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 nerves run through the hip joint?
The main nerves in the hip region include the femoral nerve in the front of the femur and the sciatic nerve at the back. The hip is also supplied by a smaller nerve known as the obturator nerve. In addition to these nerves, there are blood vessels that supply blood to the lower limbs.
Which spinal nerve serves the front of the thigh and leg?
The femoral nerve is the major nerve that serves the tissues of the thigh and leg, including the muscles and skin. While the much larger sciatic nerve also passes through the thigh on its way to the lower leg and foot, only the femoral nerve innervates the tissues of the thigh.
What are the two main nerves of the hip?
All of the nerves that travel down the thigh pass by the hip. The main nerves are the femoral nerve in front and the sciatic nerve in back of the hip. A smaller nerve, called the obturator nerve, also goes to the hip. These nerves carry the signals from the brain to the muscles that move the hip.What is the cauda?
Cauda is Latin for tail, and equina is Latin for horse (ie, the “horse’s tail”). The CE provides sensory innervation to the saddle area, motor innervation to the sphincters, and parasympathetic innervation to the bladder and lower bowel (ie, from the left splenic flexure to the rectum).
What is saphenous nerve?
The saphenous nerve runs laterally alongside the saphenous vein, giving off a medial cutaneous nerve that supplies the skin of the anterior thigh and anteromedial leg. The saphenous nerve travels to the dorsum of the foot, medial malleolus, and the area of the head of the first metatarsal.
What is Ilioinguinal nerve?
The ilioinguinal nerve originates from the first low back (lumbar) spinal nerve. This nerve wraps above the upper ridge of the hip bone and travels into the groin. It provides sensation to the upper inner thigh, groin, and perineum.
What are the phrenic nerves?
The phrenic nerve originates from the anterior rami of the C3 through C5 nerve roots and consists of motor, sensory, and sympathetic nerve fibers. It provides complete motor innervation to the diaphragm and sensation to the central tendon aspect of the diaphragm.Where does the femoral nerve run?
The femoral nerve begins its course in the abdomen, by passing through the psoas major muscle. It then traverses laterally to the distal part of the psoas major muscle, and then finally, it runs “sandwiched” in between the iliacus muscle and the psoas major muscle.
Why femoral nerve is outside the femoral sheath?The femoral nerve is the largest branch of the lumbar plexus. … The nerve enters the femoral triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, it lies outside the femoral sheath, gives off articular branches to the hip and knee joints.
Article first time published onWhat nerve Innervates vastus lateralis?
The vastus lateralis is the largest of the quadriceps muscles. It receives motor innervation through a branch of the fem- oral nerve, namely the MNVL.
What does the femoral nerve split into?
In the proximal thigh, the femoral nerve divides into sensory branches, which innervate the upper and anterior thigh, and muscular branches, which innervate the quadriceps. One of the major branches is the lateral femoral cutaneous nerve.
What is sural nerve?
Introduction. The sural nerve is a cutaneous nerve, providing only sensation to the posterolateral aspect of the distal third of the leg and the lateral aspect of the foot, heel, and ankle.
What nerve Innervates front of leg?
The anterior compartment is innervated by the femoral nerve which has two major branches, the anterior and the posterior.
What nerve supplies the anterior thigh?
The femoral nerve innervates the sartorius, pectineus, and quadriceps femoris, and iliacus muscle of the iliopsoas. It receives nerve supply by the nerve roots L2 through L4, innervating both the hip flexor and quadriceps muscle groups. The femoral nerve is also responsible for anterior thigh and medial leg sensation.
What is cord equina?
The corda equina carries nerves which control the bladder and bowel. The cauda equina also carries nerves which control movement of the legs, and nerves which sense light touch and pain in the legs or around the back passage (perineum).
Is cauda equina CNS or PNS?

What is saddle anesthesia?
Saddle anaesthesia refers to reduced sensation in the area that would be in contact with a saddle if sitting on one. This includes the perineum, buttocks, anus, groin and upper thighs. Saddle anaesthesia will make these areas feel numb and abnormal.
Is ilioinguinal nerve a peripheral nerve?
Both the iliohypogastric (IH) and ilioinguinal (II) nerves arise from the first lumbar nerve (L1) on each side of the body. The ilioinguinal nerve is a smaller nerve and courses below the iliohypogastric nerve.
Does ilioinguinal nerve enter deep ring?
At the anterior end of the iliac crest the ilioinguinal nerve pierces the transversus abdominis and internal oblique muscles to enter the inguinal canal from the side, not through the deep ring.
Where is ilioinguinal nerve located?
The ilioinguinal nerve is a branch of the first lumbar nerve (L1). It separates from the first lumbar nerve along with the larger iliohypogastric nerve. It emerges from the lateral border of the psoas major just inferior to the iliohypogastric, and passes obliquely across the quadratus lumborum and iliacus.
What travels with the great saphenous vein?
It then runs upward in the thigh and passes over the medial surface of the thigh. In the thigh it is accompanied by branches of the medial femoral cutaneous nerves , and at the knee, in the leg and the foot the vein is closely related to the saphenous artery (a branch of the descending genicular artery).
What is superficial peroneal nerve?
The superficial peroneal nerve (superficial fibular nerve) is a mixed nerve that carries sensory information from the anterolateral aspect of the leg and the greater part of the dorsum of the foot (except for the first web space).
Is the saphenous nerve a branch of the femoral nerve?
The saphenous nerve is the terminal branch of the femoral nerve. The nerve becomes superficial at the medial border of the knee joint as it pierces the fascia between the gracilis and sartorius muscles. It runs distally in the cleft behind the medial border of the tibia just posterior to the great saphenous vein.
What type of nerve is femoral nerve?
The femoral nerve is a mixed nerve of the lower limb that innervates the muscles and skin of the hip and thigh. The femoral nerve originates from the lumbar plexus, arising from the anterior rami of spinal nerves L2-L4. In fact, it is the longest branch of the lumbar plexus.
Where does the saphenous nerve run?
The saphenous nerve runs posterior to the greater saphenous vein in the leg and divides into an anterior and posterior branch approximately 3 cm proximal to the tip of the medial malleolus. These branches terminate in the integument proximal to the tip of the medial malleolus, while the vein continues into the foot.
What nerves make up femoral nerve?
The femoral nerve is the major nerve supplying the anterior compartment of the thigh. It is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2, L3, and L4).
What is an axillary nerve?
The axillary nerve arises from the fifth and the sixth cervical nerves that is C5–6. The axillary nerve is a branch of the posterior cord. It is found anterior to the subscapularis, posterior to the brachial artery, and lateral to the radial nerve.
What are the vagus and phrenic nerves?
The phrenic is the motor and sensory nerve of the diaphragm. The vagus provides the parasympathetic supply for all the organs of the thorax and abdomen. The courses of these two nerves are similar: they both start in the neck, run downward in the mediastinum, and pass through the diaphragm.
Where does the phrenic nerve travel?
In humans, the right and left phrenic nerves are primarily supplied by the C4 spinal nerve, but there is also contribution from the C3 and C5 spinal nerves. From its origin in the neck, the nerve travels downward into the chest to pass between the heart and lungs towards the diaphragm.
What pierces the femoral sheath?
The femoral branch of the genitofemoral nerve courses through the lateral compartment of the femoral sheath and pierces the anterior surface of the sheath. This nerve innervates the skin of the anterior thigh, just above the femoral sheath.
