- ⭐ Semimembranosus Muscle ⭐
💪 Origin: Ischial tuberosity
💪 Insertion: Medial condyle of the tibia
💪 Action: Flexes knee, extends the hip, medially rotates tibia when the knee is flexed
💪 Nerve: Tibial nerve of the sciatic plexus (L5, S1 and S2)
💪 Artery: Profunda femoris and gluteal arteries
The semimembranosus is one of the three hamstring muscles. The other two are the biceps femoris and semitendinosus.

👏👏 thank you for this clear explanation
Thank you. Cheers.
This muscle is very important to proper foot arch and pronation/supination dynamics. Recommend strict form single leg Romanian dead lifts with body weight to engage and activate the hamstrings. Too heavy weight will exacerbate preexisting issues with hamstring/glute weakness and low back/knee pain until satisfactory strength, mobility and flexibility is achieved from the glutes and hips down to the foot and toes
Great presentations, giving clear descriptions, explanations and clinical notes. I love the steady pace and helpful colours on the diagrams - thanks a million, Nayomi
Thank you so much! Glad you have found it helpful.
great sir
Thanks!
Thank you very much for all the information. Last week I was running a half-marathon and felt a sharp pain in the posterior side of my knee. Sports medicine doc told me that it was a hamstring issue. Is there a tendinopathy related to this muscle where it attaches near knee?
Glad it helped! Sorry to hear about your injury. It is possible that it could be a hamstring issue. If you have overly tight hamstrings, it increases their the risk of injury. It would be impossible to know exactly though without doing a full examination and using various movement tests. I'd suggest seeing a qualified physiotherapist for an evaluation, as they will be able to do those tests for you. Outside of the knee injury, they may also pick up on other mobility limitations during the examination, which will be helpful in preventing future injuries also.
@@BodyworksPrime thank you very much, I will definitely bear in mind your advice and see a physiotherapist as soon as I can (plus I've been in quarantine as I tested Covid positive right after the race!). All the best from Turkey
i did some aggressive hamstring/hip flexor stretches and now i feel a sliding/pop when i walk, behind my knee, right where this semimembranosus is. There's no pain or instability, but just an annoying pop/snap feeling at the end of the range of motion when my leg extends during walking. WHat's the treatment or issue? I know i have overly tight hamstrings. Should I continue some lighter stretches to rehab this area or complete rest?
Sorry to hear about your injury. The snapping/popping could just be connective tissue or a muscle in the area moving over the condyle of the femur or something else and creating a snapping sensation. Doing some light stretching could help if tightness is causing this. A way to tell if it will help is to do some light stretches and see if the increased range of motion improves the pop/snapping sensation. This will let you know if you're on the right track. Just make sure to not to be aggressive with the stretches, you can get great results from just a gentle stretch multiple times a day. If you're concerned about it though, a physiotherapist will be able to help. A physiotherapist will do a full investigation on the area and in my opinion be well worth the investment. Without doing a proper assessment, it is impossible to say exactly what the issue is.
@@BodyworksPrime would any physical therapist be able to diagnosis the issue? or need special certification? thanks.
@@TunesAndToys any decent MSK physiotherapist should be able to help. Personally I'd look for one that has some experience with treating athletes or sports injuries. But a regular physio would be able to help too, provided they are a good one. Just make sure they are an actual qualified physio and not a sports therapist or something else.
@@TunesAndToys I have the same problem, did you find out anything on how to fix this issue? Please anything helps..
@@mvpmatty8295 MRI found a baker's cyst behind the affected knee. All i can do is surgery now i guess. Not sure what caused it
