The quadriceps femoris muscle is a four-headed muscle of the thigh which almost completely covers the femur. It ranks among the strongest muscles in the human body. It significantly forms the lateral contours and the ventral side of the thigh. Its innervation is carried by the femoral nerve. If we look closely, we can see that the quadriceps femoris can be split into 4 muscles: the rectus femoris muscle, vastus medialis muscle, vastus lateralis muscle, and vastus intermedius muscle.
The quadriceps tendon runs above the ventral side, and through the periosteum of the patella, and finally inserts at the tuberosity of the tibia. The part below the patellar apex is known as the patellar ligament. In terms of location, the quadriceps is considered to be one of the ventral thigh muscles. As for function, the quadriceps is the only extensor of the knee joint. It plays an important role in every movement involving the stretching of the knee. And in addition, it keeps the knee from buckling when standing.
On this video, we will cover the following points about the quadriceps femoris:
0:05 general anatomy of the quadriceps femoris
0:56 rectus femoris muscle
1:17 vastus medialis muscle
1:47 vastus lateralis muscle
2:14 vastus intermedius muscle
2:48 quadriceps tendon
3:08 quadriceps femoris functions

i dont mean to be offtopic but does anybody know of a method to log back into an Instagram account?
I stupidly lost my account password. I would love any tips you can give me.
@Atticus Johan Instablaster ;)
@Houston Zechariah i really appreciate your reply. I got to the site through google and im in the hacking process atm.
Seems to take quite some time so I will get back to you later when my account password hopefully is recovered.
@Houston Zechariah it worked and I now got access to my account again. I'm so happy:D
Thank you so much you really help me out !
@Atticus Johan glad I could help =)
As somebody who is training to become a personal trainer, the amount of anatomy I have to learn feels overwhelming. This channel seems like a great place to casually pick stuff up in digestible chunks. Thank you very much
Thank you so much for the kind words!
Watching this before leg day.
Bless Dead Hands bahahaahah
Watching this to figure out which quad muscle i just put through the shredder.
Turns out it was the Vastus medialis which explains the confusion i had about the pains area.😂
Thank you very much!
i'm probably gonna have to watch this video like 50 times.
Agreed!
thanks, very helpful
Great video! Very educational.
plese visually show the origin and insertions point
Hi there! Throughout the video, you can find a lot of information about the origins and insertions of the different muscles. There's also always an illustration showing the muscle and its origin and insertion points. For more detailed illustrations of these bony structures feel also free to take a look at our anatomy atlas at Kenhub. We offer thousands of high-quality illustrations of all anatomical structures there and it's completely for free :)
Thank you so much, I've been recently Diagnosed with aiis tendopathy. This explains in brief what's going on with me. Any chance to share some basic rehab exercises for rectus femoris? Cheers
Thank you so much my understanding of the topic has increased so much
We're so happy to hear that :) Have fun learning!
Thanks ....... it helping me allot ❤️
It very helpful
Thanks :)
thank u so much for this video and your videos are awesome.i always prefer to watch your videos before reading books thanks once again
You're welcome and thanks for your kind words :)
i also watch these videos before reading..thank you so much
Superb
I have right sided hip aches and recently started having pain in my right knee. Both feel a lot better after a stretch. Since then I have been walking/running an average of 9km 4-6 days a week and as a result I have now gotten rectus femoris tendinitis. Very painful. Obviously it's my hip causing this problem, but its so hard to get good help about these issues. Really tough situation.
easy and simple
Awesome
very informative!
We're happy to hear that you enjoyed our video :) Have fun learning!
yeah i got that
Correct me if I am wrong, but the articularis genus muscle is not a split-of of the vastus intermedius. In the video, they state that this is the case.
Thanks... I got sleepy though.. hehehe.. too much jargon.. :)) But i'll save this for future
i love the video
Thank you! So glad you liked it. We are publishing new videos on our website every week. Hope to see you there!
I thought I had pulled a Kevin Nash but it was just strained. Thank God
luv it
+Misha Jordan Thanks, Misha!
Nice
can u make a video on great sephanous vein and inguinal ligament
Hi Abhishek! On our website www.kenhub.com we already offer a video about the neurovasculature of the hip and thigh (including the saphenous nerve) and also one about the inguinal canal. Could that be interesting for you? If so we'd be happy to welcome you at Kenhub! Just give it a try and see for yourself :)
Yes . I have fractures Condylis medialis femoris decstra.
We're sorry to hear that and wish you a speedy recovery! If you want to find out more about the anatomy of the femur you can find several matching learning materials on our website www.kenhub.com. See you there :)
At 2:35 he is talking about the articularis genus, not the vastus intermedius. I was confused at first because the graphic and the heading refer to the vastus intermedius while he talks about the articularis genus.
Dear Eric,
The separate attachment of the vastus intermedius at the knee joint capsule is referred to as the articularis genus. But you are right that nowadays many (if not most) anatomists suggest that this part is its own entity. There are wonderful cadaver studies about the articularis genus, e.g. Woodley et al. (2012), that explain the course and function of this not well studied muscle.
Thanks for clearing that up! :-)
Thanks for adding this info. I didn't know about the current common terminology. Just wanted to make sure people knew which structure this statement was about: "Even though it does not count as an independent muscle, it is sometimes considered as the fifth head of the quadriceps". Thanks for making these quality videos.
Dear Eric, I agree with you, the sentence could be misleading with the image of the intermedius on the left. I'll make a suggestion for the team to change it to "Even though the articularis genus muscle does not count [...]" Cheers :-)
Thank you for sharing this video. Very well-explained. But if you are willing to look for further information about human anatomy and physiology, try to search it on google. There, you can find as much information as you need. I highly recommend "Grathaw Simple Anatomy Expert".
Great
Thanks for your kind feedback :)
I get it now fanks bruv $
external and internal rotation of knee joint or hip joint?? :) my knee doesn't want to perform any of that :)
Dear Magdalena,
Rotation of knee only works when the joint is flexed. If it is fully extended (e.g. when you are standing) the collateral and cruciate ligaments are too tight to allow any rotation movements. Flex your knee in a 90° angle and you'll see how you can rotate the knee inwards and outwards about 25° :-)
yes it will, or else you couldnt walk 😂
Wow
i had practiced too much workout . which vastus intermedius muscle rupture since three or fourth months before now , and i take one month rest and it s repeat feel bad . take one month and repeat again and again . i see a doctor and he just give me a leg protector . any solution please !
Dear Mohamed,
We are sorry to hear about your medical condition. If it is still painful after 3-4 months, one need to consider a more serious cause such as a complete tearing or an avulsion rupture at the bone. An MRI might be needed for the exact diagnosis.
Wish you all the best!
thank you very much for your help , exactly what you said )) the same spelling of another doctor told me now ^^ , happy to follow your channel and see more another beautiful videos .. thank you again ^^
THis is the intro of the Humanist Report...
🍕🇮🇸🇮🇸
a good video but extremely irritating the way the text covers the muscles as shown in green ! !
Thanks for your feedback! We're sorry to hear that you found our green highlighting of the muscles confusing. As all the muscles are shown in red we decided to mark the specific muscle the video is talking about in green so you can identify it easily.
Kenhub you misread me ... the colouring is fine what is annoying is the fact that the TEXT OBSCURES part of the illustrations , regardless of colour
Thanks for the clarification! I will gladly forward this aspect to the video team at Kenhub so they can keep it in mind for the future :)
Awesome
