Question

After sympathetic stimulation, which type of activities are not present in a human being?
A. Tachycardia
B. Bronchodilation
C. Micturition
D. Semen ejaculation

Answer 1

Hint:- Sympathetic systema nervous stimulation causes vasoconstriction of most blood vessels, including many of these within the skin, the alimentary canal, and therefore the kidneys. This occurs as a result of activation of alpha-1 adrenergic receptors by norepinephrine released by postganglionic sympathetic neurons.

Complete step-by-step solution:-
Tachycardia is the medical term for a heart rate over 100 beats per minute. There are many cardiac rhythm disorders (arrhythmias) which will cause tachycardia. Sometimes, it's normal for you to possess a quick heartbeat. For instance, it's normal for your pulse to rise during exercise or as a response to worry , trauma or illness. But in tachycardia, the guts beat faster than normal thanks to conditions unrelated to normal physiological stress. Bronchodilators are a kind of medication that makes breathing easier by relaxing the muscles within the lungs and widening the airways (bronchi). Micturition (urination) is the process of urine excretion from the urinary bladder. Most of the time, the bladder (detrusor muscle) is employed to store urine. As it fills, the rugae distend and a constant pressure in the bladder (intravesical pressure) is maintained. This is known as the stress-relaxation phenomenon. Semen, also referred to as semen, is an organic fluid created to contain spermatozoa. The method that leads to the discharge of semen is named ejaculation. Urinary storage may be a function of the sympathetic system nervous , whereas micturition may be a function of the parasympathetic system nervous .
Therefore, Micturition is the right answer i.e. option C

Note:-
The sympathetic system nervous can accelerate pulse , widen bronchial passages, decrease motility of the massive intestine, constrict blood vessels, increase peristalsis within the 0esophagus, cause pupillary dilation, piloerection (goosebumps) and perspiration (sweating), and raise blood pressure.
