AP PSYCHOLOGY

Detailed explanation-1: -The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.

Detailed explanation-2: -The nervous system transmits signals between the brain and the rest of the body, including internal organs. In this way, the nervous system’s activity controls the ability to move, breathe, see, think, and more. The basic unit of the nervous system is a nerve cell, or neuron.

Detailed explanation-3: -What is the main purpose of the nervous system? The–nervous system receives information from sense organs and analyzes that information. When a response to information is initiated, the–nervous system carries the response to the rest of the body.

Detailed explanation-4: -Your sympathetic nervous system is the part of your nervous system that carries signals related to your “fight-or-flight” response. That makes it a key part of your response to stressful situations.

Detailed explanation-5: -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. Then the nerves interpret the information and control your response.
