gular pumping (uncountable)

  1. A method of ventilation used in respiration accomplished by expanding and contracting the entire throat in a rhythmic manner that is externally apparent.
    • 1992, Carl Gans & ‎David Crews, Hormones, Brain, and Behavior, →ISBN, page 468:
      Gular pumping also is increased significantly in response to airborne beef odor as compared to control (distilled water) odor (Weldon et al., 1990).
    • 2005, Stephen J. Divers & ‎Douglas R. Mader, Reptile Medicine and Surgery, →ISBN:
      Amphibians breathe in, in part, through positive pressure gular pumping.
    • 2008, J. G. M. Thewissen & ‎Sirpa Nummela, Sensory Evolution on the Threshold, →ISBN, page 71:
      Also unlike turtles, crocodylians close their nostrils and do not exhibit gular pumping when submerged, so underwater olfaction is unlikely (Bellairs and Shute, 1953; Weldon and Ferguson, 1993; Bellairs, 1971, in Weldon and Ferguson, 1993).
    • 2015, Gordon Grigg & ‎David Kirshner, Biology and Evolution of Crocodylians, →ISBN, page 192:
      The olfactory epithelium is ventilated during normal respiration and, because crocodylians are intermittent breathers (Chapter 7), particularly by gular pumping.
