Which muscle is innervated by the femoral and obturator nerve?

Which muscle is innervated by the femoral and obturator nerve?

pectineus muscles
Anatomical Variations. In rare cases, the anterior division of the obturator nerve provides motor function to the pectineus muscles, which is typically innervated by the femoral nerve.

Which muscles are innervated by the femoral nerve?

The motor branches of the femoral nerve are the nerve to pectineus, nerve to sartorius and muscular branches to the quadriceps femoris. They innervate the flexors of the hip (pectineus, iliacus, sartorius) and the extensors of the knee (quadriceps femoris).

What muscle is not innervated by the obturator nerve?

adductor longus, adductor brevis, adductor magnus, gracilis) and the pectineus (inconstant). It is, notably, not responsible for the innervation of the obturator internus, despite the similarity in name.

What Innervates obturator Externus?

Innervation. Obturator externus is innervated by the posterior branch of the obturator nerve (L3 and L4), originating from the lumbar plexus.

Does the obturator nerve innervate the hip joint?

Local Anatomy The anterior branch of the obturator nerve innervates the adductor longus, adductor brevis, and gracilis muscles, as well as giving innervation to the hip joint.

What is the function of the femoral nerve?

The femoral nerve is the largest nerve of the lumbar plexus. It forms from the dorsal divisions of the L2-L4 ventral rami. [1] It has a role in motor and sensory processing in the lower limbs. As a result, it controls the major hip flexor muscles, as well as knee extension muscles.

What muscles are innervated by obturator nerve?

The obturator nerve can become entrapped as it passes through the obturator canal. The anterior branch of the obturator nerve innervates the adductor longus, adductor brevis, and gracilis muscles, as well as giving innervation to the hip joint.

What is the function of obturator Externus?

The mechanical model demonstrated that the primary action of the obturator externus muscle was to externally rotate the femur when the hip was in neutral position and flexed at 90°. Its secondary function was as an adductor when the hip was in flexion.

What muscles does the obturator nerve innervate?

What to do for obturator nerve injury?

  • doctors may sometimes go for decompression procedure of the obturator…
  • Spinal cord stimulation may be tried in refractory instances.

  • What is the root value of femoral nerve?

    The variations in origin of femoral nerve from lumbar plexus is very much common. The normal root value of origin of femoral nerve is L2, L3 and L4. It can be prefixed or postfixed. Mostly the femoral nerve is used for the nerve block in several surgeries and is vulnerable to compression in tight ilio-psoascompartment.

    What is the role of femoral nerve block in pain management?

    A femoral nerve block for post-op pain management works by disrupting pain signals to the brain. It allows patients to begin the path to recovery by helping them become mobile after surgery without significant pain. As a diagnostic tool, femoral nerve blocks also offer insight into what the cause of knee pain might be.

    What is the lateral femoral cutaneous nerve?

    The lateral cutaneous nerve of the thigh (also called the lateral femoral cutaneous nerve) is a cutaneous nerve that innervates the skin on the lateral part of the thigh.
