Abdomen And Pelvis Flashcards
Origin of diaphragm.
Sternal part - xiphoid process
Costal part - inner aspect of lower 6 ribs
Vertebral part - right and left crus.
Medial arcuate ligament.
Thickening of the psoas fascia.
Lateral arcuate ligament.
Thickening of the anterior layer of the thoraco-lumbar fascia.
Openings in the diaphragm.
T8 - IVC and right phrenic nerve.
T10 - esophagus and right and left vagus
T12 - aorta, azygos vein and thoracic duct.
How do the sympathetic chain and subcostal nerve and vessels enter the abdomen.
Sympathetic chain enters abdomen behind the medial arcuate ligament.
Subcostal nerve and vessels enter the abdomen behind lateral arcuate ligament.
Foramen of Morgagni.
Also known as space of Larry.
A small defect between sternal and costal origins of the diaphragm.
Superior epigastric vessels enter the abdomen through this opening.
Muscles of the posterior abdominal wall.
Psoas major, quadratus lumborum, transversus abdominins.
Where is lumbar plexus formed.
In the substance of psoas major.
Nervus furcalis.
Nervus furcalis is the ventral ramus of L4.
It’s takes part in the formation of the lumbar and sacral plexus.
Joins with L5 to form sacral plexus.
Terminal branches of abdominal aorta.
Common iliacs at the level of L4.
Ventral branches of abdominal aorta.
Coeliac trunk at the level of T12.
Superior mesenteric artery at the level of L1.
Inferior mesenteric artery at the level of L3.
Lateral branches of the abdominal aorta.
Inferior thoracic. Middle suprarenal. Renal. Gonadal. Dorsal branches.
Other branches of abdominal aorta.
4 pairs of lumbar arteries and 1 medial sacral artery.
L5 is supplied by what artery.
Ilio-lumbar artery branch of posterior division of internal iliac.
Nutcracker sign.
Refers to the Left renal vein when it gets obstructed between the abdominal aorta and the superior mesenteric artery.
Since the left gonadal vein drains into the left renal artery.
Decreased flow of blood causes pooling of blood in left kidney and the left testes. (Nutcracker sign)
Branches of the coeliac trunk.
3 branches - Left gastric, splenic and common hepatic.
Splenic branch gives pancreatic, short gastric and left gastroepiploic branches.
Common hepatic gives right gastric branch and divides into hepatic artery proper and gastroduodenal artery.
Gastroduodenal artery divides into right gastroepiploic and superior pancreatico-duodenal branches.
Parts of the portal vein.
Supraduodenal part.
Retroduodenal part.
Infraduodenal part.
Relations of the supraduodenal part of the portal vein.
Anterior and to the right - bile duct.
Anterior and to the left - hepatic artery
Posterior - IVC.
Relations of the infraduodenal part of the portal vein.
Anterior - neck of pancreas.
Posterior - IVC.
Relations of the retroduodenal part of the portal vein.
Anterior and to the right - bile duct
Anterior and to the left - gastroduodenal artery
Posterior - IVC.
Branches of the superior mesenteric artery.
Inferior pancreaticoduodenal. Jejunal and ilial branches. Middle colic. Right colic. Ilio-colic
Ilio-colic further divides into ascending and descending branches.
Descending branches of ilio-colic give 1. Anterior caecal 2. Posterior caecal 3. Appendicular 4. Ilial
Appendicular artery is a branch of.
Descending branch of ilio-colic.
Recurrent appendicular artery is a branch of.
Appendicular or posterior caecal.
Appendicular artery of Sheshachalam.
POSTERIOR CAECAL.
Branch of posterior caecal branch of descending branch of ilio-colic artery.
Branches of the inferior mesenteric.
Left colic.
Sigmoid branches.
Superior rectal artery (continuation of inferior mesenteric)
Boundaries of inguinal ligament.
Anterior wall - external oblique
Lateral wall - internal oblique and transverse abdominis
Posterior wall - fascia transversalis
Medial wall - conjoint tendon
Roof - conjoint tendon
Floor - external oblique and inguinal ligament.
Coverings of the testes.
External spermatic fascia - from ext. oblique aponeurosis
Cremasteric fascia - from cremaster.
Internal spermatic fascia - from fascia transversalis
Tunica vaginalis
Tunica albuginea
Tunica vasculosa
Median umbilical ligament.
Obliterated urachus/ allantois.
Persistence of urachus/ allantois.
Weeping umbilicus.
Medial umbilical ligament.
Obliterated umbilical artery
Lateral umbilical ligament.
Fold of peritoneum which covers inferior epigastric vessels.
Contents of the spermatic cord.
Vas deferens. Artery to vas Cremasteric artery Testicular artery Pampiniform plexus of veins Genital branch of genitofemoral nerve Lymphatics from the testes.
Anterior relations of the right kidney.
Right suprarenal gland. Liver 2nd part of duodenum Ascending colony and hepatic flexure. Small intestines.
Anterior relations of the left kidney.
Left suprarenal gland. Stomach Splenic artery Spleen Pancreas Splenic flexure and descending colon. Small intestines.

Root of the mesentry extends from.
DJ flexure to Right sacroiliac joint.
Structures crossed by the root of mesentry.
3rd part of duodenum. Aorta IVC Right psoas major R ureter
Boundaries of the epiploic foramen.
Anterior - lesser omentum containing hepatic artery, portal vein and bile duct.
Posteriorly - IVC, right suprarenal gland and T12 vertebra body
Superiorly - caudate lobe of the liver (caudate process)
