muscle Muscles of the Abdominal Wall. Your abdominal wall is composed of a complex of six muscles: the rectus abodminis, the internal and external obliques, the transversus abdominis, the pyramidalis and the cremaster.The pyramidalis and cremaster are located deep in the pelvic floor and do not contribute to movement.he linea alba is a tendinous sheath that attaches the right and left sides of the muscle and three tendinous attachments divide the muscle into six segments that create the six-pack. The rectus abdominis functions to flex the trunk, shortening the distance between the ribs and the pelvis.

External Abdominal Oblique Muscle 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.

Chapter 25: Abdominal walls The aponeurosis of the external oblique muscle passes anterior to the rectus abdominis. Its inferior edge extends from the anterior superior iliac spine to the pubic tubercle and is known as the inguinal ligament. A part that continues posterior (toward the superior pubic ramus) is termed the lacunar ligament.nteriorly, the abdominal wall includes the rectus abdominis muscles, and the aponeuroses of the three muscles (the external and internal oblique and the transversus) that form much of the side of the abdomen. Posteriorly, the lumbar vertebrae and intervertebral discs project anteriorward (fig. 25-2).

- 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 The deepest layer of abdominal muscles is called the transversus abdominis.. The transverse abdominal muscle wraps around the torso from front to back and from the ribs to the pelvis. The muscle fibers of the transversus abdominis run horizontally, similar to a corset or a weight belt. This muscle doesn't help move the spine or the pelvis, but it does help with respiration and breathing.

Introduction The abdominal muscles form the anterior and lateral abdominal wall and consist of the external abdominal obliques, the internal abdominal obliques, the rectus abdominis and the transversus abdominis .

76 11.4 Axial Muscles of the Abdominal Wall, and Thorax Figure 1. Muscles of the Abdomen. (a) The anterior abdominal muscles include the medially located rectus abdominis, which is covered by a sheet of connective tissue called the rectus sheath. On the flanks of the body, medial to the rectus abdominis, the abdominal wall is composed of three layers.

Chapter 25: Abdominal walls Anteriorly, the abdominal wall includes the rectus abdominis muscles, and the aponeuroses of the three muscles (the external and internal oblique and the transversus) that form much of the side of the abdomen.5-3, 25-4, 25-5, 25-6 and 25-7). The anterior part of the abdominal wall contains the rectus abdominis and pyramidalis muscles. The external and internal oblique muscles and the transversus abdominis muscle are lateral (table 25-1). The fibers of the rectus run vertically.

- In short, the tip of your bladder. Right behind your umbilicus is the rectus sheath of connective tissue which connect the muscles of the anterior abdominal wall. This forms the linea alba -- the middle vertical line in the abdominal muscles. Beneath that is the transversalis fascia, another layer of connective tissue, and then the peritoneum.

Gluteal muscles The gluteus maximus is the largest and most superficial of the three gluteal muscles. It makes up a large portion of the shape and appearance of the hips. It is a narrow and thick fleshy mass of a quadrilateral shape, and forms the prominence of the nates.

Fasciae and Ligaments of the Abdominal Wall Superficial fasciae. Overlying the muscular layers of the abdominal wall are two layers of fatty tissue, forming the subcutaneous tissue. These subcutaneous tissues make up the superficial fascia of the abdominal wall, but change their names at the level of the umbilicus to Camper’s fascia (superficially) and Scarpa’s fascia.

- The Pfannenstiel incision transects neurovascular pathways in the skin of the abdominal wall and frequently requires partial or compete transection of the rectus abominis muscle. It is rarely associated with incisional hernia, has a low incidence of wound dehiscence, and heals without significant scarring.

- The external oblique muscle is one of the largest parts of the trunk area. Each side of the body has an external oblique muscle. The external oblique muscle is one of the outermost abdominal muscles, extending from the lower half of the ribs around and down to the pelvis.

The Intrinsic Back Muscles The superficial muscles are also known as the spinotransversales. There are two muscles in this group – splenius capitis and splenius cervicis. They are both associated with movements of the head and neck. They are located on the posterolateral aspect of the neck, covering the deeper neck muscles. Splenius Capitis

Training for the deep muscles of the core Transversus abdominis is the deepest of the abdominal muscles and wraps around the abdomen between the lower ribs and top of the pelvis, functioning like a corset.This picture shows the anatomy of this muscle with the outer two abdominal layers (internal and external oblique) removed.he second step is to strengthen or teach it to co-contract with the other muscles of the core, the deep multifidus and the pelvic floor as you breathe. The final step is to co-contract the entire core (connect to the entire core) and use this connection in functional activities.
