ANATOMY

Detailed explanation-1: -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.

Detailed explanation-2: -2. Motoneuron output is conduction of signals from the integration center, the CNS, and is carried out by a group of effector cells, the muscle cells or gland cells, which actually carry out body’s responses to external stimuli.

Detailed explanation-3: -The nervous system processes and interprets sensory input and decides what actions should be taken. The nervous system activates effector organs such as muscles and glands to cause a response called motor output.

Detailed explanation-4: -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.
