XX. Autonomic Nervous System 2011 Kimball Learning Outcomes: Be able to: Describe the anatomy of the sympathetic and parasympathetic nervous system 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 Characteristics of ANS Visceral motor neurons Target organs: Cardiac muscle Smooth muscle Glands Adipocytes 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 Two Divisions of ANS Sympathetic “fight/flight” Parasympathetic “rest/digest” Almost every target organ: Smooth muscle Cardiac muscle Glands Receives dual innervation from both divisions Sympathetic Division (“Thoracolumbar” division) Origin: Preganglionic cell bodies spinal cord segments T1-L2 Most preganglionic axons synapse in sympathetic chain ganglia Some synapse “further out” in collateral ganglia ( which surround aorta) A few go straight to adrenal gland Compared to parasympathetic system, sympathetic system has short preganglionic and long postganglionic neurons 1

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
