2-Minute Neuroscience: Neuromuscular Junction

February 5, 2016


In this video I discuss the neuromuscular junction. The term neuromuscular junction refers to a synapse between a motor neuron and muscle fiber; activity here is essential for muscle contraction and movement. At the neuromuscular junction, the synaptic boutons of a motor neuron are situated over a specialized region of muscle called the end plate. The synaptic boutons release acetycholine, which travels across the synaptic cleft and activates acetylcholine receptors on the muscle fiber. This causes excitation of the muscle cell, leading to muscle contraction. Excess acetylcoholine is removed from the synaptic cleft by the enzyme acetylcholinesterase.

YOUR BRAIN, EXPLAINED

Sleep. Memory. Pleasure. Fear. Language. We experience these things every day, but how do our brains create them? Your Brain, Explained is a personal tour around your gray matter. Building on neuroscientist Marc Dingman’s popular YouTube series, 2-Minute Neuroscience, this is a friendly, engaging introduction to the human brain and its quirks using real-life examples and Dingman’s own, hand-drawn illustrations.

  • Dingman weaves classic studies with modern research into easily digestible sections, to provide an excellent primer on the rapidly advancing field of neuroscience. - Moheb Costandi, author, Neuroplasticity and 50 Human Brain Ideas You Really Need to Know

  • ...a highly readable and accessible introduction to the operation of the brain and current issues in neuroscience... a wonderful introduction to the field. - Frank Amthor, PhD, Professor of Psychology, The University of Alabama at Birmingham, author, Neuroscience for Dummies

  • Reading like a collection of detective stories, Your Brain, Explained combines classic cases in the history of neurology with findings stemming from the latest techniques used to probe the brain’s secrets. - Stanley Finger, PhD, Professor Emeritus of Psychological & Brain Sciences, Washington University (St. Louis), author, Origins of Neuroscience

  • An informative, accessible and engaging book for anyone who has even the slightest interest in how the brain works, but doesn’t know where to begin. - Dean Burnett, PhD, author, Happy Brain and Idiot Brain
