What is transversus abdominis?

transversus abdominis, also known as transverse abdominis, is the deepest of the four muscles together as the abdomen. This muscle, which wrapped up the intermediaries as a corset, is not visible as the "six packs" of the abdominal muscle rectus, nor well known. However, it is necessary to maintain an upright posture and for proper breathing, and is therefore important for the function of the core.

Found under rectus abdomen, outer oblique and internal oblique, or, the transversus of the abdomen is wide and flat with fibers that are horizontally running. The abdominal abdomen from the ribbon to the hip bones, the highest fibers of this muscle come from ribs, intermediate fibers on the sides of the abdomen and the highest fibers on the hip bones. Specifically, Transversus of the abdomen will find its origin along the class, which leads diagonally across the side of the hair up and out to the front superior Iliac spine on the upper front of the hip. It also comes from the inside of the iliakal ridge, the bone meaning felt on the front of the hip, from the inside of the lower six ribsAnd from the lumbodorsal fascia, the connective tissue packed the waist sides.

Fibers of this muscle insert along a wide layer of connective tissue running down in the middle of the abdomen known as aponeurosis. From the thoracic bone or breast bone in the chest to the hair, the aponeurosis on both sides of the linea album, the middle line of the abdominal substances that is visible in the "six package". Its fibers also run horizontally, bounded by media or inward, linea album and laterally, or exterior, transversus fibers of the abdomen.

Unlike rectus abdominis and oblique, the task of which is to move the torso of either flexion, bending forward or hip, or podlerotation or twisting, transversus abdominis is responsible for compression and stabilization. Compression is caused by muscle drawing inside, exerting pressure on ribs and internal organs, as a means of stabilizing the nucleus and pelvic areas. Simply put, it helps to reduce pressure down on FriTeř and stress on the lower back, especially during heavy lifting movements, and also helps maintain erect posture. The action of this muscle also helps pregnant women in pushing during work and childbirth.

Another important effect of transversus abdominis is its role in breathing. The membrane, the muscle muscle in the shape of an umbrella filling the lower part of the rib cage under the lungs allows inhalation. When it is withdrawn, it reduces the pressure on the thoracic cavity and allows the lungs to expand and stretch the air. On the other hand, abdominal, especially transversus of the abdomen, helps in exhale by exerting pressure on the thoracic cavity, which is against the activated membrane with every breath. This relationship of contradictory actions between the two muscle groups is known in anatomy as antagonistic.
