The ability to vocalize is well-known in gekkonid lizards but relatively little attention has been paid to the structure of the vocal apparatus. In this study we briefly review the structure of the larynx and associated musculature of the tokay gecko as a baseline for a comparative survey of ...
The larynx is the sound generator of voice production and just like a wind instrument it is dependent on the wind space or air reservoir wave, i.e. from the air pressure which passes through the lungs, bronchi and trachea into the larynx. Above the glottis the vocal tract is the resonatin...

Goblet cell hyperplasia of tracheal and bronchial epithelia, increased numbers of alveolar macrophages, squamous metaplasia, and hyperplasia of the larynx were seen in rats after 2 weeks of exposure to smoke. Except for tracheal goblet cell hyperplasia, within 14 to 42 days of exposure commencing ...
As this portion is the most vibrating part of the vocal cord this could be an explanation for the unsolved phenomenon why the fundamental frequencies are 1:2 between men and women while all dimensions of the larynx are 1.5:1. The vibrating midportion of the vocal cord is connected to the ...
