anzhelika [568]

The number of heartbeats per minute is known as the heart rate, while the volume of blood that is pumped by the ventricles with each heartbeat is the stroke volume.

A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Typically, a lower heart rate at rest indicates more efficient heart function and sounder cardiovascular fitness.

Leto [7]

Answer: What is unique about Jahir's case of conversion disorder is that this is <u>a psychological condition.</u>

Explanation:

It is a mental condition in which a person has blindness, paralysis or other symptoms of the nervous system (neurological) that cannot be explained by a medical evaluation. Conversion disorder symptoms may occur due to <em>psychological conflict.</em> Symptoms usually begin suddenly after a <em>stressful experience.</em>

People suffering from conversion disorder are not inventing the symptoms in order to obtain accommodation, for example<em> (simulating).</em> They either do not intentionally injure themselves or lie about their symptoms just to become a patient (factitious disorder). Some health care providers falsely believe that this disorder is not a real condition and can tell people that the whole problem is in their head. However, this condition is real. It causes anguish and cannot be controlled at will.

Psychotherapy and stress management training can help reduce symptoms. The affected part of the body or physical function may need physical therapy or occupational therapy until the symptoms disappear.

In response to a threat, we perspire, breathe more quickly, get goose bumps, and feel nauseated. these responses are controlled
topjm [15]

The sympathetic nervous system controls the response to a threat. We perspire, breathe more quickly and get goosebumps and feel nauseated. The correct answer is c. sympathetic nervous system.

The autonomic nervous system responds to information about the body and the environment by either stimulating or inhibiting bodily functions, typically through the sympathetic or parasympathetic nervous systems.There are two primary divisions of the autonomic nerve system-

  • Sympathetic
  • Parasympathetic

The sympathetic nervous system controls the "fight-or-flight" reaction, which is activated by danger or stress and can lead to a number of physiological changes. Most blood vessels, including many in the epidermis, digestive tract, and kidneys, constrict when the sympathetic nervous system is stimulated. This happens due to norepinephrine, released by post-ganglionic sympathetic neurons, activating alpha-1 adrenergic receptors. Sympathetic nervous system may impact these organs while under threat or stress:eyes, heart, lungs, digestive tract, liver, and genitalia.
