- ⭐ Iliocostalis Muscle Anatomy ⭐
The iliocostalis muscle has three sections, the cervicis, thoracis, and lumborum. It is also part of the erector spinae muscle group. The anatomy of the iliocostalis is below. Watch the full video for an in depth explanation.
💪 Origins:
🔴 Iliocostalis cervicis: angle of ribs 3-6
🔴 Iliocostalis thoracis: angle of ribs 7-12
🔴 Iliocostalis lumborum: medial end of iliac crest, lateral crest of sacrum, & thoracolumbar fascia
💪 Insertions:
🔵 Iliocostalis cervicis: posterior tubercle of the transverse process of C4-C6.
🔵 Iliocostalis thoracis: transverse process of C7 & angles of the ribs 1-6
🔵 Iliocostalis lumborum: transverse processes of L1-L4 & angles of ribs 4-12
💪 Actions:
🟢 Unilateral contraction: lateral flexion of the trunk/vertebral column & weak lateral flexion at the base of the neck (below C4)
🟢 Bilateral contraction: extends the trunk/vertebral column & weak extension of the base of the neck (below C4)
💪 Nerve:
🟣 Lateral branches of the posterior rami of the spinal nerves
💪 Artery:
🟠 Dorsal branches of the posterior intercostal, subcostal, lumbar & lateral sacral arteries

This comment applies to all 3 erector spinae muscle videos of yours.
THANK YOU SO MUCH! out of ALL the research that i've done on google and sometimes youtube i couldn't find ANY video or article that explained it in such DETAILED and ORGANIZED way. your videos has cleared out completely the mess and confusion that i had, and now i finally understand the nature of these complex muscle groups in a very comprehensive way thanks to that (again) detailed and organized way of explanation that you provided. So with that being said, mad respect, beautiful job, and THANK YOU SO MUCH!
Thanks mate :) appreciate the kind words! The erector spinae muscle group was by far the most challenging muscles I have done videos on. It took me a full week of solid research, digging through research journals just to get all the info ready (some ES sections aren't even mentioned in text books). Making the videos took even longer! So I can safely say the info is as accurate as you can get online. It's amazing to hear all that hard work has helped you, thanks for letting me know. Best of luck with the studies 🙌
@@BodyworksPrime Thanks, you're right about the fact that not all of that specific information is out there in the textbook so my research was very similar to yours HOWEVER the big difference is that my extensive research of digging and searching took me just a single few hours, and it's all thanks to your weeks of research lol XD it's a bit funny I know but that's the benefit of your work, you managed to share your knowledge in a very cohesive way to others.
I would also like to mention that during my research on the deep back muscles I have found two other groups deeper to the Erector Spinae, which are the Transversospinalis group and the Segmental muscles (AKA deep minor back muscles). and I'm mentioning that because if you thought that there is not enough detailed info out there on the erector spinae group, well there is way less specific info on these two other deep groups of muscles. and to make things even more complicated these two groups are inconsistent by there order and pattern. You probably know this but I'm just mentioning this for a possible next challenge (I'm doing this myself as well).
@@godev3r422 Thank you! I have been considering doing those other back muscles soon, but I think I still have PTSD from making the erector spinae videos 😂 jokes aside, they are to come 😁I want to cover everything eventually. Next few videos I am working on are going to be on the deep rotators of the hip joint, I may go back to the back after that though!
Clearly explained, great job 👍
Thanks!
You're amazing! Thank you
Thank you too!
Can you clarify that the iliocostalis lumborum insertion of angles of ribs 6-12 not 4-12?

Thank you.
Welcome!
would this action not elevate the illiac crest. Toward the ceiling if standing for example?
I would imagine it could assist in the movement of anterior pelvic tilt when acting on the pelvis, as that involves lumbar extension, if that is what you mean by elevating it? The movements listed in the video are all based on information provided in various textbooks and research papers.
