5. ORGANIZATION OF THE AUTONOMIC NERVOUS SYSTEM SYMPATHETIC GANGLIA TARGET ORGANS BRAIN SPINAL CORD PARASYMPATHETIC GANGLIA

6. TWO NEURON CHAINS SPINE EFFECTOR ORGAN PRESYNAPTIC NEURON POSTSYNAPTIC NEURON

7. SYMPATHETIC SPINE EFFECTOR ORGAN SYMPATHETIC GANGLIA (NEAR SPINE)

8. PARASYMPATHETIC SPINE EFFECTOR ORGAN PARASYMPATHETIC GANGLIA (NEAR EFFECTOR ORGAN)

9. AUTONOMIC CONTROL IS IN BRAIN STEM HYPOTHALAMUS PITUITARY PONS MEDULLA

10. PARASYMPATHETIC GANGLION NEAR EFFECTOR ORGAN LONG PREGANGLIONIC NEURONS SHORT POSTGANGLIONIC NEURONS “COUCH POTATO” POSTGANGLIONIC NEURONS ARE CHOLINERGIC CRANIAL AND SPINAL NERVES

11. SYMPATHETIC GANGLION NEAR SPINE SHORT PREGANGLIONIC NEURONS LONG POSTGANGLIONIC NEURONS FLIGHT OR FIGHT POSTGANGLIONIC NEURONS ARE ADRENERGIC THORACIC AND LUMBAR NERVES

12. EFFECTS OF ANS

13. DUAL INNERVATION OF MOST VISCERAL ORGANS MOST INNERVATED BY BOTH SYSTEMS EFFECTS ARE OPPOSITE IN MOST CASES TONIC ACTIVITY DOMINANCE

14. EFFECTS OF POSTSYNAPTIC NEUROTRANSMITTERS EPINEPHRINE:FLIGHT OR FIGHT REACTION (SYMPATHETIC) ACETYL CHOLINE: “COUCH POTATO” RESPONSE (PARASYMPATHETIC)

15. FACTORS AFFECTING THE CONCENTRATION OF NE IN THE JUNCTIONAL CLEFT NEURONAL UPTAKE DIFFUSION INTO CAPILARIES UPTAKE INTO EFFECTOR CELLS

16. ENTERIC SYSTEM GI TRACT HAS AN INTRINSIC NERVOUS SYSTEM MYENTERIC AND SUBMUCOSAL PLEXUS MORE NEURONS THAN IN SPINAL CORD

17. THE DIGESTIVE TRACT Lumen Mucosa Submucosal Plexus Circular Muscle Myenteric Plexus Logitudinal Muscle Extrinsic Nerves

18. CONTROL OF DIGESTIVE SYSTEM External Influences Local Influences Receptors in Digestive Tract Intrinsic Nerve Plexuses Extrinsic Autonomic Nerves GI Hormones Smooth muscle Exocrine Gland Cells Endocrine Gland Cells
