 constitutes a marked subcutaneous prominence in the neck, 

 which receives the name of the laryngeal prominence (O.T. 

 pomum Adami). The posterior border of each lamina is thick 

 and rounded, and is prolonged, beyond the superior and 

 inferior borders of the lamina, in the form of two slender 

 cylindrical processes, termed the cornua. The superior cornu,

longer than the inferior cornu, gives attachment to the lateral 

 thyreo-hyoid ligament. The shorter, stronger inferior cornu 

 curves slightly medially. On the medial aspect of its tip there 

 is a facet which articulates with the side of the cricoid cartilage. 

 The superior border of the lamina is for the most part slightly 

 convex, and anteriorly it dips down to become continuous 

 with the margin of the superior thyreoid notch. The inferior 

 border is to all intents and purposes horizontal, but it is 

 divided by a projection, termed the inferior tubercle, into
