A muscle strain occurs when the muscle is stretched too far. When this occurs the muscle fibers are torn. Most commonly, a strain causes microscopic tears within the muscle, but occasionally, in severe injuries, the muscle can rupture from its attachment. A rectus sheath hematoma is an accumulation of blood in the sheath of the rectus abdominis ...
The rectus abdominis muscle is crossed by three fibrous bands called the tendinous intersections or tendinous inscriptions.One is usually situated at the level of the umbilicus, one at the extremity of the xiphoid process, and the third about midway between the two.

It is a hyaline degeneration of skeletal muscles such as rectus abdominis and diaphragm, and occurs in severe toxaemia as typhoid fever. It is also seen in electrical burns. [1] Grossly the muscles appear pale and friable; microscopically, the muscle fibres are swollen, have a loss of cross striations, and show a hyaline appearance.
