(ab) Epiglottic tubercle (tuberculum epiglotticum) (0. T. 



cushion of epiglottis). 



(ac) Epiglottic cartilage (cartilago epiglottica) . 



'(&) Thyreo-epiglottic ligament (ligamentum thyreoepiglotticum) (0. 



T. thyro-epiglottidean ligament), 

 (c) Hyo-epiglottic ligament (ligamentum hyoepiglotticum) (0. T. hyo- 



epiglottidean ligament). 

 Thyreoid Cartilage (Cartilago thyreoidea}. 



(a) Right and left plates (laminae [dextra et sinistra]) (0. T. ala). 



(b) Superior thyreoid notch (incisura thyreoidea superior). 



(c) Inferior thyreoid notch (incisura thyreoidea inferior). 



(d) Superior thyreoid tubercle (tuberculum thyreoideum superius). 



(e) Inferior thyreoid tubercle (tuberculum thyreoideum inferius). 



(f) Oblique line (linea obliqua). 



(g) Superior horn (cornu superius). 

 (h) Inferior horn (cornu inferius). 



(i) Thyreoid foramen (foramen thyreoideum). 



Cricothyreoid Joint (Articulatio cricothyreoidea) . 



(a) Capsule of joint (capsula articularis cricothyreoidea). 



(b) Lateral ceratocricoid ligaments (Ligg. ceratocricoidea lateralia}. 



(c) Anterior ceratocricoid ligament (Lig. ceratocricoideum anterius). 



(d) Posterior ceratocricoid ligaments (Ligg. ceratocricoidea posteriora). 

 Divide the structures connecting the thyreoid cartilage to the cricoid 



and remove the former. 



Cricoid Cartilage (Cartilago cricoidea). 



(a) Arch (arcus [cartilaginis cricoideae]) . 



(b) Lamina (lamina [cartilaginis cricoideae]). 



(c) Arytaenoid articular surface (fades articularis arytaenoidea) . 



(d) Thyreoid articular surface (fades articularis thyreoidea). 



Observe also the cricotracheal ligament (ligamentum crico- 

 tracheale). 



Corniculate Cartilage (Cartilago corniculata [Santorini]) (0. T. carti- 

 lage of Santorini). 



(a) Arycorniculate joint (synchondrosis arycorniculata) . 



(b) Corniculopharyngeal ligament (Lig. corniculopharyngeum) (0. T. 



Lig. jugale). 

 (ba) Cricopharyngeal ligament (Lig. cricopharyngeum) . 



Arytaenoid Cartilage (Cartilago arytaenoidea). 



Remove one in order to study the cartilage itself; leave the 

 other in situ for the study of the ligaments. 



(a) Tip or apex (apex [cartilaginis arytaenoideae]). 



(b) Base (basis [cartilaginis arytaenoideae]). 



(ba) Articular surface (fades articularis). 



(c) Posterior surface (fades posterior). 



(d) Medial surface (fades medialis) (0. T. internal surface). 



(e) Lateral surface (fades lateralis) (0. T. antero-external surface). 



(ea) Nodule or hillock (colliculus) . 



(eb) Arched ridge (crista arcuata). 



(ec) Triangular depression (fovea triangularis) . 



(ed) Oblong depression (fovea oblonga).
