0 in a person or animal, the lower jaw bone -- żuchwa
1 in insects, one of the two parts of the mouth used for biting and cutting food -- żuwaczka
In each there are two small circular, transparent areas, opposite the mandibles.
The mouth-parts (fig. 2) consist of a labrum, maxillae and ligular area which border the preoral cavity, and the mandibles.
Both the labral and mandibular struts bear condyles for the articulation of the mandibles, which are somewhat bluntly pointed, and are without teeth.
Anterior to the mandibles, on the ventral edge of the clypeus, are two pairs of low, rounded papillae.
Of these, he says the second stage is without mandibles, and is of short duration, lasting about two or three days.
The mandibles were taken from frozen specimens, the heads of which were thawed for 10 min and the skin and underlying fat removed.
Neither the mandibles nor the maxillae bear the scraping and cutting that would be expected with defleshing.
The mandibles were all well articulated with the crania and the atlas vertebrae all still present.
