Anatomy and Physiology of the Nervous System Quiz

Sleep and Wakefulness Regulation

• The hypothalamus is responsible for regulating sleep and wakefulness.

Reticular Activating System (RAS)

• The reticular activating system (RAS) is responsible for regulating consciousness, arousal, and sleep-wake transitions.
• The RAS filters out irrelevant sensory information, allowing individuals to focus on important stimuli.

Central Nervous System (CNS)

• The central nervous system (CNS) is composed of the brain and spinal cord.
• The CNS integrates and processes information from sensory receptors, and coordinates body functions.

Blood-Brain Barrier (BBB)

• The blood-brain barrier (BBB) is a semipermeable membrane that separates the circulating blood from the brain.
• The BBB regulates the passage of substances into the brain, protecting it from toxins and maintaining a stable environment.

Motor Control and Balance

• The cerebellum is responsible for coordinating voluntary muscle movements and maintaining balance.
• The cerebellum integrates sensory information from the senses, and adjusts motor responses accordingly.
