Question

What is in the correct order for the general reflex arc?

Answer 1

Stimulus, sensory neuron, intermediary neuron, motor neuron and defector organ is the correct order of general reflex arc.

Explanation:

Reflex arc starts with a stimulus. The stimulus must be sufficiently strong to initiate impulse in sensory neuron.
Sensory neuron carries the impulse to intermediary neuron.
Intermediary neuron carries the impulse to appropriate motor neuron.
Motor neuron send the impulse to either muscle or gland.
Example of general reflex arc is pricking the needle to a finger. Ultimate action is withdrawal of hand.
