[Anatomy] The Abdomen quizzes – Part 4 (20 questions)

Inferiorly, the posterior surfaces of the kidney are related to the quadratus lumborum muscle and the subcostal, iliohypogastric, and ilioinguinal nerves and vessels

The diaphragm is attached on each side to the medial and lateral arcuate ligaments, which are thickenings of the fascia covering the psoas major and quadratus lumborum muscles, respectively

The cystic artery commonly arises from the right hepatic artery in the angle between the common hepatic duct and the cystic duct

The suprarenal cortex derives from mesoderm and secretes corticosteroids and androgens. These hormones cause the kidneys to retain sodium and water in response to stress

The renal papillae empty into the minor calices, which empty into major calices which in turn empty into the pelvis of the ureter

The superior suprarenal arteries are provided by the inferior phrenic. The middle suprarenal arteries are provided by the abdominal aorta and the inferior suprarenal arteries are provided by the renal artery

The porta hepatis gives passage to the portal vein, hepatic artery, hepatic nerve plexus, hepatic ducts, and lymphatic vessels

The crura of the diaphragm are musculotendinous bundles that arise from the anterior surfaces of the bodies of the superior three lumbar vertebrae, the anterior longitudinal ligament, and the intervertebral discs

The portion of the lesser omentum extending between the porta hepatis of the liver and the duodenum (the hepatoduodenal ligament) encloses the portal triad

The semilunar left suprarenal gland is related to the spleen, stomach, pancreas, and left crus of the diaphragm

The diaphragm, the chief muscle of inspiration, descends during inspiration. Only its central part moves because its periphery, as the fixed origin of the muscle, attaches to the inferior margin of the thoracic cage and the superior lumbar vertebrae

The round ligament of the liver is the fibrous remnant of the umbilical vein that carried well-oxygenated and nutrient-rich blood from the placenta to the fetus

The central tendon of the diaphragm has no bony attachments and is incompletely divided into three leaves, resembling a wide cloverleaf. Although it lies near the center of the diaphragm, the central tendon is closer to the anterior part of the thorax. The inferior vena cava perforates the central tendon. The aortic hiatus is formed by the right and left muscular crura

The paraumbilical veins of the anterior abdominal wall (portal system) anastomosing with superficial epigastric veins (systemic system), when dilated, produce caput medusae

The suprarenal glands are located between the superomedial aspects of the kidneys and the diaphragm

At the concave medial margin of each kidney is a vertical cleft, the renal hilum, where the renal artery enters and the renal vein and renal pelvis leave the renal sinus. At the hilum, the renal vein is anterior to the renal artery, which is anterior to the renal pelvis

The nerves of the kidneys and suprarenal glands are derived from the celiac plexus, the lesser and least thoracic splanchnic nerves, and the aorticorenal ganglion

The common hepatic artery extends from the celiac trunk to the origin of the gastroduodenal artery. The proper hepatic artery extends from the origin of the gastroduodenal artery to its bifurcation into right and left hepatic branches

The mucosa of the neck of the gallbladder spirals into a fold known as the spiral valve, which keeps the cystic duct open so that bile can easily divert into the gallbladder when the distal end of the bile duct is closed, or so bile can pass to the duodenum as the gallbladder

The hepatic veins, formed by the union of the central veins of the liver, open into the inferior vena cava just inferior to the diaphragm
