Exempel på hur man kan använda MANDIBULAE i en mening

• On the edge of the braincase, a spur of bone divides the spiracular cleft (a hole which hosted the spiracle or ear canal) from the depressor mandibulae fossa (a pocket for the muscles which open the mouth).
• The mammalian stapedius evolved from a muscle called the depressor mandibulae in other tetrapods, the function of which was to open the jaws (this function was taken over by the digastric muscle in mammals).
• Muscles like the adductor mandibulae externus medialis, which are weak in most crocodilians, became more important as jaw closers and were greatly enlarged.
• Plagiosaurids, which lived during the Triassic, are thought to have been bottom-dwelling piscivores that compensated for their weak depressor mandibulae with powerful adductor muscles that would have rapidly closed the lower jaw.
• It is commonly believed that the Aromobates nocturnus is the sister group of the Dendrobatidae due to its unique characteristics including its larger size, nocturnal and aquatic nature, and the presence of the adductor mandibulae externus superficialis muscle most often found in other Dendrobatids.
• It was named for a notch on its coronoid process which most likely was the insertion point for a chewing muscle, the adductor mandibulae externus.
• The corpus mandibulae is the part of the lower jaw beneath the tooth row, and mekéti (μηκέτι) is Greek for 'no longer'.
• It can be distinguished from other pterosaurs by a long retroarticular process (a process to which the depressor mandibulae muscle attaches, implying that Aymberedactylus had good control over the movement of its jaw bones) and a small fossa, or depression, with a roughened bone texture on the splenial bone.
