What muscles does the lateral femoral cutaneous nerve innervate?
psoas major muscle.
What is the function of the lateral cutaneous nerve of the thigh?
Function. The lateral cutaneous nerve of the thigh is a sensory nerve. It supplies the skin on the lateral (outer) part of the thigh.
What is the lateral femoral cutaneous nerve?
The lateral femoral cutaneous nerve is usually derived from the dorsal branches of the L2 and L3 ventral rami. It appears from under the lateral border of the psoas major and travels towards the notch on the anterior superior iliac spine (ASIS), exiting the lesser pelvis by passing under the inguinal ligament.
How do you release the lateral femoral cutaneous nerve?
Procedure for Lateral Femoral Cutaneous Nerve Decompression An incision is made in a lateral fashion on the affected side using loupe magnification (a device used to see small details more closely). The underlying muscles are carefully separated to expose the lateral femoral cutaneous nerve in the upper thigh area.
How do you test the lateral femoral cutaneous nerve?
Rarely, doctors order a nerve conduction study. This test evaluates how well your lateral femoral cutaneous nerve sends electrical impulses to the surrounding muscles. To measure electrical impulses, your doctor places electrodes along the LFCN. These electrodes measure how fast the LFCN transmits impulses.
What is the lateral cutaneus femoris lateralis?
nervus cutaneus femoris lateralis. TA98. A14.2.07.011. TA2. 6521. FMA. 16485. Anatomical terms of neuroanatomy. 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 .
Where does the lateral femoral cutaneous nerve exit the spine?
The lateral femoral cutaneous nerve is a branch of the lumbar plexus, exiting the spinal cord between the L2 and L3 vertebrae. It emerges at the lateral edge of the psoas muscle group, below the ilioinguinal nerve, and then passes beneath the iliac fascia and the inguinal ligament.
What is the lateral cutaneous nerve of the thigh?
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. Plan of lumbar plexus. (Lateral femoral cutaneous visible at left.) Cutaneous nerves of the right lower extremity. Front and posterior views.
What are the symptoms of lateral femoral cutaneous nerve damage?
Lateral femoral cutaneous nerve. Neuropathies (nerve damage) of the lateral femoral cutaneous nerve can arise from many different clinical situations, and often manifest as sensory loss or pain, which can be tingling, aching, or burning. Common causes of this condition, known as meralgia paresthetica, include tight clothing, obesity, pregnancy,…
