... rhythmic mandibular jaw and hyobranchial (tongue) movements. Chewing occurs in chondrichthyans (sharks and rays), actinopterygians (ray-finned fishes), dipnoi (lungfishes) as well as amniotes and involves similarities in the patterns of muscle activity and movement of the feeding apparatus. It has been...

...Roderick A. Suthers; John R. Rothgerber; Kenneth Kragh Jensen ABSTRACT Lingual articulation in humans is one of the primary means of vocal tract resonance filtering that produces the characteristic vowel formants of speech. In songbirds, the function of the tongue in song has not been thoroughly...

... muscles. Several previously unknown features of the laryngeal aditus (glottis) are described and their functional significance in its opening and closure are considered. The tongue plays an essential part in producing and maintaining closure during dives and feeding bouts. Closure is brought about...

... of the tongue in some lizard taxa are thought to be associated with the evolution of vomerolfaction as the main prey detection mode. Moreover, specializations of the tongue are hypothesized to compromise the efficiency of the tongue during transport; thus, driving the evolution of inertial transport. Here we...

... with the movements of each system have been investigated in detail independently, the actual integration between the two systems has received less attention. Recently, the independence of the movements of the jaw and locomotor systems was reported during tongue-based prey capture in an iguanian lizard ( Anolis...

... energetics biomechanics tongue Suction feeding is the primary modality by which insects ingest a liquid diet and requires a tightly sealed proboscis, along with one or several fluid pumps ( Borrell and Krenn, 2006 ; Kingsolver and Daniel, 1995 ). In many insect taxa, the fluid pump is formed from...

... Balaena mysticetus water flow buccal cavity baleen tongue feeding mechanism morphology filtration flow hydrodynamics Balaenid (bowhead and right) whales are continuous filter feeders, in which a steady current of prey-laden water enters the mouth anteriorly between paired racks of baleen...

...Stephen M. Deban; Ursula Dicke SUMMARY Salamanders of the genus Hydromantes project their tongues the greatest distance of any amphibian to capture prey, up to 80% of body length or approximately 6 cm in an adult individual. During tongue projection on distant prey, the tongue is shot ballistically...

...Jurriaan H. de Groot; Inke van der Sluijs; Peter Ch. Snelderwaard; Johan L. van Leeuwen SUMMARY The forked snake tongue is a muscular organ without hard skeletal support. A functional interpretation of the variable arrangement of the intrinsic muscles along the tongue requires a quantitative...

...Timothy K. Baker; Karina Rios; Stanley D. Hillyard SUMMARY The dorsal lingual epithelium from the tongue of the toad Bufo marinus was mounted in an Ussing-type chamber, and the short-circuit current ( I sc ) was measured using a low-noise voltage clamp. With NaCl Ringer bathing the mucosal...

...Kiisa C. Nishikawa; William M. Kier; Kathleen K. Smith ABSTRACT The goal of this study was to investigate morphological adaptations associated with hydrostatic elongation of the tongue during feeding in the African pig-nosed frog Hemisus marmoratum . Whereas previous studies had suggested...

... from that of other frogs that have been studied. During feeding in H. marmoratum , the tongue ‘telescopes’ straight out of the mouth, as opposed to the ‘flipping’ tongue trajectory observed in most other frogs. At the time of prey contact, two lateral lobes of tissue at the tongue tip envelop the prey...

...Peter C. Wainwright; Albert F. Bennett ABSTRACT In this paper we document the activity of key muscles of the tongue, hyobranchia! apparatus and head during prey capture in the lizard Chamaeleo jacksonii Boulenger and use these data to test current hypotheses of chameleon tongue function...
