    Warming Up Questions

    • What are the major differences in the divisions of the nervous system?
    • (Relevant video link provided)

    The Central Nervous System (CNS)

    • The nervous system consists of two major divisions:
      • Central nervous system (CNS)
      • Peripheral nervous system (PNS)
    • Made up of brain and spinal cord
    • Acts as the body's control center, coordinating activities
    • Impulses travel through neurons in the body to reach the brain
    • The CNS is mostly made up of interneurons.
    • Coordinates all bodily activities
    • Relays, processes information, and analyzes responses

    The Brain

    • The brain is sometimes called the control center of the entire body.
    • The cerebrum is the largest part of the brain and carries out thought processes involved with learning, memory, speech, voluntary body movements, and sensory perception.
    • The cerebellum controls balance, posture, and coordination, located at the back of the brain.
    • The medulla oblongata relays signals between the brain and other parts of the body.
    • The pons relays signals between the cerebrum and cerebellum, and helps control breathing.
    • The hypothalamus regulates body temperature, thirst, balance, and partially regulates blood pressure, sleep, aggression, fear, and sexual behavior.

    The Spinal Cord

    • Nerve column that extends from the brain to the lower back
    • Protected by the vertebrae
    • Processes information

    The Peripheral Nervous System (PNS)

    • Consists of sensory and motor neurons that carry information to and from the CNS
    • Neurons in the peripheral nervous system are classified as either part of the somatic nervous system or the autonomic nervous system.

    The Somatic Nervous System

    • Nerves in this system relay information from external sensory receptors to the CNS, controlling voluntary movements.

    The Autonomic Nervous System

    • Carries impulses from the CNS to the heart and other internal organs
    • The body responds involuntarily, not under conscious control.
    • The sympathetic nervous system is most active in times of emergency or stress, when the heart rate and breathing rate increase.
    • The parasympathetic nervous system is most active when the body is relaxed.

    Additional Information

    • Provided lesson activities for different groups (e.g., describing the function of the nervous system, explaining folds and grooves in the cerebrum, discussing the importance of the CNS, position of the cerebrum in relation to the cerebellum, hypothesizing tests to assess brain function).
    • Included a question about classifying the type of nervous system test and hypothesis needed by researchers.
    • Provided quiz questions related to the nervous system, including the function of the hypothalamus, the term that best describes nerves relaying information from external receptors to the CNS, and the characteristics of the sympathetic nervous system.
