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.

  • (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.
