Trapezius Muscle - Origin, Insertion, Actions - Human Anatomy | Kenhub

The trapezius muscle is a flat, triangular muscle and belongs to the superficial back muscles. It plays an important role in the shoulder and head movements and is innervated by the accessory nerve (CN XI). The muscle has a descending (superior), transverse (middle) and ascending (inferior) part with different origins and insertions that allow different types of movements.

The aim of this video is to teach you the most important anatomy facts about the trapezius muscle including its function, origin, insertion and innervation.

In this video tutorial, we cover the following aspects of the trapezius muscle:
0:15 nerve supply by the accessory nerve (cranial nerve XI)
0:28 origins and insertions of the muscle's 3 parts: descending, transverse and ascending part
1:03 functions of the trapezius in the shoulder: shoulder stabilization, elevation and depression
1:22 functions of the trapezius muscle in the vertebral column: lateral and dorsal flexion of the head

These videos are so helpful in studying for my personal training certificate with NASM. They provide a "moving visual" alternative to the texts in my textbook. THANK YOU!

[memo]

I wish if you show the movements in your videos, this will make the functions much clearer for us. great video though

[WendyB]

Nice video. It would be super helpful if you can show the actions in it as well.

[hagarahmed]

really you help me greatly in learning anatomy . i follow you from Egypt, thank you so much

[ggonsg]

Thank you so very much for all your help. Beautifully illustrated video!

[faysalabi]

Gotta show the movements my brother.. Or its no different than reading it somewhere. Thanks

[حسينعلاء-هزع]

You are so good, thank you for this video ❤

[sraddhar]

Thanks for releasing out more videos! Appreciate it!

[KhanBaba-ntij]

could you guys please write down the origin and insertion as well?

[ryanfrizzell]

Pull ups have really increased the size and strength of my trapezius muscle.

[AlligatorAli]

So if we strengthen trap muscle from laterally (from the sides), we can cure scapular winging ?

trapezius nerve supply is c3-c4, not c2 to c4

[jones]

I see all these comments about showing the muscle movement. Move your trapezius! He's just showing you the anatomy and the terms they use geez

[vaishnaviarya]

It could be much better if you add its origin and insertion!!

[darrylroland]

Without showing movement this is almost meaningless if you don’t know the vocabulary that is so casually tossed around.

[Harshalk]

Video title says Origin and Insertion, but that is not mentionedin the video

[Mr-Slayer-Sir]

I Pulled My Trapezium Muscle Because I Slept Wrong It Hurts Like Hell Also My Neck And Right Arm Is Fully Effected As Well. I Already Have A Load Of Health Issues. This Hurts And I Can Hardly Move Around.

bones and muscles are dependent on eachother for various actions

[zoomeraygun]

It would be great if you would show movements of the limbs to support what you are saying. Your terminology is very medical and If I could understand what you were saying I wouldnt really need to be watching your video. Seriously !!, make things simpler so that 90% of the population can understand you instead of 5%.

you really want us to believe this video was helpful
