Reflex action
- Quick and unconscious movement in response to stimuli
- Path followed to complete reflex action is called Reflex arc.
Reflex action involved following steps:
- Receptor or sensory neuron in cutaneous carry impulse towards CNS.
- This impulse is received through posterior horn of spinal cord.
- Now, interneuron sensed impulse and perceives the situation.
- This nerve impulse from interneuron is received by motor neuron through anterior horn.
- Motor impulse is sent to effector organ and response accordingly.
