mandibulated การใช้
- They have sclerotised heads with compound eyes and mandibulate mouthparts.
- Mallophaga have mandibulate mouthparts which are located on the ventral side of their head.
- The 1 cm long specimen is a stem-group mandibulate, not directly related to any living species.
- The mouthparts vary greatly between insects of different orders, but the two main functional groups are mandibulate and haustellate.
- In mandibulate mouthparts, the labium is a quadrupedal structure, although it is formed from two fused secondary maxillae.
- The mouthparts very greatly among insects of different orders but there are two main functional groups : mandibulate and haustellate.
- The Wenlock Series offers a diverse macrofauna that includes mandibulate ( " Aquilonifer " ) and a vermiform mollusc ( " Acaenoplax " ).
- In chelicerates, the leg-bearing segments are fused with the anterior segments to form a prosoma, so that in living arthropods a distinct head only exists in mandibulates.
- An in-depth phylogenetic analysis of Panarthropoda included two bradoriid genera, " Kunyangella " and " Kunmingella ", and recovered them as the most basal stem-mandibulates.
- Mandibulates also differ by having antennae, and also by having three distinct body regions : head, thorax and abdomen . ( The cephalothorax ( or prosoma ) of chelicerates is a fusion of head and thorax .)
- Chelicerate head structures differ considerably from those of mandibulates ( i . e . insects, crustaceans and myriapods ); they possess eyes and a single pair of grasping appendages innervated from the brain, plus a labrum-like structure.
- Early insect herbivores were mandibulate and bit or chewed vegetation; but the evolution of vascular plants lead to the co-evolution of other forms of herbivory, such as sap-sucking, leaf mining, gall forming and nectar-feeding.
- Open reduction with direct skeletal fixation allows the bones to be directly mandibulated through an incision so that the fractured ends meet, then they can be secured together either rigidly ( with screws or plates and screws ) or non-rigidly ( with transosseous wires ).
