Effect of Parasympathetic and Sympathetic Activation on SA Node || Autonomic Control of Heart Rate

📝 Find notes here: https://www.nonstopneuron.com/post/ef... 🌐 Explore our entire animation video library at: https://www.nonstopneuron.com/ Video Summary: Acetylcholine released from parasympathetic nerve endings makes cells of the SA node less excitable and thereby decreases heart rate. Whereas noradrenaline released from sympathetic nerve endings makes the cells of the SA node more excitable and thereby increases heart rate. 🎞 More videos on the Physiology of CVS: • Action Potential In SA Node:    • Action Potential In SA Node || Primary Pac...   • Renin Angiotensin Aldosterone System (RAAS):    • You Will Be Able To ANSWER ALL QUESTIONS o...   • Vasopressin: Synthesis, Release and Effects:    • Vasopressin: Release and Mechanism of acti...   • Baroreceptor Reflex:    • Baroreceptor reflex for Short term regulat...   Simplest Way to Show Circulation of Blood:    • The Simplest way to show the blood circula...   • Fluid Filtration Across Capillary wall:    • Fluid Filtration Across Capillaries || Sta...   • Blood Flow:    • Blood Flow: Laminar vs Turbulent || Reynol...   • Origins of Pressure in the Circulation:    • ONLY 2% of Medical Students Know All the F...   • Physical Properties of Blood Vessels:    • You Know Eerything Said in this Video EXCE...   • Blood Pressure Along The Vascular Circuit:    • DON'T TAKE THIS FOR GRANTED: Blood Pressur...   • Pacemaker:    • Pacemaker Tissues of the Heart: SA Node, A...   • Conductive System of The Heart:    • Conductive System of The Heart || AV Node,...   • Action Potential In Cardiac Muscle:    • Action Potential In Cardiac Muscle || Hear...   ● Follow me at: • Instagram:   / nonstopneuron   • Facebook:   / nonstopneuron   Chapters 00:00 Intro 00:45 Action Potential in SA Node 02:20 Parasympathetic Effect 06:03 Sympathetic Effect 07:51 Summary Dr. Vipul Navadiya DISCLAIMER: This video is for education purposes only.
