The transversalis fascia (or transverse fascia) is the fascial lining of the anterolateral abdominal wall [1] [2] situated between the inner surface of the transverse abdominal muscle, and the preperitoneal fascia. [3] [2] It is directly continuous with the iliac fascia, [2] the internal spermatic fascia, [citation needed] and pelvic fascia. [2]
Twelfth rib syndrome, also known as rib tip syndrome, is a painful condition that occurs as a result of highly mobile floating ribs.It commonly presents as pain that may be felt in the lower back or lower abdominal region as a result of the 11th or 12th mobile rib irritating the surrounding tissues and nervous systems.
Muscle [3] Visual reference Method of activation 1: Anterior and middle scalenes: Look straight ahead and lift head anterior 2: Posterior scalenes: Turn head 30 degrees away and lift anterior 3-5: Pectoralis minor: Push ipsilateral elbow towards opposite ASIS. 6-8: Serratus Anterior: Push arm anteriorly 9-11: Latissimus dorsi
Abdominal muscles cover the anterior and lateral abdominal region and meet at the anterior midline. These muscles of the anterolateral abdominal wall can be divided into four groups: the external obliques , the internal obliques , the transversus abdominis , and the rectus abdominis .
The anterior cutaneous branch ("hypogastric branch") continues onward between the abdominal internal oblique and transverse muscles.. 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 renal capsule surrounds the functional tissue of the kidney, and is itself surrounded by a fatty adipose capsule, fascia, and fat. From the inner part of the kidney to outside the kidney, the positioning of the capsule is: renal medulla; renal cortex; renal capsule; adipose capsule of kidney (or perirenal fat, or perinephric fat) renal fascia
Anterior to the quadratus lumborum are the colon, the kidney, the psoas major muscle, (if present) the psoas minor muscle, and the diaphragm; between the fascia and the muscle are the twelfth thoracic, ilioinguinal, and iliohypogastric nerves. The quadratus lumborum muscle is a continuation of transverse abdominal muscle.
The posterior layer is made up of the posterior lamina of the internal oblique aponeurosis and the transversus abdominis aponeurosis. [1] Inferior to the arcuate line, the aponeuroses of the external oblique muscle, the internal oblique muscle, and the transversus abdominis muscle merge and pass superficial to the rectus abdominis muscle.
