Which of the following is not a sympathetic effect?
A. Increased blood pressure
B. Increase storage of glycogen from glucose
C. Increased heart rate
D. Increase the constriction of the blood vessels.

Explanation

Solution

Autonomic nervous systems is classified into sympathetic and parasympathetic systems. The autonomic neural system transmits impulses from the central nervous system to the involuntary organs and smooth muscles of our body.

Step by step answer: The actions of the sympathetic nervous system are called sympathetic effects. They cope with our body to face a stressful condition. At the time of stress conditions, a sympathetic system is activated. Stress conditions are the time at which the body needs a high amount of energy. To fulfill this more and more glycogen is converted to glucose. So, a sympathetic system increases the blood glucose level in our body. It also increases the heart rate which thereby increases the cardiac output. It is done because more blood is needed by the tissues. The vascular tone of the blood vessels increases and it results in increased blood pressure. The urinary bladder is relaxed and the temptation for urination is delayed. The breathing becomes more rapid as the body needs more and more oxygen to produce more energy. Piloerection is also seen as a part of a sympathetic response.
We must note that an increase in the amount of secretion of catecholamines from the adrenal medulla is seen at stress conditions along with sympathetic response. Increased release of these hormones also causes similar effects. Catecholamines are accompanied by the release of hormones like cortisol. But if the stress condition lasts a longer period, it creates several problems for us.
Hence the correct option is B

Note: When the stress condition is reversed, the body needs to come back to the normal stage. It is done with the help of a parasympathetic system. It decreases heart rate, BP decreases, breathing rate, and also increases the conversion of glucose into glycogen.
