In pregnancies that experience rapid fetus growth or women with particularly weak abdominal muscles, this pressure can sometimes causes the rectus abdominis muscle to separate along the linea alba, creating a split between the left and right sides of the rectus abdominis.

To measure the amount of electrical activity _ and thus the force of muscular contraction _ researchers placed electrodes on each subject's three largest abdominal muscle groups _ the rectus abdominis, internal obliques and external obliques _ and on one hip flexor muscle.

They have the same arrangement as the upper ones as far as the anterior ends of the intercostal spaces, where they pass behind the costal cartilages, and between the Obliquus internus and Transversus abdominis, to the sheath of the Rectus abdominis, which they perforate.

He has contributed a number of articles to the anatomic descriptions, clinical applications, and aesthetic refinements of the transverse rectus abdominis myocutaneous ( TRAM ) and latissimus flap procedures for breast reconstruction, and is an authority on silicone breast implants and ultrasonic liposuction technologies.

A direct inguinal hernia protrudes through a weakened area in the transversalis fascia near the medial inguinal fossa within an anatomic region known as the inguinal or Hesselbach's triangle, an area defined by the edge of the rectus abdominis muscle, the inguinal ligament and the inferior epigastric artery.

It curves forward in the subperitoneal tissue, and then ascends obliquely along the medial margin of the abdominal inguinal ring; continuing its course upward, it pierces the transversalis fascia, and, passing in front of the linea semicircularis, ascends between the Rectus abdominis and the posterior lamella of its sheath.

Electrophysiological experiments done by Spivak et al . ( 1980 ) on frogs showed that anatoxin-a is a potent agonist of the muscle-type ?12??? nAChR . Anatoxin-a induced depolarizing neuromuscular blockade, contracture of the frog's rectus abdominis muscle, depolarization of the frog sartorius muscle, desensitization, and alteration of the action potential.

Throughout the rest of its extent the aponeurosis passes horizontally to the middle line, and is inserted into the linea alba; its upper three-fourths lie behind the rectus muscle and blend with the posterior lamella of the aponeurosis of the internal oblique; its lower fourth is in front of the rectus abdominis.

Then there are experts like Dr . Richard M . Bachrach, an osteopathic physician and medical director for the Center for Sports and Osteopathic Medicine in Manhattan, who advise forgoing crunch-type movements altogether because they only activate the upper fibers of the rectus abdominis, the wide, flat sheet of muscle that runs the vertical length of the torso, while the rest of the muscle goes unused.
