The first simulations involved static rigid-beam models, assuming the mandible to be nonflexible and muscles to contract isometrically. |
The halecostomes, of which Amia is an example, have an opercular dilator muscle originating on the mandible which opens the operculum. |
Those muscles below the mandible are anatomically described as being above or below the hyoid bone. |
The quadratomandibularis extends between the palatoquadrate and mandible and may assist in protruding the upper jaw in all elasmobranchs. |
Following the collection, the bees fly near the flower and move the resin ball from the mandible to one of the corbiculae. |
The edentulous anterior portion of the mandible is approximately half as thick as the tooth-bearing region. |
