis. 



The later al-hyo- thyroid pass from the superior border of the 

 thyroid cartilage to the heel process of the os hyoides. The 

 ■middle hyo-thyroid ligament is a broad membrane, filling up the 

 space between the anterior border of the thyroid cartilage and the 

 lieels and body of the os hyoides. The hyo-einglottidean ligament 

 is a band of yellow elastic tissue, running between the base of the 

 epiglottis and body of the os hyoides, covered by the hyo-epiglotti- 

 dean muscle. The crico-trachealis ]o\x\^ the cricoid cartilage to 

 the trachea. 



The intrinsic ligaments are : — 



Thyro-epiglottidean. i Crico-arytenoideau. 



Arytenoidean. | Crico-thyroideau. 



Thyro-arytenoideau. 



The thyro-epiglottidean ligament binds the base of the epi- 

 glottis to the superior border of the thyroid cartilage. The 

 -arytenoidean ligament joins the two arytenoid cartilages together.
