The gluteal line is a ridge on the femur bone where the gluteus maximus muscle attaches. Phonetically, the word is pronounced as ɡluːtiəl laɪn. The first two letters, "glu," indicate that the word is related to the gluteus muscles. The final syllable, "eal," is pronounced as "ee-ul," and it relates to a line, and the last two letters, "line," mean the ridge or line on the bone. Therefore, the spelling of "gluteal line" accurately reflects the pronunciation and the meaning of the term.
The gluteal line refers to a bony ridge or crest located on the posterior surface of the ilium, one of the three bones that make up the human hip bone. It runs horizontally from the posterior superior iliac spine (the top of the ilium) towards the iliac tuberosity (a roughened protuberance on the outer surface of the ilium). The gluteal line divides the ilium into two distinct regions: the upper greater pelvis and the lower lesser pelvis.
This anatomical feature provides attachment points for several important muscles involved in the movement of the hip and thigh. Specifically, it serves as the attachment site for the gluteus maximus, the largest and most superficial muscle of the buttocks, as well as the tensor fasciae latae, a muscle that helps to stabilize the hip joint and move the thigh. Moreover, the gluteal line serves as a partial origin for the posterior and inferior fibers of the gluteus medius, another muscle that assists in hip abduction and stabilization.
Understanding the gluteal line is essential in the fields of anatomy, physiotherapy, and sports medicine, as it provides a basis for understanding the biomechanics and functional aspects of the hip joint and its associated musculature.

The word "gluteal" comes from the Latin word "gluteus", which means "buttock". It is derived from the Greek word "gloutos", which also means "buttock". The word "line" refers to a mark, point, or crease. Therefore, the etymology of "gluteal line" is the combination of "gluteus" and "line", which refers to a line or mark related to the buttock or buttock muscles.
