2.3.3 The Brain

• The brain is the key component of the nervous system.


  True
• The brainstem regulates basic life functions such as breathing and heart rate.


  True
• Which brain region is responsible for motor learning?

  Cerebellum
• The brain maintains the body's internal balance through a process called homeostasis.

  True
• The brain is composed of three main structures: the cerebrum, cerebellum, and brainstem.


  True
• The brain function of cognition involves processing information, problem-solving, and memory
• What is the largest part of the brain?

  Cerebrum
• What is the role of the brain in the nervous system?

  Controls bodily functions
• The brain allows us to perceive, process, and respond to the world around us.


  True
• The brain controls and coordinates all bodily functions and behaviors
• The cerebellum is located at the back of the brain, below the cerebrum
• The brainstem transmits information between the cerebrum, cerebellum, and spinal cord.


  True
• Imbalances in neurotransmitter levels can contribute to neurological disorders.


  True
• Match the brain function with its description:

  Perception ↔️ Interpreting sensory information

  Motor Control ↔️ Coordinating voluntary movements

  Homeostasis ↔️ Maintaining internal balance
• The cerebellum is responsible for movement coordination and maintaining balance
• Match the brain structure with its key function:

  Cerebrum ↔️ Motor control

  Cerebellum ↔️ Movement coordination

  Brainstem ↔️ Basic life functions
• The brain is responsible for coordinating and controlling voluntary and involuntary movements
• Match the brain function with its description:

  Cognition ↔️ Processing information, problem-solving, and memory

  Perception ↔️ Interpreting sensory information

  Motor Control ↔️ Coordinating voluntary movements

  Homeostasis ↔️ Maintaining internal balance
• What basic life functions does the brainstem regulate?

  Breathing, heart rate, sleep
• Neurotransmitters are chemical messengers in the brain that facilitate communication between neurons
• What is the brain called in the nervous system?

  Central organ
• Order the three main structures of the brain from largest to smallest:

  1️⃣ Cerebrum

  2️⃣ Cerebellum

  3️⃣ Brainstem
• What do the three main brain structures work together to enable?

  Diverse brain functions
• The brain regulates mood, emotional responses, and overall behavior
• What is the central organ of the nervous system?

  The brain
• What is the largest part of the brain called?

  The cerebrum
• What role does the cerebellum play in behavior?

  Maintains balance and posture
• Which neurotransmitter is involved in the stress response and arousal?

  Norepinephrine
• Match the brain region with its key function:

  Cerebrum ↔️ Cognition, perception, motor control

  Cerebellum ↔️ Movement coordination, motor learning

  Brainstem ↔️ Basic life functions, relay station
• Match the neurotransmitter with its primary function:

  Dopamine ↔️ Reward, motivation, movement control

  Serotonin ↔️ Mood, sleep, appetite regulation

  GABA ↔️ Inhibitory neurotransmitter, reduces excitability

  Acetylcholine ↔️ Memory, learning, muscle function
