Which of the following is due to parasympathetic systemA. Dilation of ...
In the parasympathetic nervous system, the key neurotransmitter is acetylcholine. This system is responsible for rest and digest functions, promoting relaxation and conservation of energy. It counteracts the effects of the sympathetic nervous system, which is responsible for the fight or flight response.
The correct answer is option 'C': Inhibits gastric secretion. The parasympathetic system stimulates the release of acetylcholine, which acts on the stomach to increase gastric secretion. This includes the production of stomach acid and the release of digestive enzymes. Therefore, the parasympathetic system does not inhibit gastric secretion but rather stimulates it.
The other options are not due to the parasympathetic system:
- A. Dilation of blood vessels: This is not a function of the parasympathetic system. In fact, the parasympathetic system generally causes blood vessels to constrict, leading to a decrease in blood pressure.
- B. Contraction of urinary blood vessels: The parasympathetic system does not directly control the blood vessels in the urinary system. Instead, it primarily controls the detrusor muscle and sphincters of the bladder, which are involved in the process of urination.
- D. Constrict the eye pupil: This is a function of the parasympathetic system. When the parasympathetic system is activated, it causes the pupils to constrict, allowing less light to enter the eye. This is known as miosis.
Therefore, option 'C' is the correct answer as it accurately represents a function of the parasympathetic system.
