Epipleural: the deflexed or inflexed portions of the elytra, immediately beneath the edge: the inflexed portions of the pronotum are sometimes called prothoracic epipleura: as generally used, the term is incorrectly applied to the entire bent under margin of the elytra. ❋ John. B. Smith (N/A)
Insect molting is controlled by a hormone produced by a gland THE HUMAN BRAIN located in the forward portion of the thorax and therefore called the prothoracic gland. ❋ Asimov, Isaac (1963)
Wings were curved backwards, articulated, and probably used for underwater rowing; prothoracic winglets were fused with protergum. ❋ Unknown (2009)
Osmaterium - ia: fleshy, tubular, eversible processes producing a penetrating odor, capable of being projected through a slit in the prothoracic segment of certain Papilionid caterpillars, and from openings elsewhere in the bodies of other forms. ❋ John. B. Smith (N/A)
Maggot of House-fly (_Musca domestica_), _a_, side-view, magnified 5 times; _b_, prothoracic spiracle; _c_, feeler; ❋ Unknown (1902)
The prothoracic ring, or segment just behind the head, is transversely oblong, being twice as broad as long; there is a pale dorsal corneous transversely oblong shield, being about two-thirds as long as wide, and nearly as long as the four succeeding segments; this plate is smooth, except on the posterior half, which is rough, with the front edge irregular and not extending far down the sides. ❋ Unknown (1872)
The segments are inclined to be of unequal size, the prothoracic ring sometimes becoming almost obsolete, and some of the abdominal rings are much smaller than others; while in Lipura and Anura, the lowest forms of the group, the segments are all much alike in size. ❋ Unknown (1872)
The head is one-half as wide as the prothoracic ring, being rather large. ❋ Unknown (1872)
The prothoracic segment is broader and flatter, and the rough portion of the dorsal plates is larger and less tranversely ovate. ❋ Unknown (1872)
Other Mantidae, of the genus Gongylus, have the anterior part of the thorax dilated and coloured either white, pink, or purple; and they so closely resemble flowers that, according to Mr. Wood-Mason, one of them, having a bright violet-blue prothoracic shield, was found in Pegu by a botanist, and was for a moment mistaken by him for a flower. ❋ Alfred Russel Wallace (1868)
When muscle 51 contracts, the cervical apodemes are permitted to move inwards into the prothoracic cavity because the flexible nature of the propectal plates allows outward deformation of the propectuses. ❋ Richard P. Berry Et Al. (2010)
The second of the prothoracic nerves, IN2, runs to the floor of the propectus, where it presumably innervates a similar battery of mechanoreceptors registering movement between the propectuses and the basisternum. ❋ Richard P. Berry Et Al. (2010)
When corpora cardiaca releases brain hormone, it diffuses to the prothoracic gland. ❋ Unknown (2009)
Then, the prothoracic gland is stimulated and releases ecdysone. ❋ Unknown (2009)
Microarrays developed from the combined libraries were then used to contrast the transcriptome of developing primordia of head horns, prothoracic horns, and legs. ❋ Unknown (2009)
Furthermore, we find that horns developing from the head and prothorax differ in their transcription profiles to a degree that suggests that head and prothoracic horns are not serial homologs, but instead may have evolved independently from each other. ❋ Unknown (2009)
