Where does the sciatic nerve exit?
The sciatic nerves exit the pelvic bone through an opening (greater sciatic foramen) to emerge in the buttock.
Which nerve belongs to the peripheral nervous system A. Sciatic nerve B. Vagus nerve C. Optic nerve D. Trigeminal nerve?
sciatic
What permits passage of the sciatic nerve?
The sciatic nerve passes through the greater sciatic foramen, which is an opening in the pelvis formed by the ilium, ischium, and sacrum. It typically exits the pelvis below the piriformis muscle, although variations exist where it can sometimes pass above or through the muscle. This pathway allows the nerve to travel down the posterior aspect of the thigh and into the leg.
Does the sciatic nerve pass through the lesser sciatic foeamen?
If you look up the nervous system there are 3 places in your lower back that cause Sciatic or pinched nerve in three locations. Lower lumbar back at 3,4,5, cause pain in the left or right backside cheek, a shorter nerve. One causes pain that comes into the groin are from the backside around and up through groin. One causes the pain that runs down the outside seem of your pants and can end of in the second little toe. (next to the pinkie toe) It is called the Sciatic nerve.
What happens if you get near a nerve giving an buttocks injection?
The femoral nerve.
Would biceps femoris be paralyzed if the sciatic nerve was severed?
yes
What muscle in the buttock crosses the sciatic nerve?
The piriformis muscle crosses the sciatic nerve in the buttock region. Compression or irritation of the sciatic nerve by the piriformis muscle can lead to sciatica symptoms like pain, tingling, or numbness in the buttock and down the leg.
Why does the gastrocnemius muscle contract after stimulating the sciatic nerve?
The gastrocnemius is stimulated by a branch of the sciatic nerve called the tibial nerve. This causes contraction and produces plantar flexion of the foot. When a person stands on their "tippy toes" that is plantar flexion. This is a function of this nerve.
Which muscle is anatomically closest to the sciatic nerve?
hamstring
What muscle does the sciatic nerve pass through?
M. Piriformis
What is the effector of the Achilles reflex?
gastrocnemius muscle
Where does the sciatic nerve exit?
The sciatic nerves exit the pelvic bone through an opening (greater sciatic foramen) to emerge in the buttock.
Under which gluteal muscle does the sciatic nerve lie?
Gluteus maximus
What muscle will not paralyze when the facial nerve is severed?
Buccinator and masseter
What can cause back pain besides muscle tear or spasm?
Pinched nerve .Or sciatica, an inflammation of the sciatic nerve.
What major nerve innervates the extensors of the leg?
The sciatic nerve is the major nerve that innervates the extensor muscles of the leg, particularly the tibialis anterior muscle. It is a large nerve that branches into the common fibular nerve and the tibial nerve, both of which supply various muscles in the leg.
Which nerve belongs to the peripheral nervous system A. Sciatic nerve B. Vagus nerve C. Optic nerve D. Trigeminal nerve?
sciatic
