Question

Outline and discuss the 5 steps of the autonomic reflex arc.

Answer 1

Ans. The 5 steps of autonomic reflex arc are outlined below :-

1) Receptor receival: The receptor senses the specific type of internal or external change.

2) Function of sensory neuron: The sensory neuron transmits nerve impulse from receptor into brain or spinal cord.

3) Interneuron transmission: The interneuron conducts nerve impulse from sensory neuron to motor neuron.

4) Motor neuron: The motor neuron transmits impulse from brain or spinal cord to the effector organ.

5) Effector: An eefector is an organ or gland which responds to such impulse due to the stimulation by the motor neuron and produces a reflex or a behavioural reaction.
