The nerve exits the pelvis through the C. Innervation. The superior gluteal nerve is the term used to describe the nerve near the upper pelvis that comes straight out of both the fourth and fifth lumbar nerves (the back sections), as The gluteal region, or buttock, is bounded superiorly by the iliac crest and inferiorly by the fold of the buttock, The region is largely made up of the gluteal muscles and a thick layer of superficial fascia. It innervates the gluteus medius (upper branch), and gluteus minimus and tensor fascia lata muscles (larger Artery. Action: Powerful abductors of the thigh. For example, when you realize that the radial nerve innervates the majority of the hand and wrist extensor muscles, you can form better associations and quickly reference this knowledge when youre tested on it during anatomy lab or an exam. The superior gluteal nerve innervates the gluteus medius and the gluteus minimus. The seven deep gluteal nerves all originate via the lumbosacral plexus or sacral plexus, all exit the pelvic region through the greater sciatic foramen and with the exception of the superior gluteal nerve, all travel through the infrapiriform foramen (inferior to the piriformis) to innervate gluteal regions or other inferior structures. The superior gluteal nerve (L4, L5, S1) innervates this muscle. It arises from L4 through S3. Let's start off with the cluneal nerves which innervate the skin of the gluteal region. It is located posteriorly to the pelvic girdle, at the proximal end of the femur. The radial nerve innervates the long head of the triceps muscle and sends a posterior brachial cutaneous branch to the skin covering this muscle. Heres the sacral plexus. Sensory innervation Skin of buttock Motor innervation Gluteus Medius, Gluteus Minimus, Tensor Fascia Lata This is the sciatic nerve. The gluteus maximus is normally active only when the hip is in flexion, as during stair climbing or cycling, or when extension of the hip is resisted. The superior gluteal nerve (L4, L5, S1) also innervates the gluteus medius and gluteus minimus muscles. 4 Identify the boundaries and contents of the popliteal fossa. The superior gluteal nerve is
