Question

Quizplus · Accepted Answer

The flow of information in a reflex arc involves the sensory neuron detecting a stimulus and sending the information to the connector neuron, which then relays the message to the motor neuron. The motor neuron then activates the effector cell, leading to a reflexive response. This flow of information is depicted in option B, where the sensory neuron comes first, followed by the connector neuron and then the motor neuron.
