Alligator jaw musculature, like that of other vertebrates, is three-dimensionally complex and difficult to illustrate in two-dimensional media. Here we provided the first volumetric model of Alligator, and crocodylian musculature based on raw imaging data. This downloadable, 3D model of Alligator jaw muscles, skull and nervous tissues shows the. The Caiman crocodilus , popularly known as alligator , is a species of crocodilian, which has a crest or "forehead" described as "in crescent shape", observed, immediately, dorsal in relation to.

PMID: 23762228 PMCID: PMC3676386 DOI: 10.1371/journal.pone.0062806 Abstract Modern imaging and dissemination methods enable morphologists to share complex, three-dimensional (3D) data in ways not previously possible. Here we present a 3D interactive model of the jaw musculature of the American Alligator (Alligator mississippiensis). . The total bite force, in each place of the jaw, is obtained by adding the modulus of all reaction forces at the fixed points for simultaneous measurement (Taborda et al. 2021). A similar FEA. We expect these imaging data will facilitate numerous new avenues of investigation, including tracking the development and ontogeny of alligator jaw muscles (Figure 9b), their functional relationships with the skull, and how to best estimate muscle physiology in extinct crocodyliform species during behaviors like jaw closing (Figure 9c). Figure 3. The 3D model of the jaw muscles of Alligator mississippiensisshowing the relationship between the skull, muscles and branches of the trigeminal nerve. Left: with skull; Right: skull removed.

Finally, we compare 3D resultants of jaw muscles of the hard-biting species in our sample (A. mississippiensis, T. rex, P. erithacus) to illustrate how disparate jaw muscle resultants are employed. Using Iodine-contrast enhanced microCT imaging, a segmented model of jaw muscles, trigeminal nerve, brain and skull are presented as a cross-sectional atlas and 3D, interactive pdf of the rendered. The cartilago transiliens is a fibrocartilaginous structure within the jaw muscles of crocodylians. The cartilago transiliens slides between the pterygoid buttress and coronoid region of the lower jaw and connects two muscles historically identified as m. pseudotemporalis superficialis and m. intramandibularis. Department of Geology, Texas Christian University, Ft. Worth 76129. The architecture of the jaw muscles and their tendons of Alligator mississippiensis is described and their function examined by electromyography. Alligator grabs its prey with forward lunges or rapid lateral movements of the head. It does not engage in regular masticatory cycles.

The architecture of the jaw muscles and their tendons of Alligator mississippiensis is described and their function examined by electromyography.Alligator grabs its prey with forward lunges or rapid lateral movements of the head. It does not engage in regular masticatory cycles. Prey is manipulated by inertial movements and the tongue does not appear to play any role in transport.
Alligator jaw muscles have little strength for opening their mouth, but the muscles that shut them are very strong and have awesome force, about 300 pounds per square inch in an adult. Alligators do not require as much food as we do. In the summer a large alligator may only eat once or twice a week. A mature alligator has 80 conical shaped teeth. How Powerful Are Alligator's Jaws? (Explanation Revealed!) According to a study published in the Journal of the American Medical Association, the muscles that shut the alligator jaw are very strong and have awesome force, which is about 300 pounds per square inch.

An average adult American alligator's weight and length is 360 kg (790 lb) and 4 m (13 ft), but they sometimes grow to 4.4 m (14 ft) long and weigh over 450 kg (990 lb). [10] The largest ever recorded, found in Louisiana, measured 5.84 m (19.2 ft). [11] The Chinese alligator is smaller, rarely exceeding 2.1 m (7 ft) in length. Image Source An Alligator is a crocodilian in the genus 'Alligator' of the family 'Alligatoridae'. Alligators are large, semi-aquatic carnivorous reptiles with four small legs and a very large, long tail. The tail is half the animals total length.
