... tissues of the larynx were traced manually in CT scans. This approach provided outlines of the cartilaginous framework and the airway. Derived 3D surfaces of eight specimens from each of the 6 species have been archived at Morphobank (O'Leary, Kaufman 2012), project # P4106. Coronal histological...

... in laryngeal physiology in X. borealis suggest a selective loss of hormonal regulation of these features while leaving hormonal regulation of other features (such as overall larynx size) intact. Xenopus muelleri presents an intermediate phenotype, in that sex differences in EMG potentiation and laryngeal...

... to explore the anatomy of the larynx and soft palate in the harbour seal ( Phoca vitulina ), and generate models for how valving mechanisms in the head and neck may function during breathing, phonating, diving and swallowing. Harbour seals have an elevated larynx and the epiglottis may rise above the level...

...Tobias Riede; Zhiheng Li; Isao T. Tokuda; Colleen G. Farmer ABSTRACT Sauropsid vocalization is mediated by the syrinx in birds and the larynx in extant reptiles; but whereas avian vocal production has received much attention, the vocal mechanism of basal reptilians is poorly understood...

... . The de-masculinization of these laryngeal features suggests an alteration in sensitivity to the gonadal hormones that are known to control the sexual differentiation of the larynx in other Xenopus and Silurana species.

... to the larynx. Toothed cetaceans (Odontoceti) are capable of producing sounds at depth, either for locating prey or for communication. It has been suggested that during dives, air from the lungs and upper respiratory tract can be moved to the vestibular and nasal cavities to permit sound generation to continue...

... frequency and the volume of the whole larynx and ear. This is also the case for call pulse rate, indicating that for this species both spectral and temporal call parameters are biomechanically related to laryngeal size which is, in turn, largely mediated by body size. General body size effects might also...
