The brain is located in the head. Because it is very delicate, it is protected by the cranium (skull), a very strong bone. It is connected to all body parts by a system of nerves.
The nerves are of three types: - the sensory, relay and motor nerves.
Sensory nerves- carry messages to the brain.
Relay nerves- are involved in interpretation of information
Motor nerves- effects the necessary changes (responses).
“A brain that is not exercised (dull brain) rusts!’’
