The spelling of "nervus ilioinguinalis" may seem confusing due to its Latin origin. However, it can be broken down phonetically using IPA transcription as "ˈnɛrvəs ˌɪliˌoʊˈɪŋgwɪnəlɪs". This refers to a nerve that runs from the lower abdomen to the thigh area. Understanding the spelling of medical terms can be helpful in accurately communicating with healthcare professionals and accessing information about medical conditions. It is therefore important to familiarize oneself with commonly used medical terminology.
The nervus ilioinguinalis, also known as the ilioinguinal nerve, is a sensory nerve in the human body that originates from the first lumbar nerve (L1) of the spinal cord. It is named based on its anatomical position, originating from the lumbar plexus region and traversing through the ilioinguinal canal.
The nervus ilioinguinalis runs along the anterior abdominal wall, in close proximity to other nerves such as the nervus iliohypogastricus and the genitofemoral nerve. It provides sensory innervation to specific areas of the lower abdomen, the inguinal region, and the upper portion of the genitalia including the mons pubis, pubic symphysis, and anterior scrotum or labia majora.
Functionally, the nervus ilioinguinalis plays a role in transmitting sensory information, primarily detecting pain, temperature, and touch, from the designated areas it innervates. It is particularly important for transmitting sensory signals from the skin of the lower abdomen, enabling an individual to perceive and respond to external stimuli affecting this region.
Clinically, the nervus ilioinguinalis can be involved in certain medical conditions such as ilioinguinal neuralgia, which is characterized by chronic pain in the distribution of the nerve. Additionally, surgical procedures in the lower abdomen or inguinal area may impact the integrity of the nerve, potentially leading to temporary or permanent sensory disturbances in the innervated region.
Ilioinguinal nerve, arises from the first lumbar, passing through the psoas, forward in the abdominal wall, and then through the external abdominal ring when it becomes superficial; it supplies the muscles of the abdominal wall and the skin of the mons Veneris or, in the male, root of the penis.

The term nervus ilioinguinalis has Latin origins.
- Nervus in Latin means nerve.
- Ilium refers to the upper part of the hip bone.
- Inguinalis pertains to the groin area, which is the region between the lower abdomen and the upper thigh.
Therefore, the term nervus ilioinguinalis can be translated as the nerve of the upper hip/groin region.
