  1. Introduction to the Nervous System

  2. General Functions of the Nervous System • Master Controlling and Communicating System in the body

  3. General Functions of the Nervous System • Master Controlling and Communicating System in the body • 3 Functions:

  4. General Functions of the Nervous System • Master Controlling and Communicating System in the body • 3 Functions: • Monitor changes inside and outside the body (sensory input- gathering info.)

  5. General Functions of the Nervous System • Master Controlling and Communicating System in the body • 3 Functions: • Monitor changes inside and outside the body (sensory input- gathering info.) • Processes information and makes decisions – called integration

  6. General Functions of the Nervous System • Master Controlling and Communicating System in the body • 3 Functions: • Monitor changes inside and outside the body (sensory input- gathering info.) • Processes information and makes decisions – called integration • Motor output (motor=muscle) response by activating glands or muscles

  7. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS)

  8. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) Parts: brain and spinal cord

  9. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) Parts: brain and spinal cord Functions: Body’s control system

  10. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) Parts: brain and spinal cord Functions: Body’s control system Receives sensory input Relays motor impulse via efferent nerves

  11. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) Parts: brain and spinal cord Functions: Body’s control system Receives sensory input Relays motor impulse via efferent nerves Center for higher function- intelligence, memory, emotion

  12. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Parts: nerves outside the CNS

  13. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Parts: nerves outside the CNS • Function: • Sensory- nerves to CNS (afferent). Carries impulses from receptors to CNS.

  14. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Parts: nerves outside the CNS • Function: • Sensory- nerves to CNS (afferent). Carries impulses from receptors to CNS. • Motor (efferent) nerves from CNS to effector. Carries impulses from CNS to effector (muscles or glands).

  15. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Divisions of the motor system • Somatic Nervous System

  16. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Divisions of the motor system • Somatic Nervous System Voluntary- afferent nerves from skin and muscles go to CNS. Efferent nerves from CNS to skeletal muscles.

  17. Divisions of the Nervous System Peripheral Nervous System Central Nervous System (CNS) • Divisions of the motor system • Somatic Nervous System Voluntary- afferent nerves from skin and muscles go to CNS. Efferent nerves from CNS to skeletal muscles. • Autonomic Nervous System Involuntary- afferent nerves are from internal organs to CNS. Efferent nerves from CNS to cardiac or smooth muscles.
