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
