Definition
The anterior labial nerves are branches of the ilioinguinal nerve, which originates from the anterior ramus of the L1 spinal nerve. These nerves specifically provide sensory innervation to the anterior regions of the mons pubis and the labium majus, parts of the external genitalia in females. They branch off the ilioinguinal nerve after it passes through the inguinal canal and exits via the superficial inguinal ring.
In males, the analogous structures are the anterior scrotal nerves.
