Detailed explanation-1: -It regulates your body’s systems and allows you to experience your environment. A vast network of nerves sends electrical signals to and from other cells, glands, and muscles all over your body. These nerves receive information from the world around you.
Detailed explanation-2: -Abstract. The central nervous system (CNS) is designed to respond to the environment and is peculiarly vulnerable to many of the influences found in the environment.
Detailed explanation-3: -It controls intelligence, memory, personality, emotion, speech, and ability to feel and move. It is divided into left and right hemispheres, linked by a band of nerve fibres in the centre of the brain called the corpus callosum. Each hemisphere is divided into 4 lobes, or sections, which are all connected.
Detailed explanation-4: -They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
