Notum

from Wikipedia, the free encyclopedia

The term notum (from ancient Greek νῶτον nōton , German “back” ) describes the anterior sclerotized (hardened) part of the tergum in insects . The nota of the three segments of the thorax are called pronotum (front chest) , mesonotum (middle chest) and metanotum (rear chest) from front to back .

A tergum (plural terga ) is the dorsal (back) part of a body segment up to the pleura . The terms tergum and notum are often used synonymously.

Each secondary delimited by Notum district is as Tergit referred to, for example neck plate (Proscutum) and tag ( scutellum ). In the case of segments of the abdomen in particular , the term tergite is often used for the entire notum.
