Which nerve lies deep to the sciatic nerve in the gluteal region?
Ahmadbtm
The sciatic nerve is the largest nerve in the human body, originating from the lumbosacral plexus (L4-5 and S1-3) and providing sensory and motor innervation to the lower extremity. The sciatic nerve exits the pelvis via the greater sciatic foramen below the piriformis muscle. In the gluteal region, the sciatic nerve courses between muscle layers. The nerve is deep (anterior) to the gluteus maximus muscle and is superficial (posterior) to the inner muscle layers (superior and inferior gemellus muscles, obturator internus muscle, quadratus femoris muscle).
It courses down the midline of the posterior thigh and branches into the tibial and common peroneal nerves usually in the popliteal fossa. Sciatic nerve block is most commonly performed for foot or ankle surgery

How do you palpate the sciatic nerve?
The best place to palpate the sciatic nerve is deep in the buttock. It exists the pelvic area just under the piriformis. If you place your foot on a chair and find the ischial tuberosity (the butt bone - the ones we sit on) and move laterally, you will be on or near the sciatic nerve.
Where in the body is sciatic nerve located?
The sciatic nerve is the largest single nerve in the human body; it runs from each side of the lower spine through deep in the rear and back of the thigh and all the way down to the foot, connecting the spinal cord with the leg and foot muscles.

Are there any stretches that will help my sciatic nerve pain?
Traditional exercises and home treatments don't work because they fail to fix the physical problem and only provide temporary relief. Sciatica is just a symptom of something affecting your sciatic nerve to cause the pain and discomfort. A chiropractor can help get to the root of the problem and help align your body correctly to prevent the pain from reoccurring.
What is the prime mover of hip abduction?
In the canine: the gluteal muscles (superficial, middle, deep).
Where is the gluteal region of the body?
PCH Answer: The Buttocks Gluteus maximus is the largest and most superficial muscle in the buttock. It is attached to the Ilium bone( part of the pelvis), the Sacrum, the side of the Coccyx via the Sacrotuberus ligament and apponueroses ( the Gluteal apponeurosis and the Erector spinae). The muscle fibres pass down at an angle and attach to the Iliotibial tract of the Fascia Lata, the deep fibres of the muscle attach to the Gluteal tuberosity of the Femur.
What is sciatica and how does cause pain in my legs?
Some sources of sciatica are:Lumbar disc - this includes disc protrusion that compresses the L4 or L5 nerve root as it exits the spine. The outer fibrous layer of the disc weakens with wear and tear and eventually allows the inner jelly-like nucleus to bulge out and irritate the nerve root. The presence of a disc protrusion can be confirmed by specialised imaging such as CT scan or MRI.Lumbar joints - in some cases misalignment of the spine causes inflammation, irritating the nerve roots and producing sciatica. Your chiropractor will perform tests to determine if the sciatica pain is more disc or joint related.Muscular - the sciatic nerve passes through, or in front of, the piriformis muscle, deep in the buttock. Spasm of this muscle due to pelvic imbalance can compress the sciatic nerve - a condition known as Piriformis Syndrome.Only rarely is sciatica caused by serious pathology that requires medical referral. The majority of sciatic cases respond well to chiropractic care and specific exercises.Read more on this topic here...http://onewaychiropractic.com.au/archives/1773

What are 2 muscles in your back leg?
Semitendinosus and Semimembranosus are the most caudal and deep muscles Semitendinosus: Origin- ischiatic tuberosity; insertion medial surface of the body of the tibia and tuber calcanei (and crural fascia); innervation - sciatic nerve Semimembranosus: Origin- ISchiatic tuberosity; Insertion- distal medial lip of the caudal rough surface of the femur, and proximal end of the tibia; innervation- sciatic nerve The biceps femoris is the most lateral, and the adductor is the larges medial muscle
