For a receiving tennis player, what is the path from the stimulus to the response?

A-The eye receives a stimulus, i.e., the vision of the ball. The eye receptor receives a stimulus and stimulates nerve endings. These produce impulses which travel along with receptor neuron to the spinal cord.

B- In the spinal cord, they are transmitted via synapse to relay neurons. Through another synapse, impulses are transmitted from relay to effector neurons.

C- The effector neuron receives a decision from the brain. Effector neuron moves to the effector i.e., arm.

 The bicep/tricep muscles arrange themselves for the response.
