Nervous System
Muhtasari
A goat that snatches its hoof off a hot zinc roofing sheet before it even feels the burn, and a bull that arrives at the Kano abattoir with a pounding heart and a silent gut after a rough truck ride from Sokoto, are both being run by the same system: the nervous system. It is the fastest communication network any animal owns, and a stockman who understands it reads an animal's behaviour, health and stress the way a mechanic reads an engine.
In this lesson you will learn the two divisions WAEC expects you to know: the central nervous system, brain and spinal cord, which processes information and fires reflexes, and the autonomic nervous system, whose sympathetic and parasympathetic halves pull the heart, gut and lungs in opposite directions without the animal ever choosing to. You will trace a reflex arc, contrast fight or flight against rest and digest, and see why this physiology decides how a stockman handles, transports and reads the health of every animal in the pen.
