internal oblique การใช้

• It lies between the internal oblique and the underlying transverse fascia.
• It is a continuation of the aponeurosis of the abdominal internal oblique muscle.
• For this reason, the internal obliques are referred to as " same side rotators ."
• The strain usually occurs due to the internal oblique muscle contracting suddenly from a stretched position.
• In some cases, an internal oblique radiography and radionuclide imaging can add information to anterior-posterior and lateral views.
• The anterior layer is derived from the external oblique aponeurosis and the anterior lamina of the internal oblique aponeurosis.
• Superior to the arcuate line, the internal oblique aponeurosis splits to envelop the rectus abdominis muscle both anteriorly and posteriorly.
• The posterior layer is made up of the posterior lamina of the internal oblique aponeurosis and the transversus abdominis aponeurosis.
• Anatomically, the lateral cremaster muscle originates from the internal oblique muscle, just superior to the inguinal canal, and the middle of the inguinal ligament.
• The internal oblique is a small, thin, deep muscle of the abdomen that extends from the hip bone to the cartilage of the lower ribs.
• This branch ascends between the internal oblique muscle and the transversus abdominis muscle, supplying them, and anastomosing with the lumbar arteries and inferior epigastric artery.
• From there, it travels posteriorly between the transversus abdominis muscle and the internal oblique muscle to anastomose with the iliolumbar artery and the superior gluteal artery.
• Inferior to the arcuate line, the internal oblique and transversus abdominis aponeuroses merge and pass superficial ( i . e . anteriorly ) to the rectus muscle.
• For example, the right internal oblique and the left external oblique contract as the torso flexes and rotates to bring the left shoulder towards the right hip.
• It is formed of longitudinal and transverse fibers that bridge the aponeuroses of internal oblique and costal angles and iliac crest laterally, to the vertebral column and sacrum medially.
• The ilioinguinal nerve then perforates the transversus abdominis near the anterior part of the iliac crest, and communicates with the iliohypogastric nerve between the transversus and the internal oblique muscle.
• It then pierces the posterior aponeurosis of the Transversus abdominis, and, passing forward between this muscle and the Internal Oblique, anastomoses with the superior epigastric, lower intercostal, and lumbar arteries.
• Near the crest of the ilium the iliohypogastric nerve then pierces through the transversus abdominis, and divides between that muscle and the internal oblique muscle into a lateral and an anterior cutaneous branch.
• It then pierces the internal oblique, becomes cutaneous by perforating the aponeurosis of the external oblique about 2.5 cm . above the subcutaneous inguinal ring, and is distributed to the skin of the hypogastric region.
• The distance between the right and left rectus abdominis muscles is created by the stretching of the linea alba, a connective collagen sheath created by the aponeurosis insertions of the transverse abdominis, internal oblique, and external oblique.
