The Abdomen 1 There are four important paired muscles in the anterior abdominal wall: three flat muscles (external oblique, internal oblique, and transversus abdominis) and one strap-like muscle (rectus abdominis).osterior Abdominal Wall. 1  The posterior abdominal wall is composed principally of muscles and fascia attached to the vertebrae, hip bones, and ribs. 2  It also contains fat, important nerves, vessels, and lymph nodes.

The gluteal muscles The gluteus maximus is the uppermost of the three muscles. It is the largest of the gluteal muscles and one of the strongest muscles in the human body (see Muscle). It inserts at the iliotibial band and the gluteal tuberosity of the femur.

- An anatomical illustration showing many muscles in the upper body, including the external abdominal oblique muscle (or obliquus externus abdominis). Having strong obliques may help support a strong back. Obliques are the stomach muscles located toward the sides of the body.n the front of the abdomen, there is a major muscle called the rectus abdominis, which stretches from pubis to the ribs. On either side of the rectus abdominis, right at the hips, the internal obliques are located.

Anterior Abdominal Muscles Function. The main tasks of the rectus abdominis muscle and the lateral abdominal muscles are the movement of the trunk, stabilization of the vertebral column and the tensioning of the abdominal wall.They are responsible for the abdominal press increasing the intra-abdominal pressure (e.g. during defecation or vomiting).n particular, the rectus abdominis muscle does a ventral flexion (flexion of the trunk or erection of the pelvis) and thus is an important antagonist of the intrinsic back muscles.

The Anterolateral Abdominal Wall These muscles act to flex, laterally flex and rotate the trunk. Their fibres run in differing directions and cross each other – strengthening the abdominal wall and decreasing the risk of herniation. External Oblique. The largest and most superficial flat muscle in the abdominal wall.Its fibres run inferomedially. As the fibres approach the mid-line, they form an aponeurosis (a broad flat tendon). In the mid-line, the aponeuroses of all the flat muscles become entwined, forming the linea alba.hese muscles act to flex, laterally flex and rotate the trunk. Their fibres run in differing directions and cross each other – strengthening the abdominal wall and decreasing the risk of herniation. External Oblique. The largest and most superficial flat muscle in the abdominal wall.

Muscles of the Trunk - Townsville Massage Transversus Abdominus. Of the four muscles of the abdominal muscle group, the Transverse Abdominis is the one that does not cause trunk movement. When you “suck it in,” it’s muscle that pulls the ab wall in. It is located deep in your abdomen, underneath your obliques. It holds your organs in place and forces expiration when contracted.

Muscles In Depth: Muscles. The rectus abdominis is the large muscle in the mid-section of the abdomen. It enables the tilt of the pelvis and the curvature of the lower spine.Next to it on both sides of the body is the internal oblique.t stretches from the front of the abdomen to the back of the torso. The external oblique muscles run diagonally down and in from the lower ribs to the pelvis. They allow you to bend sideways and rotate your torso. Another important group of muscles related to posture is the erector spinae.

ABDOMINAL MUSCLES ANATOMY These muscles resemble sheets of muscle tissue, flat and in some cases even straight during contraction. The external abdominal oblique, the internal abdominal oblique, transversus abdominis, and the rectus abdominis are the muscles which create the abdominal wall.he deepest of the muscles of the abdomen is the transversus abdominis. The long fibers of this muscle are put to use across the abdominal wall, laterally. A large sheath encases the long rectus abdominis in its entirety.

External Abdominal Oblique Muscle The external abdominal obliques are a pair of broad, thin, superficial muscles that lie on the lateral sides of the abdominal region of the body. Contraction of these muscles may result in several different actions, but they are best known for their lateral flexion and rotation of the trunk known as a side bend.he external obliques get their name from their position in the abdomen external to the internal abdominal obliques and from the direction of their fibers, which run obliquely (diagonally) across the sides of the abdomen....

The Lateral Abdominal Muscles 1 Abdominal external oblique muscle (left): courses from the 5th to 12th rib ventromedially to the anterior layer of the rectus sheath. 2  At its origin it is tightly connected with the serratus anterior and latissimus dorsi muscle.n the long term this threatens a hyperlordosis of the lumbar vertebral column. An insufficiency of the lateral abdominal muscles and their aponeuroses (e.g. in obese people or physiologically during pregnancy) may cause a diastasis recti where the rectus sheaths spread apart from the linea alba.

muscle Muscles of the Abdominal Wall. There are five muscles in the abdominal wall. They can be divided into two groups: Vertical muscles – There are two vertical muscles, situated near the mid-line of the body. Flat muscles – There are three flat muscles, situated laterally.

Chest Wall Anatomy The external oblique muscle is the largest and thickest of the flat abdominal wall muscles. It originates from the lower 8 ribs, interlocks with slips of latissimus dorsi and serratus anterior, and courses inferior-medially, attaching via its aponeurosis centrally at the linea alba.inea alba. The linea alba is the fusion of the anterior and posterior rectus fascia; it is located in the abdominal midline, between the rectus muscles, from the xiphoid to the pubis. The linea alba is a 3-dimensional composition of tendon fibers from abdominal wall muscles.

Internal oblique The internal abdominal oblique muscle is an opposing force to the diaphragm, reducing upper chest cavity volume during exhalation. As the diaphragm contracts, the chest cavity is pulled down to increase lung size.he internal abdominal oblique muscle is located closer to the skin than the transverse abdominal muscle.

- These muscles form a basket which encloses the viscera. Contraction of the abdominal muscles serves to compress the abdomen. The external oblique forms the most superficial of the three layers of abdominal muscles. This muscle originates from the posterior ribs and the lumbodorsal fascia.The fibers extend craniodorsally to insert along the length of the linea alba.. Linea alba. This image shows a ventral view of the abdominal wall of a cat, with the external oblique muscle reflected laterally. The abdominal wall consists of three sheet-like layers of muscle along with a band-like, longitudinal muscle located along the midventral line (linea alba).

ABDOMINAL MUSCLES ANATOMY Choosing from the three layered muscles of the lateral abdominal wall, the external abdominal oblique remains the most superficial yet ironically the strongest. The fibers of the muscle are directed medially and inferiorly to amplify its contraction.he deepest of the muscles of the abdomen is the transversus abdominis. The long fibers of this muscle are put to use across the abdominal wall, laterally. A large sheath encases the long rectus abdominis in its entirety.

It is broad, thin, and irregularly quadrilateral, its muscular portion occupying the side, its aponeurosis the anterior wall of the abdomen.he muscle is inserted by three portions of unequal size into the cartilages of the fifth, sixth, and seventh ribs. The upper portion, attached principally to the cartilage of the fifth rib, usually has some fibers of insertion into the anterior extremity of the rib itself.

Internal oblique The internal abdominal oblique muscle ends at the bottom edge of the rib cage, the rectus sheath (fibrous tissue that covers the abdominal muscles), and the pubic crest (an area in the lower-front of the pelvis). The internal abdominal oblique muscle is located closer to the skin than the transverse abdominal muscle.This muscle supports the abdominal wall, assists in forced respiration, aids in raising pressure in the abdominal area, and rotates and turns the trunk with help from other muscles.nternal abdominal oblique muscles are called “same side rotators.” The right internal oblique works with the left external oblique, and vice versa, when flexing and rotating the torso.
