Definition
The gluteal surface of ilium refers to its outer or external surface of. It is bounded above by the iliac crest and limited below by the acetabulum. This surface is characterized by three distinct gluteal lines: From anterior to posterior, these include the inferior, anterior, and posterior gluteal lines. Between these lines, three important gluteal muscles, namely the gluteus maximus, medius, and minimus, have their origins on the gluteal surface of ilium.
The gluteus maximus originates behind the posterior gluteal line.
The gluteus medius fibers originate between the posterior and anterior gluteal lines.
The gluteus minimus originates between the anterior and inferior gluteal lines.
The reflected head of the rectus femoris muscle, an anterior thigh muscle, originates just above the acetabulum beneath the inferior gluteal line.
