  • Peripheral Nervous System: How Signals Reach Muscles & Glands
    The division of the nervous system that transmits impulses from the CNS to muscles or glands is the peripheral nervous system (PNS), specifically the motor division.

    Here's a breakdown:

    * Central Nervous System (CNS): This is the "control center" of the nervous system, consisting of the brain and spinal cord.

    * Peripheral Nervous System (PNS): This is the network of nerves that connects the CNS to the rest of the body.

    * Motor Division: This division carries signals *away from* the CNS to effectors (muscles and glands). It is further divided into:

    * Somatic Nervous System: Controls voluntary movements of skeletal muscles.

    * Autonomic Nervous System: Controls involuntary actions of smooth muscles, cardiac muscles, and glands.

    In summary: The motor division of the PNS transmits impulses from the CNS to muscles or glands, allowing for both voluntary and involuntary actions in the body.
