There were no reflex, vasomotor or electrical disorders.
Objectively, there were neurasthenic symptoms of a bodily nature; there was vasomotor excitability.
They react abnormally to the temperature of the surrounding medium; there is undoubtedly a local perturbation of the vasomotor and heat-regulating mechanism.
All these physiological variations in the number of the blood corpuscles, are dependent, according to Cohnstein and Zuntz, on vasomotor influences.
The diastolic pressure is determined by the tone in the arterioles and is under the control of the vasomotor sympathetic system.
The general lack of vasomotor tone in the blood vessels together with some atrophy and flabbiness of the coats probably explains the loud sounds.
The proper distribution of blood to the various organs of the body is regulated by the vasomotor system acting on the small arteries which contain considerable unstriated muscle.
The vasomotor control of these vessels plays an important role in the distribution of the blood.
The gradual return of the pressure picture means that the vasomotor mechanism has acted to keep up the pulse pressure.
Other interesting vasomotorphenomena are frequently connected with arteriosclerosis.
Any agent which causes chronic irritation of the whole vasomotor system produces increase in the peripheral resistance with consequent rise in the diastolic pressure.
Normally there are frequent changes in the blood pressure in the organs, but the vasomotor control of normal elastic vessels is so perfect that no symptoms are noted by the individual.
It is the measure of the tonus of the vasomotor system.
This seems to be dependent on purely mechanical causes, and is not a reflex vasomotor phenomenon.
Low pulse pressure usually means a weak vasomotor control and is only found in failing circulation or in markedly run down states, such as after serious illness or in tuberculosis.
Conversely, paralysis of the vasomotor system produces fall of diastolic pressure which, if long continued, results in death.
It would seem that all the evidence now leads us to believe that the capillaries themselves are contractile and it is even possible that they may be under vasomotor control.
Decreased diastolic pressure goes hand in hand withvasomotor relaxation, as in fevers, etc.
The arrest of respiration tends to render the blood venous, and thus aids in stimulating the vasomotor centers, raising the blood-pressure in the body generally, and especially in the erectile tissues.
It is a mildly inflammatory disorder, somewhat similar to urticaria, and presumably due to vasomotor disturbance; the amount of exudation, which is variable, determines the character of the lesions.
These vasomotor nerves, as they have been called, because they preside over the dilatation and contraction of the walls of the bloodvessels (vasa) of the body, are now known to play an important role in every function.
The vasomotor nerves, however, control much more than heat processes and digestion.
Just as there are those who cannot control the vasomotor nerves of the face, and blush furiously with almost no provocation, so there are brain-blushers in whom the rush of blood interferes with proper intellection.
Ergot and hydrastis and its alkaloids seem to have no effect on the vasomotor center.
Any drug or substance that raises the blood pressure by stimulating the vasomotor center or the arterioles, when constantly repeated, will be a cause of hypertension.
Also, atropin sometimes quiets cardiac pain, but it will not steady the heart, may irritate it, and will increase vasomotor tension, although peripheral nerve irritation may be diminished.
Many times, by improving the action of the heart, and also by the action of the drug on the vasomotor center, the pressure in the peripheral circulation may be increased.
Such good action of alcohol is often seen when the surface of the body is cold from chilling, or the extremities are cold from vasomotor spasm.
Chloroform, of course, depressed the vasomotor center, but ether had no effect on this center, or slightly stimulated it.
Camphor in doses large enough to cause convulsions stimulated the vasomotor center.
Nicotin they found to cause intense stimulation of thevasomotor center.
They found that strychnin in large doses may stimulate the vasomotor center moderately, but usually it did not act on this center unless the patient was asphyxiated; then it acted intensely.
It increases the blood pressure, principally by stimulating the vasomotor center and by increasing the heart strength.
Defn: Causing movement in the walls of vessels; as, the vasomotor mechanisms; the vasomotor nerves, a system of nerves distributed over the muscular coats of the blood vessels.
Defn: An alkaloid extracted from jaborandi (Pilocarpus pennatifolius) as a white amorphous or crystalline substance which has a peculiar effect on thevasomotor system.

The drug lowers arterial tension by depressing the vasomotor centres and the heart itself.
The pallor is of vasomotor origin, determined by faults in the distribution of the blood from vasomotor weakness and not by deficient blood formation.
We have often further evidence of vasomotor weakness.
The same vasomotor instability which shows itself in the tendency to syncopal attacks is apparent in many other ways.
Circulatory and vasomotor disturbance probably also accounts for the dyspeptic pains and vomiting which commonly accompany any emotional excitement, or follow any unusual exertion or fatiguing experience.
