Document Summary
Abdomen: in organisms that have undergone tagmosis the trunk often develops into two tagma, one involved in locomotion and one that is not locomotory. The tagma not involved in locomotion is referred to as the abdomen. Accessory glands: in the males the accessory glands makes the casing to store the sperm. Alinotum: the notum is divided into the anterior alinotum and the posterior postnotum. The alinotum is connected to the membranous part of the pleura that lies below, and this allows the alinotum to move up and down relative to the box below. Apodeme: rigid-like ingrowth of the exoskeleton of an arthropod that supports internal organs and provides attachment points for muscles. This is what is called the click mechanism. To be able to get the wing back up, there needs to be a new way to get the nottum back up. When the box is squeezed the nottum will pop back up and change its position.
