Stomach The transpyloric plane passes through the pylorus of the stomach, despite it being suspended by the and and being relatively mobile. These planes are the mid-clavicular lines. Vasculature The arises from the at the level of the transpyloric plane and emerges between the head and neck of the pancreas. The length of each kidney is 11 cm. The axis of the spleen extends antero-laterally along the line of the 10th rib and normally reaches no further forward than the mid-axillary line, so that the normal organ lies beneath ribs 9, 10, and 11.
It lies roughly a hand's breadth beneath the or midway between the xiphisternum and the. History The transpyloric plane relates to the three-dimensional mapping of the abdomen founded on more than 10,000 measurements completed on 40 bodies, that surgeon took at the turn of the 20th century. By 2019 Fig 1 — The layers of the anterolateral abdominal wall. The caecum lies in the right iliac fossa, usually coming to within 2. Structures at the L1 level At the transpyloric plane L1 level are: 1 the beginning and the upper limit of the end of the duodenum, 2 the hila of the kidneys, 3 the neck of the pancreas, 4 the origin of the superior mesenteric artery from the aorta. External Oblique The external oblique is the largest and most superficial flat muscle in the abdominal wall.
A plane located halfway between the suprasternal notch and the upper border of the symphysis pubis, this indicates the margin of the transpyloric plane, which in most cases cuts through the pylorus, the tips of the ninth costal cartilages and the lower border of the first lumbar vertebra. Godfried Roomans, Mats Hjortberg and Anca Dragomir. Deep Inguinal ring Superficial Inguinal ring Spermatic Cord Round Lig. Gastric nerve Gastric branches -Pyloric br. Spleen Lien Helium Pancreas Ant: -Root of Mesocolon -Sup. Flat Muscles There are three flat muscles located laterally in the abdominal wall, stacked upon one another.

Approximately midway between the umbilicus and the pubic symphysis, all the aponeuroses move to the anterior wall of the rectus sheath. It corresponds to vertebral level L1.

The body extends from the neck along a line running upwards and to the left from 10cm to reach the hilum of the spleen. It is visible as a vertical groove extending inferiorly from the xiphoid process. The linea alba is a fibrous line that splits the rectus abdominis into two.
The bile duct runs vertically downwards to reach the transpyloric plane 5 cm to the right of the midline, and then for a further 2.

It also divides the supracolic and infracolic compartments, with the liver, spleen and gastric fundus above it and the small intestine and colon below it. It ends in the , which lies approximately 2. The fundus can be represented as a semicircle of 7. We do not undertake any responsibility or liability of any health issues caused by following advise on this website.

Internal Oblique The internal oblique lies deep to the external oblique. This method ligates the blood and nerve supply to muscles medial to the incision, resulting in their atrophy. Vertical Muscles There are two vertical muscles located in the midline of the anterolateral abdominal wall — the rectus abdominis and pyramidalis. At several places, the muscle is intersected by fibrous strips, known as tendinous intersections. The pancreas The best way to mark the pancreas is to start at its neck.
