Rectus sheath Rectus sheath. The rectus sheath is made up of two parts, known as the posterior sheath and the anterior sheath. These sheaths are made of fibers of the transversus abdominis, internal abdominal oblique (IAO), and external abdominal oblique (EAO), which are muscles of the abdomen.

Tensor Fasciae Latae Anatomy: Origin, Insertion, Action, Innervation Origin: Outer surface of the anterior iliac crest, between the tubercle of the iliac spine. A thick fascia covers the outer surface of the muscle, making it appear to be sandwiched between the layers of fasciae latae. Insertion: By the iliotibial band anterior surface of the lateral condyle of the tibia. Action: Assists with flexion of the thigh at the hip, assists with adduction of the thigh at the hip.

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.

Background Rectus sheath hematoma is an uncommon, but not rare, cause of abdominal pain. In 1999, Klingler et al found an incidence of 1.8% among 1257 patients admitted to the hospital with abdominal pain and undergoing ultrasonography for diagnosis. Anticoagulation is a well-known risk factor.

Rectus femoris muscle The rectus femoris is a weaker hip flexor when the knee is extended because it is already shortened and thus suffers from active insufficiency; the action will recruit more iliacus, psoas major, tensor fasciae latae, and the remaining hip flexors than it will the rectus femoris.

The Fascia Lata Muscular sheath – forms a sheath for the tensor fascia lata muscle. Tensor Fascia Lata (TFL) The tensor fascia lata is a gluteal muscle that acts as a flexor, abductor and internal rotator of the hip. Its nomenclature however, is derived from its additional role in tensing the fascia lata. The muscle originates from the iliac crest, and descends down the superolateral thigh.

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).

Rectus abdominis muscle Rectus abdominis muscle. The rectus abdominis muscle, also known as the abdominals or abs, is a paired muscle running vertically on each side of the anterior wall of the human abdomen, as well as that of some other mammals. There are two parallel muscles, separated by a midline band of connective tissue called the linea alba.

Which are the Deep Core Stability Muscles? The Transversus Abdominis (TA) is the deepest abdominal muscle. It is the  corset muscle  of the spine and pelvis. In the normal situation, TA contracts in anticipation of body motion to guard the spinal joints, ligaments, discs and nerves.he Transversus Abdominis (TA) is the deepest abdominal muscle.

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.

Rectus sheath Rectus sheath. The rectus sheath is formed by the aponeuroses of the transverse abdominal and the external and internal oblique muscles. It contains the rectus abdominis and pyramidalis muscles. It can be divided into anterior and posterior laminae. The arrangement of the layers has important variations at different locations in the body.

Introduction The internal abdominal oblique muscle is also a broad thin muscular sheet that lies deep to the external oblique muscle. It arises from the thoraco-lumbar fascia, the anterior two-thirds of the iliac crest and the lateral two-thirds of the inguinal ligament.bdominal Muscle Anatomy. Search. The external abdominal oblique muscle is the largest and most superficial of the four muscles and lies on the sides and front of the abdomen. It is broad and thin with it's muscular portion occupying the side and it's aponeurosis the anterior wall of the abdomen.

Clinical Chemistry Analyzers Technology Clinical chemistry analyzers run assays on clinical samples such as blood serum, plasma, urine, and cerebrospinal fluid to detect the presence of analytes relating to disease or drugs. Clinical chemistry analyzers are used in a variety of settings, including small clinics, research labs, and high-throughput hospital labs. They are also used at the point-of-care, such as in physicians’ offices and patient bedsides.

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 superficial muscles in the anterior compartment are the flexor carpi ulnaris, palmaris longus, flexor carpi radialis and pronator teres. They all originate from a common tendon, which arises from the medial epicondyle of the humerus.

Muscles in the Posterior Compartment of the Forearm Fig 1.0 – The muscles in the superficial layer of the posterior forearm. The brachioradialis is a paradoxical muscle. Its origin and innervation are characteristic of a extensor muscle, but it is actually a flexor at the elbow.he aconeus is situated medially and superiorly in the extensor compartment of the forearm. It is blended with the fibres of the triceps brachii, and the two muscles can be indistinguishable. 1  Attachments: Originates from the lateral epicondyle, and attaches to the posterior and lateral part of the olecrannon.
