The iliac tuberosity is a collection of bone tissue in the pelvic area. It has the shape of a comma and is located on the inner surface of the pelvic bone. The tuberosity has several names in various medical sources: - iliaca in Latin - means “sacrum” or “ilium”. This anatomical region is also called terminalis ilii - pna - from English “pathology of neoplasms”, namely regional lymphadenopathy in the iliac lymph nodes can also be called an iliac nodule. - bna - from Latin “big knife”, it also has a number of meanings such as “major ilium”, “adductor magnus”, “clavicle”, “thumb”. The same applies to the Latin abbreviation of this anatomical region in human anatomy, jna. It basically has an analogue meaning with the Latin letter "I", and can also be translated as "dolichoid" or "highly convex". This is exactly how the general medical encyclopedia describes tuberosity with reference to the US National Library.
