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.

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.

The muscles that open a crocodile or alligator's jaws are weak in comparison to the ones used to close their jaws. So, based on that very short answer, it is indeed possible for you to hold an alligator's mouth shut. You can easily hold a crocodile's mouth shut providing you can get into the right position to do so.

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 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.

. 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.

Crocodile Bites On Humans

Anatomy of the Jaw: The muscles that power the alligator's jaw are incredibly developed, particularly the adductor muscles responsible for closing the mouth. These muscles are densely packed and give the jaw its phenomenal closing power. Interestingly, while their closing power is immense, the muscles that open the jaw are much weaker.

Jaw Muscles: Alligator vs. Crocodile. Both alligators and crocodiles have incredibly strong jaw muscles, and they are capable of exerting an enormous amount of force when they bite down on something. However, there are some differences in the structure of their jaw muscles that are worth noting. Alligators have a more massive jaw muscle mass.
