Questions and Answers
What are the five functions of the nervous system?
- Receiving Sensory Input 2. Integrating Information 3. Controlling Muscle and Glands 4. Maintaining Homeostasis 5. Establishing and Maintaining Mental Activity
Define external stimuli and provide examples of it.
External stimuli refers to things that an organism perceives in its external environment. Examples include touch and pain, vision, smell, taste, and sound.
What is the role of the nervous system in maintaining homeostasis?
The nervous system plays a role in maintaining homeostasis by regulating and coordinating the body's internal environment to keep it stable and balanced.

Study Notes
Functions of the Nervous System
- Sensory Input: Collects information from sensory receptors about internal and external changes.
- Integration: Processes and interprets sensory input to determine appropriate responses.
- Motor Output: Activates effector organs (muscles and glands) to produce responses.
- Homeostasis Regulation: Helps maintain stable internal conditions through feedback mechanisms.
- Mental Activity: Enables cognitive functions such as thought, memory, and learning.
External Stimuli
- Definition: External stimuli are environmental factors that can provoke a response from an organism.
-
Examples:
- Light
- Sound
- Temperature changes
- Smells
- Taste sensations
Nervous System and Homeostasis
- Monitors the body’s internal environment and external factors to maintain equilibrium.
- Adjusts physiological processes (e.g., heart rate, breathing) to respond to changes.
- Coordinates responses to keep body systems functioning effectively under varying conditions.
Nervous System and Mental Activity
- Facilitates cognitive functions through the processing of information via neurons.
- Engages various brain regions responsible for memory, decision-making, and problem-solving.
- Modulates emotional responses and social behaviors through neural pathways and neurotransmitters.
