Abdomen Part 1: Key Terms Flashcards
Arises from the sides of the bodies of the first three lumbar vertebrae
Right crus of diaphragm
Attaches the liver to the anterior abdominal wall and the undersurface of the diaphragm
Falciform ligament
Muscle of the anterior abdominal wall
Rectus Abdominis
Membranous extension of the peritoneum that suspends the stomach and duodenum from the liver, helps support the lesser curvature of the stomach
Lesser Omentum
Lowest horizontal line that joins the tubercles on the iliac crests to help divide the abdominopelvic cavity into nine regions
Intertubercular plane
Ligament between the anterior superior iliac spine and the pubic tubercle
Inguinal ligament
Fibrous band of tissue that stretches from the xiphoid to the symphysis pubis
Linea alba
The internal organs
Viscera
Maintenance of normal body physiology
Homeostasis
Layer of peritoneum that covers the abdominal organs
Visceral peritoneum
Medical measurements used to ascertain how the body is functioning
Vital signs
Opening to the lesser sac
Epiploic foramen
In the male, a small outpocket of the pelvic cavity containing the testes
Scrotal cavity
Physical and chemical changes that occur within the body
Metabolism
Ligament between the spleen and kidney
Lienorenal ligament
Thickened upper margin of the fascia covering the anterior surface of the quadratus lumborum muscle
Lateral arcuate ligament
Potential space between the parietal and visceral peritoneal layers
Peritoneal cavity
Accumulation of serous fluid in the peritoneal cavity
Ascites
Broad muscle that separates the thoracic and abdominopelvic cavities and forms the floor of the thoracic cavity
Diaphragm
Thickened upper margin of the fascia covering the anterior surface of the psoas muscle
Medial arcuate ligament
Arises from the sides of the bodies of the first tow lumbar vertebrae
Left crus of the diaphragm
Horizontal plane that passes through the pylorus, duodenal junction, the neck of the pancreas, and the hilum of kidneys
transpyloric plane
Lower portion of the abdominopelvic cavity that contains part of the large intestines, rectum, urinary bladder, and reproductive organs
Pelvic cavity
Area in the pelvic cavity between the rectum and the uterus where free fluid may accumulate
Rectouterine pouch
Primary compartment of the peritoneal cavity, extends across the anterior abdomen from the diaphragm to the pelvis
Greater sac
Slightly curved line on the ventral abdominal wall that marks the lateral border of the rectus abdominis, visible as a shallow groove when that muscle is tensed
Linea semilunaris
Triangular opening in the external oblique aponeurosis
Superficial inguinal ring
Layer of the peritoneum that lines the abdominal wall
Parietal peritoneum
Peritoneal pouch located behind the lesser omentum and stomach
Lesser sac
Located between the anterior surface of the renal fascia and the posterior area of the peritoneum
anterior pararenal space
Slitilike spaces near the liver, space where fluid may accumulate
Peritoneal recess
Pouch formed by the deflection of the peritoneum from the bladder to the uterus
Vesicouterine pouch
Double fold of the peritoneum attached to the duodenum, stomach, and large intestine; helps support the greater curve of the stomach, known as the fatty apron
Greater omentum
Located directly around the kidney, completely enclosed by renal fascia
Perirenal space
Termination of the falciform ligament, seen in the left lobe of the liver
Ligamentum teres
Single layer of cells that forms the peritoneum
Mesothelium
Found between the posterior renal fascia and the muscles of the posterior abdominal wall
Posterior pararenal space
Ligament between the stomach and the spleen, helps support stomach and spleen
Gastrosplenic ligament
The upper horizontal imaginary line that joins the lowest point of the costal margin on each side of the body to help divide the abdominopelvic cavity into nine regions
Subcostal plane
Right posterior subhepatic space located anterior to the kidney and inferior to the liver where fluid may accumulate
Mosison’s pouch
