genitofemoral nerve

In modern texts, these two regions are often considered to be innervated by the genitofemoral nerve.

But extension of the standard triple neurectomy to include the genitofemoral nerve has given good results, on a small series of 16 patients.

The genitofemoral nerve is responsible for both the efferent and afferent limbs of the cremasteric reflex.

Genital ramus of genitofemoral nerve.

The cremaster muscle is innervated from the genital branch of the genitofemoral nerve and supplied by the cremasteric artery.

In human anatomy, the genitofemoral nerve (sometimes called the genitocrural) originates from the upper part of the lumbar plexus of spinal nerves.

However, standard triple neurectomy does not address inguinodynia secondary to neuropathy of the genitofemoral nerve and the preperitoneal segment of its genital branch.

The genitofemoral nerve (L1, L2) leaves psoas major below the two former nerves, immediately divides into two branches that descends along the muscle's anterior side.

In the upper part of the thigh the lateral branch of the intermediate cutaneous communicates with the lumboinguinal branch of the genitofemoral nerve.

More specifically, the reflex utilizes sensory and motor fibers of the genitofemoral nerve, formed by fibers from both the L1 and L2 spinal nerves.

When the inner thigh is stroked, sensory fibers of the femoral branch of the genitofemoral nerve and the ilioinguinal nerve are stimulated.

Nerves: nerve to cremaster (genital branch of the genitofemoral nerve), testicular nerves (sympathetic nerves)

Medial to lateral these are the: Rosenmuller lymph node, femoral vein, femoral artery, and femoral branch of genitofemoral nerve.

The genital branch of the genitofemoral nerve, cremasteric artery, and ilioinguinal nerve all run on the superficial surface of the external spermatic fascia.

The genital branch of the genitofemoral nerve (external spermatic nerve) arises from the ventral primary divisions of L1 and L2 spinal nerve roots.

It transmits the great saphenous vein and other smaller vessels (like superficial epigastric artery and superficial external pudendal artery), as well as the femoral branch of the genitofemoral nerve.

The vascular lacuna (Latin: lacuna vasorum) is the medial compartment beneath the inguinal ligament, for the passage to the femoral vessels, lymph node, and femoral branch of the genitofemoral nerve.

It is a triangular opening that forms the exit of the inguinal canal, which houses the ilioinguinal nerve, the genital branch of the genitofemoral nerve, and the spermatic cord (in men) or the round ligament (in women).

These synapse in the spinal cord and activate the motor fibers of the genital branch of the genitofemoral nerve which causes the cremaster muscle to contract and elevate the testis (see diagram for location of these nerve regions and location of stimulating stroke).
