We see the same great law in the construction of the mouths of insects: what can be more different than the immensely long spiral proboscis of a sphinx-moth, the curious folded one of a bee or bug, and the great jaws of a beetle?--yet all these organs, serving for such different purposes, are formed by infinitely numerous modifications of an upper lip, mandibles, and two pairs of maxillae. Analogous laws govern the construction of the mouths and limbs of crustaceans.
So with the mouths of insects, we have only to suppose that their common progenitor had an upper lip, mandibles, and two pair of maxillae, these parts being perhaps very simple in form; and then natural selection will account for the infinite diversity in structure and function of the mouths of insects.
On its first arrival it appeared very thirsty, and with exserted maxillae
drank eagerly of drops of water, this same circumstance has been observed by Strack: may it not be in consequence of the little insect having passed through a dry and rarefied atmosphere?
Following completion of this protocol, protraction force is applied to move the maxillae

The zygomatic implant, originated and developed by Dr PI Branemark, has been used as posterior anchorage for implant-supported prostheses in patients with atrophic maxillae
The maxillary apparatus of each individual was extracted after an anterodorsal incision and mounted on a slide to study the details of both maxillae
and the mandibles under an optical microscope.
