What nerves run down your thigh?
The femoral nerve is located in the pelvis and goes down the front of the leg. It helps the muscles move the hip and straighten the leg. It provides feeling (sensation) to the front of the thigh and part of the lower leg.
What is the difference between femoral nerve and obturator nerve?
Both these nerves arise from the lumbar plexus, which lies up here within the thickness of the psoas major muscle. The femoral nerve emerges lateral to psoas major, the obturator nerve medial to it. It runs across the iliacus muscle, and passes under the inguinal ligament just lateral to the femoral artery.
What area of the body does the obturator nerve serve?
The obturator nerve (Figs 6.15, 6.16) supplies all the muscles in the medial compartment of the thigh. It enters the thigh by passing through the obturator foramen accompanied by the obturator artery. As it goes through the foramen it divides into anterior and posterior branches.
What is obturator canal?
The obturator canal is a small opening in the superior aspect of the obturator foramen that connects the pelvis to the medial compartment of the thigh. The obturator foramen is otherwise covered by the obturator membrane.
What is a obturator in anatomy?
The obturator nerve is one of the largest branches of the lumbar plexus. It is a mixed nerve which arises from the ventral (anterior) rami of the spinal nerves L2-L4.
Which is the smallest nerve in human body?
Trochlear nerve
The trochlear nerve is unique among the cranial nerves in several respects: It is the smallest nerve in terms of the number of axons it contains….

Where is the obturator located?
The obturator internus is the deep muscle of hip joint which is part of lateral wall of pelvis. It is found in the superior inner side of the obturator membrane.
What is obturator jerk?
Electrical stimulation of the nearby obturator nerve during electroresection of lateral wall tumors can result in a powerful adductor spasm of the leg known as an “obturator jerk”. An obturator jerk during TURBT greatly increases the risk of bladder perforation.
What is the obturator membrane?
Medical Definition of obturator membrane : a firm fibrous membrane covering most of the obturator foramen except for the obturator canal and serving as origin of the obturator externus and obturator internus.
Where is the obturator membrane?
The membrane is attached to the sharp margin of the obturator foramen except at its lower lateral angle, where it is fixed to the pelvic surface of the inferior ramus of the ischium, i. e., within the margin. Both obturator muscles are connected with this membrane.
