11/14/2011 1 Autonomic Nervous System Learning Outcomes: Be able to: • Describe the anatomy of the sympathetic and parasympathetic nervous system ild i i i f l ii l i d f including origin of preganglionic neurons, ganglia, and target organs for postganglionic neurons • Describe innervation and function of the adrenal medulla • Compare and contrast the autonomic and somatic motor divisions • Describe transmitters and receptors for the ANS • List parasympathetic effects • List sympathetic effects • Describe the fight / flight response • Compare and contrast the parasympathetic and sympathetic nervous systems 16-1 Characteristics of ANS Visceral motor neuron • Visceral motor neurons • Target organs: – Cardiac muscle – Smooth muscle – Glands 16-2

11/14/2011 2 Compare somatic / visceral motor neurons: • In ANS, not ONE but rather TWO motor neurons, which synapse in outlying ganglion – Preganglionic neuron originates in CNS – Postganglionic neuron originates in ganglion 16-3 Compare somatic / visceral motor neurons: 16-4

11/14/2011 3 Two Divisions of ANS • Sympathetic “fight/flight” fight/flight • Parasympathetic “rest/digest” • Almost every target organ: • Smooth muscle 16-5 • Cardiac muscle • Glands Receives dual innervation from both divisions Sympathetic Division • Origin: Preganglionic cell bodies spinal cord segments T1-L2 •M o s t preganglionic axons synapse in sympathetic chain ganglia • Some synapse “further out” in collateral ganglia A few go straight POST- 16-6
