Stomach Muscle (Abdominal) Strain. Pulled stomach muscle is also called as abdominal muscle strain. This occurs when there is overstretching in one of the abdominal muscles such as the rectus abdominis, internal and external oblique. Most abdominal strains affect the rectus abdominis muscle; the muscle that runs down from the ribs to the pelvis in the middle of the abdomen. Abdominal strain can immediately cause pain to the area of the injured muscle.
3 Types of Muscle Tissue: The Function of Skeletal, Cardiac, and Smooth Muscle. About half of your bodyâs weight is muscle. In the muscular system, muscle tissue is categorized into three distinct types: skeletal, cardiac, and smooth. Each type of muscle tissue in the human body has a unique structure and a specific role. Skeletal muscle moves bones and other structures. Cardiac muscle contracts the heart to pump blood. The smooth muscle tissue that forms organs like the stomach and bladder changes shape to facilitate bodily functions. Here are more details about the structure and function of each type of muscle tissue in the human muscular system.
