CENTRAL NERVOUS SYSTEM
Central nervous system acts as a control central of the whole nervous system. It comprises brain and spinal cord.
Brain
Human brain in enclosed in a bony skull called cranium and consist of billions of inter-neurons. It is divided into the followings method.
Midbrain
Midbrain is a small part of the brain which is present below the cerebrum. It receives information from sense organs which is then passed to the appropriate part of the forebrain.
Hindbrain
Hindbrain consist of three parts cerebrum, pons and medulla oblongata. Cerebellum lies under the back part of the cerebrum. It acts as a controller maintaining the body balance and making precise and accurate movement. Pons is an oval structure present beneath midbrain. It controls many function like sleep, swallowing, equilibrium and taste. Medulla oblongata forms the posterior part of the brain where it is connected with the spinal cord. Medulla oblongata control heartbeat, breathing and digestion. Medulla oblongata keeps on working when rest of the brain goes to sleep.
SPINAL CORD
Spinal cord is an extension of medulla oblongata. It runs backwards inside the backbone up to its lower end. It is also made up of inter-neurons. Spinal cord creates a link between brain and different body parts.
