Both of them maintain that the voice is something more or other than an expiratory current of air set into vibration by purely physical agencies.
Sudden shutting off of the expiratory blast and the phonation during paroxysmal cough is almost pathognomonic of a movable tracheal foreign body.
The trueexpiratory blast will, however, always be recognized when the tube is in the trachea.
To the peculiar sound of the sudden subglottic, expiratory or bechic arrest of the foreign body the author has given the name "audible slap;" when felt by the thumb on the trachea he calls it the "palpatory thud.
It may also be present with any foreign body whose size and shape are such as to occlude the lumen of the bronchus during its contracted expiratory phase.
The localized swelling about the irritating foreign body completes the expiratory obstruction.
Expiratory valve-like bronchial obstruction by non-radiopaque foreign body, producing an acute obstructive emphysema.
Obstruction complete during expiration, but allowing the passage of air during the bronchial dilatation incident to inspiration, constituting an expiratory valve-like obstruction.
In other words, the expiratory energy is transformed into energy of motion.
In one the breath is expelled powerfully, the object being to bring a strong expiratorypressure to bear on the larynx.
In this condition the expiratory muscles may be very violently contracted, and still no air will escape; indeed, the greater the strength exerted the tighter is the closure of the glottis.
The power of the expiratory blast is just what it would be if one unit of strength were exerted in an "uncontrolled" expiration.
So long as the expiratory pressure is steadily maintained, this tone may be held, and yet no strain is imposed on the vocal cords.
The sudden air pressure exerted on the interior walls of the larynx by the expiratory contraction causes the ventricles of the larynx to expand by inflation.
Mandl advanced the statement that the laryngeal muscles are too weak to withstand the pressure of a powerful expiratory blast, the theory of the vocal action therein embodied met with immediate acceptance.
In the case of the expiratory pressure of five units of strength being "controlled" by an inspiratory contraction of four units, nine units of strength are exerted, and the same result could be obtained by the exertion of one unit.
In singing, on the contrary, the expiratory pressure is much more powerful, yet the expiration must be much slower.
In this way is regulated the amount of the fleshy mass of the vocal cords exposed to the expiratory blast.
For the sake of simplicity, that portion of the expiratory energy expended in friction against the throat walls, tongue, cheeks, etc.
Considered as a mechanical process, tone-production occurs when the energy exerted by the expiratory muscles, in their contraction, is converted into energy of motion of the vocal cords.
That the glottis-closing muscles are too weak to withstand a powerful expiratory pressure is therefore an entirely erroneous statement.
Owing to the small area of the under surfaces of the vocal cords, the air pressure against them is very small, in comparison with the total pressure exerted on the contents of the thorax by the expiratory contraction.
The double expiratory movement may also be detected by allowing the that the expiratory current is not continuous, but is broken into two jets.
When the air is expelled from the lungs its very force pushes the cartilage and vocal cords out, and consequently noise is not produced in the expiratory act.
Making a number of violent expiratory movements to get rid of the gas, he found himself unable to progress on account of the fall of the shells, and sat motionless with his hands before his face.
He tried to pronounce labials, opening and closing the lips rapidly; but the expiratory movement was too weak, and not a single sound was made.
While he was making this attempt, sharp pressure was exerted upon the lower part of the sternum, to provoke expiratory reinforcement.
His custom was, when learning his lessons at school, to punctuate his recital of them with little soft expiratory noises that may still be distinguished to-day among a host of other tics.
These consisted of clonic rhythmical twitches, each preceded by an inspiration and succeeded by an expiratory ejaculation, repeated fifty or sixty times a minute.
Schapiro has reported a case of expiratory "spasm" due to contraction of the buccinators.
Among various expiratory tics may be enumerated the habit of blowing through one's nose or mouth.
They embody disturbances of various functional acts, and may be subdivided into inspiratory and expiratory tics.
At this stage, too, expiratory laryngeal noises are occasionally superadded.
The characteristicexpiratory sound was produced, and so rapid was the inspiration that the blow-hole seemed to close immediately after the expiratory act.
The pulse grew small and feeble, the respirations shallow and labored, with an expiratory moan.
If this theory is true, it helps us in explaining why the large, mediate, and smaller bronchi are closed during the expiratorystage of the paroxysmal cough of pertussis.
In such an one, but also in the other kind which sets in after the expiratory movement, death may occur suddenly, or the attack may be followed by a convulsion which may terminate fatally like any other eclamptic seizure.
This mobility of cancer-nodules of the liver with the inspiratory and expiratory changes serves to distinguish them from tumors of the abdominal walls.
He found by experiment that in the spasmodic expiratory effort the tongue was thrust forward; in the inspiratory movement, drawn backward.
The cyanosis of the face, projection of the eyes, and congestion of the conjunctivæ are due to the expiratory effort.
Defn: Pertaining to, or employed in, the expiration or emission of air from the lungs; as, the expiratory muscles.
Defn: To clear the throat with an audible sound by forcing an expiratory current of air through the narrow passage between the depressed soft palate and the root of the tongue, thus aiding in the removal of foreign substances.
The black surface represents the expiratory contour, while the inspiratory is indicated by a thin line.
Certain Diptera (Calliphora vomitoria and Eristalis tenax) afford the simplest arrangement of the expiratory muscles.
The arrows show the direction of the expiratory movement.
In most Insects, contrary to what obtains in Mammals, only the expiratorymovement is active; inspiration is passive, and effected by the elasticity of the body-wall.
The position of the terga and sterna after an inspiration, is indicated by the thick line; the dotted line shows their position after an expiration, and the arrow marks the direction of the expiratory movement.
On the other hand, the vertical expiratorycontraction is never absent, and usually marked.
The transverseexpiratory contraction is often slight, and may be imperceptible.
We know that during violent expiratory efforts the pressure of the arterial blood within the vessels of the eye is increased, and that the return of the venous blood is impeded.
To return to our point: why are tears secreted during a screaming-fit or other violent expiratory efforts?
One of the most important points, small as it may at first appear, is that the muscles round the eyes are involuntarily contracted during violent expiratory efforts, in order to protect these delicate organs from the pressure of the blood.
We have seen how important a part they play, together with the orbiculares, in protecting the eyes from being too much gorged with blood during violent expiratory movements.
In both cases we carefully endeavour to avoid great expiratory pressure, the disadvantage of which is well known.
In whispering, the larynx takes scarcely any part in the production of the sounds; the vocal cords remain apart and comparatively slack, and the expiratory blast rushes through without setting them in vibration.
The stammerer has full control of the mechanism of articulation, but not of the expiratory blast.
The abdominal muscles relax during inspiration and the diaphragm relaxes during expiration, thus rendering the forces nearly equal, though the strength is in favor of the expiratory muscles.
Hold the breath two counts, and exhale through the mouth with six short expiratory puffs, drawing the ribs in at the side with each puff.
These centres in the medulla preside over the centres in the spinal cord which are in direct relation to the inspiratory and expiratory muscles.
The force of the expiratory blast of air from below overcomes the forces which approximate the edges of the cords and throws them into vibration.
Small an organ as is the larynx it is through it the energy of the expiratory act is transmitted effectively or the reverse to the all-important resonance chambers.
The vocal bands must be so related in function to theexpiratory mechanism that the outgoing blast of air shall be as effective as possible.
Waste occurs whenever air escapes to any appreciable extent through the glottis chink, as that implies an imperfect adjustment of the vocal bands and the expiratory current.
The mucous membrane, the lungs and the expiratory muscles have sole charge of its transmission.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "expiratory" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: asthmatic; nasal; panting; puffing; pulmonary; sniffy; snoring; snuffy; stertorous; wheezing
