HOLES IN THE HEAD
Closets in Human Uranium Must
Be Kept Ventilated.

Air to Insure Health.

Our heads are full of holes that must
be ventilated If We are to remain in
good health. Most people think the air
they inhale goes only to their lungs
and that its one use is 20 purify their
blood The air has another and just
as important function the aeratiou
Of the hidden cupboards and closets
of the head
The nose is sort Of radiator
formed of twisted tubes. in which the
inhaled air is warmed and moistened
When YOU exhale vigorously the air is
forced up into the recess back of the
nose This is called the naso-pharynX
From this many tubes open upward
and backward. each leading 10 one OF
more of the closets in the head.
The best known OF these is the Eus
tachan tube which runs from the
back Of the pharynX to the middle ca.
The middle ear is behind the drum. In
it are situated the little bones that
connect the drum with the nervous APP
paratus of the inner ear. In the rear
walls Of the middle ear 3 large IT
regular opening leading 10 the mas
told antrum. large cavity in the up
per part Of the mastoid bone, behind
the ear This communicates again
with a net work of irregular cavities
that make sponge-like structure OF
the interior of the mastoid process
Air passes through the Eustachlan
tubes into the middle ear and on into
the hollows of the mastoid bone. In
lection also takes the same route. and
this is how nasal catarrh may cause
a serious attack of mastoidIus iha'
can be cured only by terrible anI
often fatal operation that begins witt
chopping open the mastoid bone viii
a chisel and mallet
Over the eyebrows, toward the mid
b die and in the lower part Of tn
frontal bone are the frontal sinuses
irregular cavities which are cOnnecte'
with the middle of the nose by a tub
called the infundibulum.
Behind these again are the cells q
the ethmoid bone, called the anterlo
! and posterior ethmoidal sinuses. Thes
" open also into the nose by two dlheI
D ent tubes The anterior slnuses ope
also into another cavity called the al
I trum of Highmore.
J. The antrum is situated in the cheel
: Immediately over the bicuspid and mi
l. lar teeth Its size varies in difterer
individuals and it is not always tn
} same size on each side of the rae
; 1t opens directly into the pharynX. II
! floor is the alveolar process or I'd
. INNER teeth and its roof is the floor
d the eye cavity.
s Farther back in the head than an
5. of these except the mastoid are III
@ sphenoidal sinuses. They also ope
?. into the pharynx by two round hole
e and they sometimes communlca'
q with the posterior ethmoid cells
u sinuses.
2, MANY of these sinuses communica
with the posterior ethmoid cells or 81
s uses.
er Most of these sinuses communlca
Pr with labyrinths or smaller holes
y the bones about them. Many OF the
OV do not exist at UiIth anu ONi| 40
"a to develop about the seventh yea
growing larger until the age OF abo
III twenty.
IN Vigorous exhalation drives the
m that has been warmed and moisten
ne I'm the lungs into all of these hldd
n cavities in the head. They are the
IS tn contain air. and this air must
become stagnated. II the head
a stopped up by catarrh some OF the
" are sure to become involved. The
w suit is headache. earache and son
ri times insanity.
n Therefore, in breathing 1t is as l
sr. portant to blow air forcibly up IL
i'll the upper pharynx as it is to draw
es down into the lungs.
