Neurology | Sacral Plexus

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds!
In this lecture Professor Zach Murphy will be teaching you about the sacral plexus. We go over the various branches of the sacral plexus, what structures are supplied by the those branches and clinical correlations associated with damage to the sacral plexus.
The sacral plexus is a network of nerve fibers that supplies the skin and muscles of the pelvis and lower limb. It is located on the surface of the posterior pelvic wall, anterior to the piriformis muscle.
The plexus is formed by the ventral rami (divisions) of the sacral spinal nerves S1, S2, S3 and S4. It also receives contributions from the lumbar spinal nerves L4 and L5. We hope you enjoy this lecture and be sure to support us below!

You deserve a million appreciation professor, I learned brachial plexus, muscles of the lower& upper limbs from your channel, you paved the way for my medical school. meet what you deserve on your way. I'm now your student full-time.

[@aleksandramaecka2834]

you are a great teacher. it does not even bother me, as it usually does, that it's a video and i cannot ask any questions..because I don't have to because you explain everything very thoroughly. it helps a lot that you repeat everything 2-3 times in a row. thank you!

28:00 before you get to the ,,last one" im pretty sure you forgot about the n. To Quadratus Femoris coming from L4, L5 and S1. It provides motor innervation to the QF m. and gemellus inferior m. Amazing video! Thank you for making it all so understandable!

[@wesleykhalil5006]

Awesome video! I have one Gripe. Zero chance of herniation effecting the sciatic nerve below L5 S1 IVD/ L5 Nerve. super common cause of sciatica is it being compressed by a hypertonic piriformis or in a subset of people where it actually runs through the belly of piriformis. Women during pregnancy is a super common time for women to get sciatica also.

So both the tibial nerve and posterior cutaneous nerve are supplying the posterior knee, sole of foot, calf and thighs?

[@stefaanluchian]

I think you forgot the nerve to Quadratus Femoris (from the ant div of L4-L5-S1). It supplies QF and GI (inf gemellus)

[@Medhammers]

i was wondering about that too

[@someone3164]

Doesnt it supplied by lumbar plexus ?i mean the femoral nerve ?

[@miguel-jj3ku]

@@someone3164 Quadriceps femoris(the main anterior thigh muscle innervated by the branches of lumbar plexus) is different from Quadratus femoris( a muscle in gluteal region innervated by branches of sacral plexus)

[@alexandrasantos8421]

Thanks very much for the video, it's going to save me on my anatomy test, just like your other videos have....I just have one question: if the tibial nerve innervates the posterior compartment shouldn't it be the posterior division of the sciatic nerve? And that way the common fibular nerve the anterior or even lateral division of the sciatic nerve?

You are really amazing🙏👍👍✌️✌️✌️
