(n.) The dorsal plate of the prothorax in insects. See Illust. of Coleoptera.
Example Sentences:
(1) The bursa copulatrix is as long as the dorsal spines of pronotum.
(2) The egg showed sculpturing typical of C.hemipterus, the female parent, and the nymph conformed to the narrow pronotum and abdomen of this species, being significantly different from C.lectularius in the width of the abdomen.
Prothorax
Definition:
(n.) The first or anterior segment of the thorax in insects. See Illusts. of Butterfly and Coleoptera.
Example Sentences:
(1) This orientation centred prey on the median plane and brought it within an attack zone relative to the prothorax.
(2) The device was used to train cockroaches with intact central nervous systems to keep a mesothoracic leg lifted to avoid shock to the prothorax.
(3) Four of these patients had fracture of prothorax ribs, and 10 fracture of lateral thorax ribs.
(4) The absence of Antp+ function during embryogenesis results in the larval mesothorax exhibiting characteristics of the prothorax and an ensuing lethality; the loss of Antp+ function in the development of the adult thorax causes specific portions of the leg, wing and humeral imaginal discs to develop abnormally.
(5) First, tsh is required critically for the identity of the anterior prothorax.
(6) A map of 60 + 1 cells is repeated in each of the three thoracic segments, with an additional median cell developing late at the anterior end of the prothorax.
(7) However, those imaginal discs that arise anteriorly to the prothorax do not appear to be sensitive to this form of gene regulation.
(8) To investigate further these intrinsic properties and also extrinsic factors involved in guiding axon growth and determining synaptic connectivity, pieces of epidermis from the head were transplanted to the posterior head, prothorax, or mesothorax.
(9) It has been shown previously that in Polycomb lethal embryos posterior transformations require the normal function of the BX-C. We show here that anterior transformations of the mesothorax and other segments require the normal function of the Sex combs reduced (Scr) locus, also necessary for the normal development of the prothorax and some head segments.
(10) Decapitating newly emerged Blaberus craniifer females near the prothorax severs connections between the suboesophageal and prothoracic ganglia, thus depriving them of the neuroendocrine cephalic complex (including brain and suboesophageal ganglion) and the anterior end of prothoracic glands (PGs).
