4. 13 October 2010 Autonomic Nervous System
Anatomy of Sympathetic & Parasympathetic
Locations of cell bodies, routes and lengths of axons
Neurotransmitters
NT receptors, agonists, and antagonists
Single and dual innervation of targets
Sensory Physiology (Chapter 7)
Transduction
Coding for sensory modality, intensity, duration, and location

5. S 1
Figure 6.43
Locations of neuronal cell bodies, ganglia, pharmacology of the neuromuscular junction (NMJ) at skeletal muscle (nAChR)
Diagram of NMJ compared to synaptic varicosities characteristic of autonomic postganglionic axons.
Locations and proximities of target cells and distributions of receptors on target cells.
Somatic = excitatory only at NMJ (ex. Reduced muscle tone)
Autonomic= exitatory or inhibitory depending on NTs and their receptors.

6. S 2
Some single innervation (spleen, kidney, adrenal medulla)
Figure 6.44
Parasympathetic (cranio-sacral) division)
Some Dual innervation with antogonistic effects
Sympathetic (thoraco-lumbar) division

7. S 3
Figure 6.45
Explanation of why activation of the sympathetic division has widespread effects.

8. S 4
Figure 6.46
Antagonist = Curare
Antagonist = Atropine
Adrenal medulla is modified sympathetic ganglion that secretes mainly EPI
