Autonomic Nervous System Physiology Course

Explore the comprehensive physiology of the autonomic nervous system through this 7.5-hour course that systematically covers both sympathetic and parasympathetic divisions. Begin with embryological development of the nervous system and fundamental distinctions between somatic and autonomic systems, then progress through detailed examination of ganglia structure and function. Master the sympathetic nervous system's fight-or-flight responses, including origin, relay mechanisms, and physiological responses, followed by thorough coverage of the parasympathetic system's rest-and-digest functions. Delve into autonomic control mechanisms involving baroreceptors and juxtaglomerular cells, then examine the critical differences between cholinergic and adrenergic nerve fibers. Study neurotransmitter systems including acetylcholine versus norepinephrine pathways, and distinguish between nicotinic and muscarinic receptor types. Analyze the roles of epinephrine and norepinephrine in autonomic function, and explore alpha versus beta adrenergic receptor classifications. Learn specialized cardiovascular reflexes including baroreceptor and Bainbridge reflexes, understanding their roles in blood pressure regulation and cardiac function. Conclude with comprehensive review sessions that consolidate autonomic nervous system concepts and integrate them with broader physiological principles, providing essential knowledge for medical students and healthcare professionals studying neurophysiology and cardiovascular regulation.
