What is the nervous system?
What is the nervous system?
The nervous system is the body's communication network, responsible for everything from thought to movement.
What is sensory input?
What is sensory input?
Sensory receptors gather information about changes happening inside and outside the body, like seeing a red light while driving.
What is integration?
What is integration?
The nervous system processes and interprets sensory information, deciding how to respond, like recognizing a red light means 'stop'.

Study Notes
Nervous System Overview
- The nervous system is the body's control and communication center, managing thoughts, actions, and emotions.
- It uses rapid electrical impulses for communication with body cells, triggering immediate responses.
- It works alongside the endocrine system to maintain homeostasis.
- The endocrine system regulates through hormones released into the bloodstream, acting more slowly than the nervous system.
Nervous System Functions
- Sensory input: The nervous system monitors internal and external changes (stimuli) in the body, gathering information.
- Integration: The nervous system processes and interprets the sensory input, deciding on a response.
- Motor output: The nervous system activates muscles or glands (effectors) to create a response (effect).
Example of Nervous System Function
- Driving scenario: Seeing a red light (sensory input) triggers the nervous system to process the meaning ("stop") and generate a response (applying the brake).

Description
This quiz covers the essential functions and components of the nervous system, including its role as the body's control and communication center. You will explore how it processes sensory inputs, integrates information, and triggers motor outputs. Compare its rapid responses with the slower actions of the endocrine system.
