The nerve pathway involved in a reflex action including at its simplest a sensory nerve and a motor nerve with a synapse between
Answer:
A reflex arc can be defined as the normal pathway of nerve flow that has the ability to control reflex actions.
Explanation:
The mechanism of nerve flow in vertebrates is a bit complex where the sensor neurons go through synapse leading to the spinal cord.
This is the control source of all actions and motor neurons get activated so as to enable activities. There is no form of late action or late response in anyway.
A reflex arc has five components i.e. receptor, sensory neuron, inter-neuron, motor neuron and effect-or.
When a tennis player plays and hits a ball, he is also subjected to this kind of reflex arc which control his subsequent actions. At this time the skin receptor will get a stimuli to send messages to relay neuron and the motor neuron will send electrical messages to the effector due to which the player will move his hand.
