Muscle Spindles: Innervations and Alpha-Gamma Coactivation

How does hair-pulling relate to alpha-gamma coactivation in muscles? In this video, I give an overview of muscle spindles and their innervations. Through various examples, I explain the components of a muscle spindle, the types of information that are picked up by sensory nerve fibers, and the difference between nuclear bag and nuclear chain fibers.

When I look for explanation videos, I normally have to pause, go back, and try again to understand but this was SO clear. I couldn't figure out for the life of me how alpha-gamma coactivation worked but you did a great job w this!

The alpha-gamma coactivation explanation at the end is great, just what I was looking for

[rkaur]

Watch til the end, that last part about alpha-gamma coactivation is essential. Also LOVE the analogy, wish these videos were out before, is there anyway to be a part of the team!?

[debrah]

This is such an amazing explanation/video. It's clear and concise while giving all the right details. I don't have to find another video to fill in any gaps and I don't feel like I'm wasting my brain/time with outside information that is mildly relevant to the topic ( especially when I'm just trying to learn the foundation). Thank you!!!

[ahmadhafizan]

i love you so much thank you so much for explaining this ESPECIALLY THE COACTIVATION PART at the end I was trying to understand how it works

[Bomgenie]

thank you so much, I was having a hard time understanding the coactivation of muscle spindle and after watching this video finally got fully understood

[Lili-vhnx]

This is so well explained and so aesthetic, too! Thank you very much

Hello BioMe handler/teacher/tutor. I just want to thank you because you helped me a lot in understanding the reflexes! I’m a visual learner and I kind of got the hang of this certain topic an hour before our exam last week and it’s all thanks to you! I hope that your channel would have more subscribers because you deserve it~ 💗
