The somatic nerves of the pelvis include the Lateral Femoral Cutaneous nerve, Femoral nerve, Genitofemoral nerve, Obturator nerve and the Lumbosacral trunk.
What type of nerve is the genitofemoral nerve?
The genitofemoral nerve is a branch of the lumbar plexus arising within the substance of the psoas major muscle from the union of anterior rami of L1 and L2 spinal nerves.
Does the genitofemoral nerve go through the superficial inguinal ring?
It emerges from the lateral border of the psoas and courses along the abdomen along the iliac crest; it then pierces the transversus abdominus near the anterior superior iliac spine (ASIS) and enters the inguinal canal and passes through the superficial inguinal ring, accompanying the spermatic cord in males or the …
What muscles are innervated by the genitofemoral nerve?
The genitofemoral nerve (also genitocrural nerve, latin: nervus genitofemoralis) is a mixed nerve that originates from the lumbar plexus and innervates the upper, anterior thigh, and skin of the anterior scrotum in males or labia majora in females.
What does the genitofemoral nerve supply?
The genitofemoral nerve supplies sensation via the femoral branch and motor innervation via the genital branch. The cremasteric reflex is a function of genitofemoral nerve innervation, as it supplies sensation to the superior medial aspect of the thigh.
What is Genitofemoral neuralgia?
Genitofemoral neuralgia is a syndrome characterized by chronic pain and paresthesia in the region of genitofemoral nerve distribution. Genitofemoral nerve entrapment has been described after inguinal herniorrhaphy, appendectomy, and cesarean section.
How do you know if you have a genitofemoral nerve?
The genitofemoral nerve is formed from the first and second ventral rami of the lumbar nerve within the substances of the psoas major. It emerges on the anterior surface of psoas major along the medial border. It then descends on psoas major within the fascia iliaca and crosses posterior to the ureter and peritoneum.
Is genitofemoral nerve in spermatic cord?
The genital branch of the genitofemoral nerve arises from the ventral primary divisions of L1-L2 spinal nerve roots. It passes outward on the psoas major muscle, and pierces the fascia transversalis, or passes through the deep inguinal ring. It then descends within the spermatic cord.
What does femoral nerve pain feel like?
Symptoms may include any of the following: Sensation changes in the thigh, knee, or leg, such as decreased sensation, numbness, tingling, burning, or pain. Weakness of the knee or leg, including difficulty going up and down stairs — especially down, with a feeling of the knee giving way or buckling.
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. 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 is the perineal nerve?
The perineal nerve is the largest and most inferior of the three branches of the pudendal nerve (the other branches being the inferior rectal nerve and the dorsal nerve of the penis or clitoris). The nerve originates in the pudendal canal, which is formed by the fascia of the obturator internus muscle.
What happens when the Genitofemoral nerve is damaged?
It is characterized by chronic neuropathic groin pain that is localized along the distribution of the genitofemoral nerve. The symptoms include groin pain, paresthesias, and burning sensation spreading from the lower abdomen to the medial aspect of the thigh.
Where 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.
What is Subcostal nerve?
Subcostal nerve (T12). The subcostal nerve provides sensory innervation to the region under the umbilicus and also provides motor innervation to the pyramidalis and quadratus lumborum muscles. … This nerve provides motor innervation to the muscles of the anterior abdominal wall.
How do you treat Genitofemoral nerve?
- Medications, such as anticonvulsants.
- Nerve blocks.
- Steroid Injections.
- Surgical intervention: Surgery can sometimes be helpful, but can also sometimes provoke the pain.
What is Hesselbach’s triangle?
Hesselbach’s triangle or the inguinal triangle is a triangular area on the inferior interior aspect of the anterior abdominal wall within the groin.
How do you stop inguinal nerve pain?
tricyclic antidepressants to help reduce pain. antiseizure medications like pregabalin (Lyrica) or gabapentin (Neurontin) to reduce the painful effects of a pinched nerve. physical therapy to help you learn how to move your groin, hip, or leg muscles so that you don’t pinch or damage nerves.
What is the signs of nerve damage?
The signs of nerve damage

- Feeling like you’re wearing a tight glove or sock.
- Muscle weakness, especially in your arms or legs.
- Regularly dropping objects that you’re holding.
- Sharp pains in your hands, arms, legs, or feet.

How can I sleep with femoral nerve pain?
The best option is to sleep on the side opposite the discomfort with a pillow between your legs. (If the burning is in your left thigh, sleep on your right side.) This can help ease the compression of the nerve enough to allow you to get to sleep.
What nerve runs through groin?
The lateral femoral cutaneous nerve, which runs through the pelvis, groin and into the thighs, can become compressed due to swelling, trauma or pressure in the surrounding areas. Common causes of meralgia paresthetica may include: Repetitive motion of the legs.
What nerve passes through the groin?
The ilioinguinal nerve is a branch of L1. It passes through the deep inguinal orifice along with the cord structures.
What nerves are in the groin?
Nerves of the Groin Region:
- the iliohypogastric nerve.
- the ilioinguinal nerve.
- the obturator nerve.
- the anterior femoral cutaneous nerve (a branch of the femoral nerve)
What is ilioinguinal nerve entrapment?
The ilioinguinal nerve entrapment syndrome is an abdominal muscular pain syndrome, characterized by the clinical triad of muscular type iliac fossa pain with a characteristic radiation pattern, an altered sensory perception in the ilioinguinal nerve cutaneous innervation area, and a well-circumscribed trigger point …
