Myotome portion of the somites give rise to most of the skeletal muscles of the body. Muscles of the extremities develop from somatic mesoderm. Splanchnic mesoderm gives rise to cardiac muscle and most of the smooth muscles; whereas mesoderm of the pharyngeal arches gives rise to some of the head and neck muscles. The sternalis muscle is a derivative of superficial part of the rectus abdominis ...

One cause of groin pain in highly active patients may be a core muscle injury, commonly referred to as sports hernia. When patients fail nonoperative management, there are a number of surgical options that may be pursued. Typically, they will involve the direct repair of the rectus abdominis back to the pubis. However, we believe that this repair can be further strengthened by the appropriate l...

The Obliquus abdominis externus profundus was found to be present in eleven cases among 50 sides examined in Japanese adult cadavers (frequency of occurrence 22%). This muscle originated at a level ranging from the fifth to seventh rib either by a single slip from one of these ribs (nine cases) or by two slips from two ribs (two cases), and ran medialwards almost horizontally to insert into the...

OBJECTIVE To report 10 cases of rectus abdominis endometrioma, emphasizing the clinical presentations, imaging investigations, cytohistological findings, and surgical treatment employed. METHODS This is a descriptive analysis of 10 surgically-proven cases of rectus abdominis muscle endometriosis, seen over a 5-year period from 2007 to 2012 at Sohag University Hospital, Sohag, Egypt and Najran...

Previous studies investigated the effects of load carriage on electromyographic (EMG) response of three selected trunk muscles of children aged between nine and ten during treadmill walking. (Hong and Cheung, 2002). In this study, similar experimental setup was used to investigate the muscle activities during prolonged load carrying walking on younger children aged six. One more muscle, the rec...

PURPOSE The aim of the present study was to assess, in cadavers, the resistance to medial traction of the posterior and anterior layer of the rectus abdominis muscle sheath. METHODS An anatomical, prospective, self-controlled study was carried out in 20 male cadavers. An evaluation of the tension of the posterior and anterior layers of the rectus abdominis muscle sheath was performed followin...

In human diseases, skeletal muscle regeneration is a powerful, naturally-occurring process of tissue reconstruction that follows upon myofiber damage secondary to injury, which does not affect the tissue circulation and scaffold. On the other hand, the ablated tissue, in traumatology and free muscle grafting, is commonly seen to be replaced by scars. The final outcome is poor even after in situ...
