1. The Central Nervous System (CNS) --> composed of the brain and the Spinal Cord

Function: They integrate and control centers

2. Peripheral Nervous System (PNS) --> composed of the cranial nerves and spinal nerves

Function: Communication lines between the CNS and the rest of the body

3. Sensory Division (Afferent) --> composed of Somatic and Visceral Sensory Nerve Fibers

Function: Conducts impulses from receptors to the CNS

4. Motor Division (Efferent) --> composed the Motor Nerve Fibers

Function: Conducts impulses from the CNS to effectors (muscles and glands)

5. Sympathetic Division

Function: Mobilizes body systems during activity (fight or flight)

6. Autonomic Nervous System (ANS) --> composed of Visceral Motor (Involuntary)

Function: Conducts impulses from the CNS to Cardiac Muscles, Smooth Muscles, and Glands

7. Somatic Nervous System ---> composed of Somatic Motor (Voluntary)

Function: Conducts impulses from the CNS to skeletal muscles

8. Parasympathetic Division

Functions: Conserve Energy and promotes "housekeeping" functions during rest
