Usually we think that the origin of the rectus femoris (the superficial quadriceps muscle) is the anterior inferior iliac spine, but did you know that this muscle also has another reflected head? This secondary head connects into the labrum of your acetabulum ~ your hip socket!
In this video, Gil demonstrates on models both of these origins sites for the rectus femoris to better illuminate our understanding of integral anatomy and movement.
To learn more about the quadriceps, check out Course 8 of "Anatomy from A to Z: Anterior Leg," at www. gilhedley.com where Gil does a deep dive through cadaver dissection into the quadriceps.

Gawd! I love your teachings!!!! It's important so I really love my body and help others w their bodies too. You're a humdinger.
Thank you kindly Cynthia, I have fun sharing, and I love hearing that the content is of service :)
Thank you a million times over for sharing your insights. I'm thoroughly enjoying your videos and will plan to take your courses.
You are most welcome Michael, it is very gratifying to connect with you and your interest!
Thank you for joining the growing number of therapists/teachers worldwide who are waking up to the realization that what we were taught in school for our formal education (which allowed us to pass the test to get our piece of paper in order to better guarantee that we would "do no harm"), may have been just a crock, and most likely/perhaps, in considerably more specific cases than just this. I also appreciate your consistent distinguishing between the words "muscle," "muscle fibers," and to be more specific "muscle fibrils." Too often our education gets in the way and I wonder how many times would dissection have to be done to come to a knowledge of reality IF we had not been taught, as in this case, something that was false or at best misleading. I remember numerous times during my training 25 years ago that I would palpate something similar to an issue like this and come up with something different than what the teacher said we were "supposed" to find. It makes me wonder if there is not something even more questionable about the amount time we spend studying muscle origins and insertions. In the vast majority (if not all) I have seen no change in the "muscle approach" emphasis in the curriculum of numerous students I have talked with about this in the last 20 years. That only leaves about 482 other examples to elucidate. BTW has anyone ever seen a COD (Cause of Death)
due to someone's ill-placed origin or insertion? Kinda makes one stop and think a bit, eh?
Haha very true Barry! And indeed I offer literally hundreds of challenges to the standard curricula in my Anatomy from A to Z project on my website, as we are much in alignment on the need to go a bit deeper than the simplifications manufactured for tests and initial studies if we want to develop ourselves as therapists and servants of the actual body as opposed to the body stylized for the books and tests~ Thanks for watching and sharing!!
Thanks for this information; it explains why my client with hip arthritis got much better after I worked intensively the rectus femoris. I am a rolfer.
Ahh that's great I'm glad to hear that helps, I discovered this too late to apply to my old Rolfing clients, I'm glad you are still at it, that is good work!
Excellent. As always!
Thank you Karena!
Gil, you have to be one of my favorite people I must say!
Thank you for this. Very helpful for treating those with long term undiagnosed labral injuries. I have to do an inventory of tissues that were subsequently injured by overuse as compensators
Hi Orthobio! You might find the actual dissection of the reflected head to be of keen interest, do so on camera very clearly in Course 8 of the Anatomy from A to Z project within the Inner Space Library of Explorer subscription members on my website. Very low-bar price point for entry for professional content, come on by! I appreciate your comment and thank you for watching :)
Thank you Gil, I appreciate the way you slow down and define words parts and your vulnerability and personal reminders to never stop learning.
Thank you for your interest and generous appreciate, sincerely!
Love the blooper at the end!!
Haha me too :) Nice editing job!
I will not comment each vidéo but i must say I really appréciate your work and way of teaching. I could spend all Day learning and it must be amazing to do so at the lab. Many thanks, again, to share with passion.
Thank you very much for this kind comment, enjoy!
Thank you for clarifying Gill, priceless info!
Thank you Angelika, I'm glad to know the clarification is useful to you!
thank you so much
Awesome… thanks brother Gil!
WOW! my learned gem for today. Thanks Gil!
Fascinating! Thank you!
You're welcome Erin, thanks for your interest!
You are making me smarter. I like working on the reflected head and it groups with complex hip anterior rotation. TFL quad origin...
The story in the reflected head.....
Awesome video! Thank you so much Gil! Kind regards.
Thank you 🙏🏼
You are most welcome, thanks for watching!
شكرا لك, شرح جميل
على الرحب والسعة ، شكرًا لك على المشاهدة!
specify is everything!
Indeed!
Hey Gil, Many thanks - these are such a friendly way for revision of old to new paradigms. Question - THR using the posterior lateral approach: will the Reflected Head of the Rec Fem be removed/dissected/reduced?? I wonder with rehabing for patients post op and then what goes on in Pilates classes when small range movements are done in large repetitions. Cheers 😉
That is a great question Paula! In my Anatomy from A to Z course 8 in the Inner Space Library of the Explorer subscription, one of the donor forms featured did in fact have a total hip replacement, and the reflected head was intact (hats off to the surgeons!). Now I want to pay more attention to this in those cases, and will keep my eye out to see if other instances work out differently, thank you for raising this interesting issue!
Excellent video. Really appreciate the 3d models.
I love to play with models to explore access to info, you might enjoy my vid on the knee too Kieran! czcams.com/video/zWbHAq0HRmQ/video.html
Thank you Gil!! I hope some day to get into the lab again with you!
Come on back when the timing's right Laura, I have a great team in CO Springs holding space for workshops!!
Hi Gil! Thank you for this visual. Just wondering if you also encountered the 3rd head - in your dissections - that (seems to) expand and 'merge' with the tendon of the glut minimus?
Hi Gil! Thanks for this. I’ve suspected that there was a more robust attachment superiorly. 1 straight line attachment did not seem strong enough. Have you obseved horizontal striations in the fascia over that flexion area? I’ve been wondering about those, too.
Hi Juliet! There is a "grid" in the dense fascia over that area at the most external level, though I wouldn't directly correlate that pattern to the underlying reflected head of rectus femoris, given the same pattern exists in many locations and is often characteristic of the dense regular fibrous fasciae! Thanks for watching and for joining in here Juliet, more to come :)
How would this effect the recovery after hip replacement surgery?
Another possibility when the client says " I have a pain in the groin." Seems to be most palpable wit internal rotation during straight knee flexion of the femur.
this is great and insightful! I have had an issue in the reflected head "zone" since having my hip replaced a year ago as an LMT the only way I've calmed it is by xxf that area...helps to have this as a reminder!
Wonderful! And best wishes on a speedy rehabilitation :)
It's interesting. There were reports that there were actually five heads of "quadriceps". If we count this reflected head, it should be six heads.
Hi Dr. Carlson, welcome back, I appreciate your interest. In Course 8 of the Anatomy from A to Z project in the Explorer subscription on my website I actually dissect very clearly on camera the so called "tensor vastus intermedius" (which was the subject of interest when all the hoopla around a "fifth quad" came out, as well as the reflected head of the rectus femoris. Utimately, the number of "heads" are a matter of tradition and cutting conventions, and what I enjoy most is paying attention to what's actually "there," and after that exploring how best to box it up and chat about it :) Thank you for watching, and for bringing this issue into the conversation, fun!
@@gilhedley449 Totally agree with you. Thanks for showing us your hard work, and our knowledge is evolving too.
Thank you, that's awesome! When we talk about myofascial meridians, what would you say to which muscle or tendon does the reflected head of the rectus femoris connect? Gluteus minimus?
How wonderful to have been able to isolate this dense, oft-activated bunch of fibres that I admit I have always allowed my brain to group into 'the hip complex' as none of my traditional anatomy teachings had provided me with any more specificity than that. DO you have any pondering on the function of this reflected head portion of the muscle unit? Stability is the first thing that springs to my mind, especially considering the grid structure of the fascia there that you mentioned in the comments below. Could there be any other functions, do you think?
Do you know if this is damaged in a total hip replacement?
Hi Gil,
I need a bit a break...... Oh my bones
Need this
Marguerite Belfast Ireland love luck and laughter 🇮🇪❤️🍀😜🐍✨🇮🇪
Haha easy does it M!!
I found it... Lol
Well that's just fascinating within itself thank you..
But even more interesting when it comes to associations of parkinsonism..
This area you are speaking about, is often affected and a person can often seemingly appear to be "leaning on one hip," with one bum cheek predominantly sitting back further than the other, when in standing position..
With those types of illnesses, really have to work on 'stretching out the fuzz' each morning or can become even stiffer.
Generally a routine of exercise is recommended to keep things agile. But I'm wondering at this stage if some physical Physiotherapy in that area would be beneficial..
It can often feel like stiff bones and perhaps it is. It would also make sense that the anatomy around the bone structure, would be restricting movement..
Speaking of interesting femur bones.. I'm hoping you can open the below link, to look at a very interesting bit of natural Alchemy..
I was thinking, if a meteor landed on Earth and wiped out herds of dinosaurs, then burying them, perhaps it sheds a whole new light on the mining industry.
Coprolites is an interesting subject on its own. (I mean, that's a whole lot of 💩 harvesting)
Every single thing that's lived, is interesting with itself.. the human body, is naturally one of the most interesting to our minds, it seems...
Humorous to my mind,
Imagine if somebody dug up a beautiful orange crystal, then had a necklace or ring made out of it, only to find out it was part of 'GreatGrandma's leg' further down the track!🤣🤣 Grins, that would actually be kind of cool too! 🧐
www.thefossilforum.com/index.php?/topic/38330-petrified-bone-with-orange-mineral-in-the-marrow-what-is-it/
That's a fun link Ral, cool stuff there! That actually might be the top of a tibia rather than the femur, I'm not sure we are looking at the greater trochanter, but possibly one of the condyles is worn making it look imbalanced. At center that looks like the tibial tuberosity to me, though not human, as the quads would be massive if it is indeed the tibial tuberosity...just spitballing here, it would be easier if in hand!
@@somanaut even after the flesh has gone from the bone, the marrow becomes a true piece of work within itself.
Queen Elizabeth might have part of a dinosaur leg amongst her crown jewels and not even know it🤔😂🤣 the human body is intriguing, even after most of it goes to decay (after we carc it!)
Hey Gil, What book did you use to find where the large chunk of tendon (reflective head of rectus femoris) come from?
My favorite text is the human body, I have dissected hundreds of them, and they are always correct in their presentation, though I cannot say the same for books haha!
ouch! I found mine
Haha don't dig TOO hard Lydia! Thanks for watching :)
