The trophi, or mouthparts of a locust, a typical chewing insect: 1 Labrum. 2 Mandibles; 3 Maxillae. 4 Labium. 5 Hypopharynx. Examples of chewing insects include dragonflies, grasshoppers and beetles. Some insects do not have chewing mouthparts as adults but chew solid food in their larval phase.
Maxilla (arthropod mouthpart) In this malacostracan crustacean diagram, the maxillae are labelled maxilla and maxillula. In arthropods, the maxillae (singular maxilla) are paired structures present on the head as mouthparts in members of the clade Mandibulata, used for tasting and manipulating food. Embryologically, the maxillae are derived ...
In general, arthropods have mouthparts for cutting, chewing, piercing, sucking, shredding, siphoning, and filtering. This article outlines the basic elements of four arthropod groups: insects, myriapods, crustaceans and chelicerates. Insects are used as the model, with the novel mouthparts of the other groups introduced in turn.
mouthparts. Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions (called tagmata ...
The subphylum Hexapoda (from Greek for 'six legs') or hexapods comprises the largest clade of arthropods and includes most of the extant arthropod species. It includes the crown group class Insecta (true insects), as well as the much smaller class Entognatha, which includes three groups of wingless arthropods that were once considered insects: Collembola (springtails), Protura (coneheads) and ...
The strong, segmented limbs of arthropods eliminate the need for one of the coelom's main ancestral functions, as a hydrostatic skeleton, which muscles compress in order to change the animal's shape and thus enable it to move. Hence the coelom of the arthropod is reduced to small areas around the reproductive and excretory systems.
In vertebrates, the maxilla (pl.: maxillae / mækˈsɪliː /) [2] is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. [3][4] The two maxillary bones are fused at the intermaxillary suture, forming the anterior ...
Antenna (biology) Large antennae on a longhorn beetle. Antennae (sg.: antenna), sometimes referred to as "feelers", are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
