In humans, one of the functions of sympathetic nervous system is to
Correct answer: C. Reduce digestion
- A. Constrict pupils
- B. Contract the bladder
- C. Reduce digestion
- D. Decrease the heartbeat
Explanation
The sympathetic nervous system is responsible for the body's 'fight or flight' response, which prepares the body to react to stressful situations. One of its functions is to reduce digestion, as energy is redirected towards more immediate needs like muscle activity and increased heart rate. Option C is correct because it accurately describes this function. The other options describe actions that are actually opposite to what the sympathetic nervous system does: it dilates pupils rather than constricts them, relaxes rather than contracts the bladder, and increases rather than decreases heart rate.

About Neurons and Nerve Impulse
Neurons receive and transmit information through dendrites, the cell body and axons. The topic explains resting potential, depolarization, repolarization, refractory periods and saltatory conduction, followed by synaptic transmission through neurotransmitters. An action potential is distinct from the graded potential produced at a receptor.
