The horse’s nervous system
objectives Label a diagram of the nervous system of the horse. List the two most important parts of the nervous system of the horse. Describe the autonomous and central nervous system. List the main parts of the brain. Compare the nervous system to a telecommunications system. List the two types of nerve fibers.
Nervous system supplies information – both ways Electro-chemical conduction
Autonomic nervous system Involuntary, controlled by the brain stem: Respiratory Digestive Eyes Heart Blood vessels Glandular production
Central nervous system Primarily voluntary or conscious actions (skeletal muscle action)

Major parts Two most important: Brain Spinal cord By size – the horse is considered to be in the mid-range of intelligence.
The Brain Three parts: Brain stem, mostly controls the autonomous nervous system Cerebrum, functions of memory, intelligence and emotional response Cerebellum, muscular coordination, balance and equilibrium.
How they work Impulse received – sent along nerve to brain – back to receptor Action takes place Ganglia – collect and transmit impulses that do not need to go to the brain Heat, pain, etc Switched to motor actions - reflex
