The ears of a rabbit play an important part in helping the animal to keep its body temperature constant. After a period of exercise, the insides of a rabbit’s ears become redder in colour as the blood flow to the skin surface increases. Explain how the different components of nervous communication are involved in the process leading to the response shown by the rabbit’s ears.
