  • AVE at 10 Hz produced deep masseter muscle relaxation and finger warming within six minutes.
  • Unlike hystricomorphous and myomorphous rodents, the medial masseter muscle does not pass through the infraorbital canal.
  • The masseter muscle does attach directly behind the zygomatic arch in a manner very different from sciuromorphs.
  • Here the nerve stimulator can be used in identifying the donor motor nerve to the masseter muscle.
  • The skull is protrogomorphous; it has no specialized attachments for the masseter muscles as seen in other rodents.
  • A sciuromorphous zygomasseteric system is characterized by attachment of the lateral masseter muscle along the side of the rostrum.
  • The infraorbital canal is enlarged, presumably allowing for the passage of the medial masseter muscle as with other hystricomorphs.
  • Conversely, while a masseter muscle can be large due to congenital reasons, it can commonly be an acquired deformity.
  • The parotid duct, a long excretory duct, emerges from the front of each gland, superficial to the masseter muscle.
  • The insertion joins the masseter muscle to form a common tendinous sling which allows the medial pterygoid and masseter to be powerful elevators of the jaw.
  • -Masseter muscle is compartmentalized by a laminar structure, which was shown to elevate Tnmd mRNA in mouse embryos between E12.5 to E17.5, which further decreased after birth.
  • These may include the thick muscle in the cheek that closes the jaw ( masseter muscle ) and the broad muscle that draws back the lower jaw and closes the mouth ( temporalis muscle ).
  • This typically involves the masseter muscle and the anterior portion of the temporalis ( the large outer muscles that clench ), and the lateral pterygoids, relatively small bilateral muscles that act together to perform sideways grinding.
  • Due to its smaller mouth, body anatomy, and masseter muscle, it tends to concentrate on food items up to 3 ( cm ) in diameter, while larger species eat items up to 6 ( cm ) in diameter.
  • This condition is found in the Muroidea ( Myomorpha ) and most Gliridae ( Sciuromorpha : in the latter it is often referred to as pseudomyomorphy ) . suggest that the infraorbital foramen of the extinct sciurid subfamily Cedromurinae may have allowed for the passage of the masseter muscle.
  • The Hystricomorpha, such as the guinea pig, have larger superficial masseter muscles and smaller deep masseter muscles than rats or squirrels, possibly making them less efficient at biting with the incisors, but their enlarged internal pterygoid muscles may allow them to move the jaw further sideways when chewing.
  • The Hystricomorpha, such as the guinea pig, have larger superficial masseter muscles and smaller deep masseter muscles than rats or squirrels, possibly making them less efficient at biting with the incisors, but their enlarged internal pterygoid muscles may allow them to move the jaw further sideways when chewing.
  • Scientific criticism points out that the lips of modern cats, especially larger species, display incredible elasticity and the usual lip length would stretch suitably, despite the larger degree of opening, and that in living carnivores the lip line is always anterior to the masseter muscle, which in " Smilodon " was located just behind the carnassials.
  • Otherwise it can be assumed that their anatomy was generally not as specialized as that of his later relatives, but it had carnassial teeth to process more effectively meat and flat fangs, located just below the nose, without being cross-rounded as in other un-specialized mammal carnivores, while the accommodation area of the masseter muscle ( involved in the movements of the jaw ) was reduced.
  • Bruising at the site of injection is not a side effect of the toxin but rather of the mode of administration, and is reported as preventable if the clinician applies pressure to the injection site; when it occurs, it is reported in specific cases to last 7 11 days . When injecting the masseter muscle of the jaw, loss of muscle function can result in a loss or reduction of power to chew solid foods.
