One of the lower or outer jaws of arthropods.
The third paired mouth part and fifth cephalic appendage. In the Janiroidea (Asellota: Isopoda), it consists of a basal segment bearing three setose lobes.
(pl., maxillae) Paired, ventral sclerite of the mouthparts that forms the lateral portion of the labiomaxillary complex. [drawing][photo][drawing
(pl. maxillae) the second pair of feeding appendages in an insect, usually serving to manipulate food into the gut. In hemipterans, the mandibles and maxillae are modified to form thin, piercing stylets.
the paired lateral accessory jaws located immediately posterior of (behind) the mandibles. The maxillae are the second pair of jaws in a mandibulate insect (i.e. insect with biting jaws) and they are structurally more complex than the mandibles. View image
An appendage that has been modified to serve as a lower jaw in chewing.
insects' second pair of jaws. Maxillae also have sensory function.
the part of the skull that holds the all the upper teeth except the incisors.
One of a pair of mouthparts located just behind an insect's mandibles.
The paired appendage of the mouthparts between the mandible and the labium, consisting of the cardo, stipes, lacinia, galea, and maxillary palpus.
Paired bone of skull situated behind premaxilla and anterior to palatine; this bone bears all upper teeth except incisors.
limbs of the head modified as mouthparts; two pairs lie just posterior to the mandibles; sometimes a limb of the first pair is called a maxillule and the second pair a maxilla
one of a pair of two sets of gnathal appendages situated immediately posteroventral to mandibles.
Maxilla and mandible are found as mesodermal masses on either side of the mouth. The semilunar ganglion of nerve V, the trigeminal, branches to the maxilla, the mandible, and has a sensory branch to the eye muscles.
One of a pair of facial bones that form the base for the upper dental arch, floor of the nose and much of the lower border of the orbit and cheek bones.
