    en.wikipedia.org/wiki/Autonomic_nervous_system

    Autonomic nervous system, showing splanchnic nerves in middle, and the vagus nerve as "X" in blue. The heart and organs below in list to right are regarded as viscera. The autonomic nervous system has been classically divided into the sympathetic nervous system and parasympathetic nervous system only (i.e., exclusively motor).

  3. Electrodermal activity - Wikipedia

    en.wikipedia.org/wiki/Electrodermal_activity

    Sweating is controlled by the sympathetic nervous system, [4] and skin conductance is an indication of psychological or physiological arousal. If the sympathetic branch of the autonomic nervous system is highly aroused, then sweat gland activity also increases, which in turn increases skin conductance.

  4. Dysautonomia - Wikipedia

    en.wikipedia.org/wiki/Dysautonomia

    Dysautonomia, autonomic failure, or autonomic dysfunction is a condition in which the autonomic nervous system (ANS) does not work properly. This may affect the functioning of the heart , bladder , intestines , sweat glands , pupils , and blood vessels.

  5. Reflex syncope - Wikipedia

    The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. [2] Diagnosis is based on the symptoms after ruling out other possible causes. [3] Recovery from a reflex syncope episode happens without specific treatment. [2]

  6. Sympathetic nervous system - Wikipedia

    en.wikipedia.org/wiki/Sympathetic_nervous_system

    Sudomotor function refers to the autonomic nervous system control of sweat gland activity in response to various environmental and individual factors. Sweat production is a vital thermoregulatory mechanism used by the body to prevent heat-related illness as the evaporation of sweat is the body’s most effective method of heat reduction and the only cooling method available when the air ...

    One clinical test for the patient that can be performed is the QSART, or the Quantitative Sudomotor Axon Reflex Testing, which stimulates the autonomic nervous system of an individual by stimulating sweat glands through the promotion of axon reflexes. [9]
