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.
Basic Muscle Physiology. There are three types of muscle in the human body: Skeletal muscle, cardiac muscle and smooth muscle. The physics of movement in the body only concerns skeletal muscle. A skeletal muscle consists of many muscle fibers, each of which are muscles in their own right.asic Muscle Physiology.
