Parasympathetic nervous system consists of:
Correct answer: A. craniosacral outflow
- A. craniosacral outflow
- B. lumbocranial outflow
- C. thoracolumbar outflow
- D. caniothoracic outflow
- E. thoracosacral outflow
Explanation
The correct answer is craniosacral outflow because the parasympathetic nervous system primarily arises from the brainstem (cranial) and the sacral region of the spinal cord. This division is responsible for promoting 'rest and digest' activities, contrasting with the sympathetic nervous system's 'fight or flight' responses.Other options are incorrect because lumbocranial outflow inaccurately combines lumbar and cranial areas, while thoracolumbar outflow specifically refers to the sympathetic nervous system. caniothoracic outflow is not a recognized term in this context, and thoracosacral outflow is a misnomer that does not accurately describe any part of the autonomic nervous system.

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.
