What is a reflex action?
A voluntary response to a peripheral nervous stimulation
An involuntary response to a peripheral nervous stimulation
A process that occurs only in the peripheral nervous system
A response that requires conscious effort and thought
Answers (1)
A reflex action is an involuntary response to a peripheral nervous stimulation, which occurs without conscious effort or thought. The reflex pathway comprises at least one afferent neuron and one efferent neuron appropriately arranged in a series. The afferent neuron receives a signal from a sensory organ and transmits the impulse via a dorsal nerve root into the CNS (at the level of the spinal cord). The efferent neuron then carries signals from the CNS to the effector.
Option b is the correct answer.
