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.
A rectus sheath hematoma is an accumulation of blood in the sheath of the rectus abdominis muscle.It causes abdominal pain with or without a mass.. The hematoma may be caused by either rupture of the epigastric artery or by a muscular tear.
Your core is an interconnected group of muscles that includes all your abs — not just your rectus abdominis, the long vertical muscle that can appear as a visible six-pack in people with low ...
The aponeurosis of the abdominal external oblique muscle is a thin but strong membranous structure, the fibers of which are directed downward and medially.. It is joined with that of the opposite muscle along the middle line, and covers the whole of the front of the abdomen; above, it is covered by and gives origin to the lower fibers of the pectoralis major; below, its fibers are closely ...
Digital Art by Sofia Kraushaar. Muscles Worked: A plank is a full-body exercise, but specifically, it works your transverse abdominis, rectus abdominis (aka the six-pack), internal and external ...
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.
The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the “sit-up” muscles) that originate at the pubic crest and pubic symphysis, and extend the length of the body’s trunk.
