What is maxillae in insect?

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.

How does a hypopharynx function in most insects?

The hypopharynx, a tongue-like structure in insects with chewing mouthparts (Fig. 2.2A), is also styletiform in mosquitoes and is used to pierce host tissue. Running the length of the hypopharynx is a channel that delivers saliva to the apical portion of the mouthparts during feeding.

What is the role of hypopharynx Shaalaa?

What is the hypopharynx made of?

The hypopharynx comprises the piriform sinuses, the lateral and posterior pharyngeal walls, and the posterior surfaces of the larynx. These structures surround the larynx posteriorly and laterally. Tumors in this region can be difficult to detect because of the recesses and spaces surrounding the larynx.
