Excerpt: ...palate is seen terminating in the uvula, and on each
side, extending from it, are the pillars of the fauces, a pair of
folds between which the tonsil is seen to lie. Fig . 48. View of
the nose, etc., from behind, showing the parts enumerated above. It
is not hard to understand that any considerable amount of swelling
of the lining mucous membrane might give rise to difficulty in
breathing through the nose, and even compel mouth-breathing. Fig .
49 (Spalteholz). Showing well the scroll (turbinated) bones of the
nose, which break up the space and make it more cavernous. It can
be seen that there is free communication behind, between the mouth
and the nasal cavities, and that if the soft palate and the tongue
approximate, the breath-stream must pass into and through the nose,
giving rise to nasality in utterance. A short description of a part
to which many voice-users remain strangers all their lives will now
be given. These resonance-chambers remain, for many, an apparatus
used daily and absolutely essential, yet never examined.
Fortunately, a few illustrations, which should be followed by an
examination of the student's own resonance-chambers and their
various parts as they may be seen in a mirror, will remove all
difficulty in the understanding of them, and prepare for that
detailed study to be recommended in a subsequent chapter. Passing
from before backward, one meets the lips, the teeth and gums, the
hard palate, which is a continuation of the gums; then, suspended
from the hard palate, behind, is the soft palate, back of which
lies the pharynx (often termed "the throat"), and above it and
constituting its continuation, the naso-pharynx; and lying on the
floor of the mouth there is the tongue. Certain of these parts, as
the teeth, gums, hard palate, nasal bones, etc., constitute fixed
structures, and though they determine in no small measure the shape
of the resonance-chambers, and so to a degree the quality of the
voice, so movable...
