Epidemic Sound

In this video, I'll explain in simple language how a neuron communicates with a skeletal muscle cell - specifically, the relationship of the speed of the transmission and the muscle cell response. The connection between the neuron and the muscle cell is called a neuromuscular junction, and the graphical relationship between timing of stimulation and resulting muscle tension is called a myogram. Don't worry - I'll break it all down, and Flops is here to help! #anatomyandphysiology #emtstudent #paramedicstudent #nursingstudent #cell #biology #biologystudents This video supports selected content in: OpenStax Anatomy and Physiology 2e Section 10.4 Video Chapters: Intro 0:00 Setting the stage / quiz yourself: 0:06 Neuromuscular junction / quiz yourself: 0:33 What is a myogram? 1:17 What is a twitch? 1:38 What is summation? 3:13 Visual analogy: 3:50 What is tetanus? 4:07 Wait, what about the other tetanus? 5:02 Summary: 5:30 Want more muscle? 6:08 Outro: 6:14 Videos mentioned: Your Muscle Tissue: https://youtu.be/graN5czl1zA Membrane Transport Made EASY: https://youtu.be/aKrZOLm8Who Control Your Muscles (Excitation - Contraction Coupling): http://youtu.be/eLhxnGMBovQ 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?
