Mouth parts: The mouth lies at the lower part of the head, and the appendages associated with the mouth are called mouth parts. The noninsect lineages of Hexapoda possess entognathous mouthparts, which are concealed inside the head, while ectognathous mouthparts of Insecta articulate externally on the head capsule. The results are compared with previous partial descriptions of the cephalic morphology of this species and other dictyopterans. 96 Which of the following mouth parts of cockroach are unpaired? They are useful to make a wound in the skin of the host. Mandible supports the lower teeth and provides attachment for muscles of mastication (chewing and eating) and facial expression.

The head of Periplaneta is, as in other cockroaches, mostly characterized by plesiomorphies such as the typical orthopteroid mouthparts, the lateral position of the compound eyes, 5-segmented maxillary palps and 3-segmented labial palps, as well as long antennae. The composition of mouthparts in the various hexapod orders is summarized in a table. The other examples include grasshopper, dragonfly and beetle. Only maxillary stylets and mandibular stylets are present in bugs, whereas labrum-epipharynx and hypopharynx along with maxillary stylets and mandibular stylets are also present in mosquitoes.
