Common questions

What muscles does the ilioinguinal nerve innervate?

What muscles does the ilioinguinal nerve innervate?

The ilioinguinal nerve innervates the anterior surface of the scrotum or labia majora, root of the penis or mons pubis, and a small portion of the upper antero-medial thigh. It also innervates the internal oblique and transversus abdominis muscles.

What nerve Innervates the suprapubic area?

Function. The iliohypogastric nerve partially supplies the internal oblique muscles. It also provides sensory innervation to the superior gluteal region and part of the suprapubic region.

What does the iliohypogastric nerve do?

The iliohypogastric nerve originates from the first ventral rami in the lumbar plexus. It supplies motor innervation to the transversus abdominis and the internal oblique muscles.

What type of nerve is ilioinguinal nerve?

The ilioinguinal nerve is a mixed nerve and gives off the following motor and sensory branches: Motor branches: Along its course over the posterior abdominal wall, the ilioinguinal nerve gives off motor branches that supply the transversus abdominis and internal oblique muscles.

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 quadrant of the body is the suprapubic area?

The right lower section is the right lower quadrant (RLQ) – also known as the right iliac region. The central lower section is the suprapubic region – sometimes referred to as the hypogastric region.

What is suprapubic abdominal pain?

Suprapubic pain happens in your lower abdomen near where your hips and many important organs, such as your intestines, bladder, and genitals, are located. Suprapubic pain can have a wide variety of causes, so your doctor may need to do tests of your vital functions before diagnosing the underlying cause.

How do you fix ilioinguinal nerve entrapment?

Treatment of iliohypogastric or ilioinguinal nerve entrapment may include local injection of an anesthetic, oral or topical medications, or physical therapy.

What is Ilioinguinal neuralgia?

Ilioinguinal neuralgia is a frequent cause of pain in the lower abdomen and the upper thigh and is commonly caused by entrapment or injury of the nerve after lower abdominal surgeries. The ilioinguinal nerve is responsible for motor innervation of the transverse abdominis and internal oblique muscles.

What happens if iliohypogastric nerve is damaged?

Symptoms of ilioinguinal nerve injury include: Burning or stabbing pain, numbness, or tingling in the lower abdomen and groin. Difficulty extending the back as this movement causes more pain. Difficulty with sitting, standing and walking.

Is the iliohypogastric nerve in the lumbar plexus?

Iliohypogastric nerve (Nervus iliohypogastricus) The iliohypogastric nerve is a mixed branch of the lumbar plexus . It arises as a single trunk along with the ilioinguinal nerve  from the anterior/ventral ramus of the L1 spinal nerve  root.

Where is the iliohypogastric nerve vulnerable to injury?

The ilioinguinal nerve is vulnerable to injury along its course on the anterior abdominal wall. The genitofemoral nerve is vulnerable to injury along its entire course (retroperitoneum, inguinal canal, and ventral thigh region).

Where does the iliohypogastric nerve pierce the kidneys?

It runs behind the kidneys. Near the iliac crest, the iliohypogastric nerve then pierces through the transversus abdominis muscle. It divides into a lateral cutaneous branch and an anterior cutaneous branch between the transversus abdominis muscle and the internal oblique muscle.

Can a hysterectomy damage the iliohypogastric nerve?

Injury can occasionally occur during surgery with an oblique open approach to the appendix . Damage to the iliohypogastric nerve can also occur in transverse incisions of the lower abdomen, during a hysterectomy, for example. A noticeable sensory loss is rare, as the suprapubic skin receives innervation from multiple nerves.
