The term "musculus iliacus minor" refers to a small muscle located in the iliac fossa, which is a region of the pelvic bone. Although this muscle is not widely recognized by alternative names, it has been referred to in medical literature as "iliacus pars peculiaris" or simply "minor iliacus". These synonyms basically describe the same muscle, emphasizing its relative size and its association with the iliac bone. Despite its size, the musculus iliacus minor plays an important role in the movement and stability of the hip joint, aiding in flexion and assisting other larger muscles in maintaining proper alignment and function.
