AP PSYCHOLOGY

Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.

Detailed explanation-2: -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-3: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-4: -The central nervous system’s responsibilities include receiving, processing, and responding to sensory information.

Detailed explanation-5: -Through its receptors, the nervous system keeps us in touch with our environment, both external and internal.
