Anatomical characteristics of the larynx in giraffe (Giraffa camelopardalis)

In the present study, the most outstanding anatomical findings of the larynx of a giraffe are described. The larynx obtained from a male necropsied animal was studied following fixation in a 10% formaldehyde solution. There was no rostral horn in the thyroid cartilage and so cranial thyroid fissure was almost smooth or hardly visible concave structure. Caudal horn was short and caudal thyroid fissure was very depth. Lateral surface of arytenoid cartilage possessed a well-developed oblique arcuate crest between corniculate and vocal processes. On the mucosa of corniculate cartilage, aryepiglottic fold and laryngeal ventricle, there were many macroscopically observable rounded projections in different sizes. There were no cuneiform cartilages in both lateral side of the base of epiglottis. The anatomy of the larynx and its components in the giraffe and horse, showed little differences and overall their laryngeal morphological features were similar.
