− | Fusion of the two plates of the thyroid cartilage is incomplete forming a rostral pointing notch which is a good site for surgical entry into the larynx. The '''thyroarytenoid muscle''' is divided into 2 parts; the '''rostral''' and '''caudal vocalis''', which are situated within the vocal folds and vestibular folds. The '''cuneiform processes''' are attached to the [[Epiglottis|epiglottis]]. | + | Fusion of the two plates of the thyroid cartilage is incomplete forming a rostral pointing notch which is a good site for surgical entry into the larynx.

− | The '''thyroid cartilage''' in ruminants is completely ventral. A small median ventricle is present in sheep and goats. There is a narrow glottic cleft, making intubation difficult. The larynx is close to the median '''retropharyngeal lymph node''', so enlargement of the lymph nodes may compress the larynx as well as the [[Pharynx - Anatomy & Physiology|pharynx]]. | + | The '''thyroid cartilage''' in ruminants is completely ventral.

− | There are no vocal folds in avian species. Sound in the bird is produced in the [[Syrinx - Anatomy & Physiology|syrinx]]. The larynx is on the [[Hyoid Apparatus - Anatomy & Physiology|hyoid apparatus]]. There are paired arytenoids, one constrictor and one dilator muscle only.
