ABSTRACT
The nervous system is a complex and highly organised system of electrically active neurones or nerve cells that send and receive signals as electrical impulses. Stimuli from the environment and from the body itself are received and coordinated via sensory receptors, and commands are conveyed to glands (see The Endocrine/Hormonal System) and muscles so that the horse can sense and respond, often in a split second, to internal and external stimuli from light reflections and sound waves, to a rider’s aids, to a potential predator approaching or to a kick from another horse.
