<em>Study design and data collection</em> Thirty-one adult cadavers of both sexes (26 males and five females) were utilized from the Department of Anatomy at KMC, Manipal for morphometric measurements. With the surgical instruments, cadavers were dissected and muscles were exposed. The following parameters were measured using a vernier calliper. Length of muscle from the pubic symphysis to its attachment to linea alba (apex) along its medial border. Width at the base/origin of the muscle. The thickness of the muscle at the midpoint of the measured length. Distance between the umbilicus and pubic symphysis (DUP) and distance between the umbilicus and apex of the muscle (DUA). Distance between the anterior superior iliac spine (ASIS) and lateral part of the base of the muscle (LBM). Distance between ASIS to tip of the muscle. Distance between ASIS and the pubic symphysis (ASIS-PS). The length and breadth of the gap found between the right and left PM at the base were measured in cadavers where the gap was seen.
