The articulation of insect wings
 Křečková, Adéla ; Prokop, Jakub (advisor) ; Král, David (referee)
The origin of wings is one of the most important innovation in insect evolution which opened new niches due to unique flight abilities. Movement of the wing is provided by the specific wing base structures consisted of the articular sclerites and the flight muscles. In general there are three main types of basal articulation in insects. Neopteran articulation represents presumably the ancetral type from which the others are derived. These are found in two palaeopteran orders Ephemeroptera and Odonata. Palaeoptera differs from Neoptera by incapability of the wing flexion over the abdomen. This incapability is caused by their specific articulation of the wings to the thorax. Various arrangements of wing sclerites among insect groups have significance in respect of phylogeny and thus represent number of important morphological characters. These are therefore used in higher systematics of extant groups as well as scarcely in their extinct fossil relatives. In the present thesis I introduce the review of literature sources concerning the main types of the wing articulation, their homologies and their significance in respect of higher insect phylogeny.
