If you lose nerve connection to skeletal muscle, the muscle cannot function (think about spinal cord injuries). But how exactly does the neuron communicate to the muscle? That's exactly what this video is about -- it's a process called 'excitation -contraction coupling.' Don't you want to know how it works? Of COURSE you do! • #nursingstudent #anatomyandphysiology #physiology #muscularsystem #paramedicschool • Video Chapters: • Intro: 0:00 • Video overview: 0:04 • What is excitation-contraction coupling? 0:33 • Microanatomy: 1:18 • Neuromuscular junction: 1:26 • My simplified cartoon: 1:36 • Muscle cell at rest: 4:06 • Somatic motor neuron fires: 4:13 • Nicotinic receptors open: 4:29 • Muscle cell depolarization: 4:55 • DHP receptor changes shape, opens Ryr channel: 5:14 • Ca++ efflux from SR: 5:34 • A note on calsequestrin: 6:14 • Ca++ initiates muscle contraction: 6:46 • The role of Ca++ in the sliding filament model: 6:52 • Summary: 8:05 • Outro: 8:58 • FREE TEXTBOOK: • OpenStax Anatomy Physiology 2e: https://openstax.org/books/anatomy-an... • This content summarizes OpenStax Anatomy and Physiology 2e, Section 10.2 • Penguin Prof Staff: • Organic chemistry consultant in residence: FabioChem (Fabio Agnelli, Ph.D) • Happiness Coordinator: Flops the Penguin • Content Creator, Producer, Editor and Narrator: The Penguin Prof (Valerie Pennington) • Let's Connect! • https://hihello.me/hi/penguinprof-U55i9g • Want more Penguin Prof? • Subscribe: / thepenguinprof • FB Page: / thepenguinprof • Instagram: / penguinprof • TikTok: / penguinprof • Twitter: / penguinprof • Web: http://www.penguinprof.com/ • LinkedIn: / penguinprof • Videos mentioned: • The Action Potential: • HELP With Action Potentials 🐧 • Equilibrium Potentials and Driving Force: • Equilibrium Potentials and Driving Force • Basic Signal Transduction: • Basic Signal Transduction: Ligands a... • Popular Videos: • Cell Membranes EXPLAINED: • Your CELL MEMBRANES 🐧 • Making Happy: Serotonin, Antidepressants and Psychedelics: • Your HAPPINESS: Serotonin, Antidepre... • Take Great Notes: • Take GREAT Notes -- That Help You LEARN! • Should You Use Your Textbook? • Should You USE Your Textbook?
