I understood more during this 32 min video than 6 hours of lecture XD. Thank you for your explanations and visuals!

[missbrainy]

Best video for a brief overview even for mbbs students

🎯 Key Takeaways for quick navigation:

00:00 📚 This video covers autonomic nervous system pharmacology, which is divided into the parasympathetic and sympathetic branches.
02:32 🧠 Understanding that both branches control the same organs but have opposing effects (fight-or-flight vs. rest and digest) is crucial.
04:26 🚦 Autonomic receptors include ionotropic (ion channels) and metabotropic (GPCRs) receptors, which play a significant role in drug action.
06:11 💊 Cholinergic receptors (muscarinic and nicotinic) are associated with the parasympathetic nervous system, while adrenergic receptors (alpha and beta) are linked to the sympathetic nervous system.
10:16 📖 The autonomic nervous system has specific drugs, including agonists and antagonists, that target these receptors to modulate their functions.
19:03 ⚙️ The synthesis of catecholamines (epinephrine and norepinephrine) and their receptors' actions on smooth muscle, heart, and more are discussed.
26:06 🔄 Drugs like sympathomimetics and sympatholytics either mimic or block sympathetic responses, affecting blood pressure, heart rate, and more.
27:13 🧠 Alpha 2 receptor agonists like clonidine and methyl dopa block the sympathetic nervous system in the central nervous system, producing antagonistic effects.
28:32 ⚖️ Epinephrine reversal refers to the conversion of its vasoconstrictor effect into a vasodilatory effect in the presence of an alpha blocker, highlighting drug interactions.
30:04 💔 Vasovagal reflex involves a malfunction where baroreceptors, controlled by both the sympathetic and parasympathetic systems, can lead to conditions like sinus bradycardia, demonstrating how the autonomic nervous system doesn't always function as intended.

Second time watching this video. Much more clear now after going true some practice question from the Mosby’s Book. Likin completing a cicle
Thank you

4:00 I can say with certainty that when under a fight or flight situation (read: presenting in front of classmates) I can experience involuntary constriction of my bladder rather than relaxation

Clonidine used to control Bap for people detoxing from opioids makes more sense why it is a drug of choice. I have worked in detox asan acupuncturist. Your videos are helping me understand so much. Thank you. They are clear and very understandable. I am studying fir my FL RDH prometric pt stimulated computer sections of the boards. I have almost no idea how to study. I graduated in 1981 scored 86 n nationals back then. 95 on clinical sun two states. Things h Ave changed. I am “rusty”. Clinical practice is different from academic understanding. Thank you.

[jorgenrique]

Great way to explain this heavy topic, great job! Helped a lot.

[harshitkumar]

Thank you brother, this video helped a lot. Greetings from India.

[drnasihabiyabani]

It made pharmacology simple for me
Thank you sir 😊😊
