The Autonomic Nervous System: Understanding Essentials
1
THE AUTONOMIC NERVOUS SYSTEM:
UNDERSTANDING THE ESSENTIALS
(v2013, long sheet) Lecturer: D.G. Simbulan, Jr., PhD
----------------------------------------------------------------------------------------------------------------------------- -------------------Outline:
I.
Introduction
II.
Comparison between the somatic and autonomic nervous systems
III.
Anatomical and Physiological features of ANS
IV.
Metabolism of Neurotransmitters; Main form of removal from synaptic cleft/ junctional cleft
V.
Receptor Pharmacology and Membrane Potentials
VI.
Interactions of the Autonomic Divisions
VII.
Central Nervous Integration and Control of Autonomic Functions
VIII. SPECIAL FOCUS on the Classic Neurotransmitters; Introduction to the Nonclassic
Neurotransmitters And Co-Transmitters of the ANS

-----------------------------------------------------------------------------------------------------------------------------------I. Introduction
1. What are the two general motor subdivisions of the Peripheral Nervous System (PNS) ?
2 Enumerate briefly the functions of the Autonomic Nervous System (ANS)?
3. What are the classical two divisions of the ANS originating from the central nervous system
(CNS)? Give the role of each of these divisions ? (These will be the main focus of this lecture module.) 4. What is a third division of the ANS which can function independently of the two earlier divisions? Give the role of this third division. (This was part of the module on the GASTROINTESTINAL TRACT).
II. Comparison between the somatic and autonomic nervous systems
A. Regarding effectors innervated:
1. What kind of effectors (tissues/ organs) does the somatic nervous system innervate ?
2. What kind of effectors does the autonomic nervous system innervate ?
B. Efferent pathways:
1. Where is the cell body (soma) of the motor/efferent neurons of the somatic nervous sytem located ?
2. Do motor neurons (of the somatic nervous system) have ganglia ?
3. How
