Ch. 4, 5, & 6 Flashcards
Lowest horizontal imaginary line that joins the tubercles on the iliac crests
intertubercular plane
Mid horizontal imaginary line that joins the lowest point of the costal margin on each side of the body
subcostal plane
Uppermost horizontal plane that passes through the pylorus, the duodenal junction, the neck of the pancreas, and the hilum of the kidneys
transpyloric plane
Broad muscle that separates the thoracic and abdominopelvic cavities and forms the floor of the thoracic cavity
diaphragm
Ligament between the anterior superior iliac spine and the pubic tubercle
inguinal ligament
Thickened upper margin of the fascia covering the anterior surface of the quadratus lumborum muscle
lateral arcuate ligament
Arises from the sides of the bodies of the first two lumbar vertebrae
left crus of the diaphragm
Fibrous band of tissue that stretches from the xiphoid to the symphysis pubis
linea alba
Slightly curved line on the ventral abdominal wall that marks the lateral border of the rectus abdominis
linea semilunaris
Thickened upper margin of the fascia covering the anterior surface of the psoas muscle
medial arcuate ligament
Lower portion of the abdominopelvic cavity that contains part of the large intestine, the 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 space
Muscle of the anterior abdominal wall
rectus abdominis muscle
Arises from the sides of the bodies of the first three lumbar vertebrae
right crus of the diaphragm
In the male, a small outpocket of the pelvic cavity containing the testes
scrotal cavity
Triangular opening in the external oblique aponeurosis
superficial inguinal ring
Formed by the deflection of the peritoneum from the bladder to the uterus
vesicouterine pouch
The internal organs
viscera
Located between the anterior surface of the renal fascia and the posterior area of the peritoneum
anterior pararenal space
attaches the liver to the anterior abdominal wall and undersurface of the diaphragm
falciform ligament
Single layer of cells that form the peritoneum
mesothelium
Primary compartment of the peritoneal cavity; extends across the anterior abdomen from the diaphragm to the pelvis
greater sac
Ligament between the stomach and the spleen; completely enclosed by renal fascia
gastrosplenic ligament
Located directly around the kidney; completely enclosed by renal fascia
perirenal space
Accumulation of serous fluid in the peritoneum cavity
ascites
Membranous extension of the peritoneum that suspends the stomach and duodenum from the liver; helps support the lesser curvature of the stomach
lesser omentum
Layer of the peritoneum that lines the abdominal wall
parietal peritoneum
