The arteries that supply the superficial part of the ventral abdominal wall are branches of the ______________.
superficial epigastric arteries
Which artery emerges from the superficial inguinal ring?
What are its parent and grandparent vessels?
external pudendal
pudendoepigastric trunk;
a branch of the deep femoral artery
Emerging from the dorsolateral abdominal wall, caudal to the last rib, are superficial branches of the
cranial abdominal artery
Which arteries supply the following regions of the abdominal wall:
craniodorsal, cranioventral, caudoventral, caudodorsal
craniodorsal - cranial abdominal artery
cranioventral - cranial epigastric artery
caudoventral - caudal epigastric artery
caudodorsal - deep circumflex iliac artery
drains the mammae, prepuce, scrotum, and ventral abdominal wall as far cranially as the umbilicus
superficial inguinal lymph nodes
most of the afferent lymph vessels of the thoracic wall and deep structures of the limb drain into this node
axillary lymph nodes
ventral branch of L1; has medial and lateral branches
cranial iliohypogastric nerve
ventral branch of L2; has medial and lateral branches
caudal iliohypogastric nerve
ventral branch of L3; medial and lateral branches
ilioinguinal nerve
ventral branch of L4
lateral cutaneous femoral nerve
formed by ventral branches of L3 and L4
genitofemoral nerve
connective tissue layer that is located between the mesothelium (peritoneum) and the muscular walls of the abdominal cavity and the organs
transversalis fascia
double layer of peritoneum extending from the body wall to the organs within the abdominal and pelvic cavities
connecting peritoneum / mesentery or “meso-”
fat-filled remnant of ventral mesentery that extends cranially from the umbilicus to the diaphragm; contained the umbilical vein in the fetus
falciform ligament
remnant of the fetal umbilical vein; thickened ridge of the falciform ligament that extends cranially from the umbilicus to the liver where it disappears between the left medial and quadrate lobes of the liver
round ligament of the liver
remnant of ventral mesentery that contained the urachus and umbilical arteries in the fetus; extends caudally from the umbilicus to the ventral aspect of the bladder
median ligament of the bladder
ring-like internal region where the peritoneum extends into the inguinal canal
vaginal ring
The greater omentum is a dorsal mesentery that covers over, and often becomes entangled with, the ___________ and ________; attaches to the dorsal body wall and to the _______________________; has superficial and deep leaves
jejunum and ilieum
greater curvature of the stomach
The superficial leaf of the greater omentum encompases the _______ on the left side
spleen
The deep leaf of the greater omentum is adjacent to the abdominal organs and attaches to the dorsal body wall; encompasses the ____________________
left lobe of the pancrease dorsally
Enclosed space between the superficial and deep leaves of the greater omentum.
Through what can one gain access to this space?
omental bursa
epiploic foramen
What contains the right lobe of the pancreas?
Mesoduodenum
