Larynx

The human voice is produced by the larynx.

The glottis is part of the larynx.

Frederick III was emperor of Germany for only ninety-nine days. He died of cancer of the larynx from constant smoking. Thus, tobacco influenced German history.

The trachea, or windpipe, is a cylindrical tube extending from the lower part of the larynx to where it divides into the bronchi.

What is the difference between the pharynx and larynx?

What's the difference between the pharynx and larynx?

There is one thing, among abundance of others, in Anatomy, which has always much affected me with Admiration, [...] It is the Situation and Elaſticity of the Epiglottis, a ſoft Cartilaginous Cover to the Larynx, or Orifice of the Wind-pipe; that this Epiglottis ſhould, all a Man's life, be drawn up, for the Benefit of Reſpiration, and fall down and ſhut, whilſt every bit we eat, and every drop we drink, paſſes over it into the Gullet and Stomach; and that we ſhould ſo ſeldom have Occaſion to cough up a crum, or drop, that may accidentaly ſlip into the Larynx; [...]

The larynx is the instrument of the voice, of which the rima glottidis is the immediate organ. [...] The change of the voice from acute to grave at the time of puberty, when the larynx undergoes a remarkable development, as well as its acuteness in females, whose glottis is less by one third than that of man, shew that the size of the aperture has a great influence.

The differences in the voices of man and woman cannot but have been always obſerved; and their larynxes exhibit, on a merely ſuperficial inſpection, a great diſproportion in ſize.

I hope to be understood as not implying that there is no peculiarity of the larynges and tracheæ, except in some genera; for I believe all have the admirable mechanism of the organ of voice differently constructed, with corresponding muscles, and distribution of nerves, producing those various modulations of sound so familiar to us, and destined for the excitement of love, as well as for other purposes.
