MEDICAL PHYSIOLOGY

Detailed explanation-1: -Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis. Through its receptors, the nervous system keeps us in touch with our environment, both external and internal.

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: -The nervous system allows an organism to respond quickly to changes in the internal or external environment. The responses to the stimuli are short lasting.

Detailed explanation-4: -Your sympathetic nervous system is a network of nerves that helps your body activate its “fight-or-flight” response. This system’s activity increases when you’re stressed, in danger or physically active.
