The morphology structure of the larynx is studied according to the cartilages, muscles, nerves, blood vessels, and membranes of which it is composed.

The larynx is composed of an external skeleton of cartilage plates that prevents collapse of the structure.

Syllabus - Human Physiology Lecture

The plates are fastened together by membranes and muscle fibres. The plates tend to be replaced by bone cells beginning from about 20 years of age onward. The epiglottisat the upper part of the larynx, is a flaplike projection into the throat. As food is swallowedthe whole larynx structure rises to the epiglottis so that the passageway to the respiratory tract is blocked.

After the food passes into the esophagus food tubethe larynx relaxes and resumes its natural position. The centre portion of the larynx is reduced to slitlike openings in two sites.

Both sites represent large folds in the mucous membrane lining the larynx. The first pair is known as the false vocal cordswhile the second is the true vocal cords glottis. Muscles attached directly and indirectly to the vocal cords permit the opening and closing of the folds.

Speech is normally produced when air expelled from the lungs moves up the trachea and strikes the underside of the vocal cords, setting up vibrations as it passes through them; raw sound emerges from the larynx and passes to the upper cavities, which act as resonating chambers or in some languages, such as Arabic, as shapers of soundand then passes through the mouth for articulation by the tongueteeth, hard and soft palates, and lips.

If the larynx is removed, the esophagus can function as the source for sound, but the control of pitch and volume is lacking.

In other forms of animal life, sounds can be produced by the glottisbut in most, the ability to form words is lacking. Reptiles can produce a hissing sound by rushing air through the glottis, which is at the back of the mouth.

Frogs produce their croaking sounds by passing air back and forth over the vocal folds; a pair of vocal sacs near the mouth serve as resonating chambers. In birds the larynx is a small structure in front of the trachea; it serves only to guard the air passage.
