| Question | Answer |
|---|---|
| location of left lobe of pancreas | along greater curvature of stomach in deep leaf of greater omentum |
| location of right lobe of pancreas | along descending duodenum in mesoduodenum |
| location of body of pancreas | at cranial duodenal flexure/pylorus |
| location of spleen | in superficial leaf of greater omentum |
| peritoneum that suspends abdominal organs to dorsal body wall | greater omentum, mesoduodenum, mesojejunum, mesoileum, mesocolon, mesorectum |
| peritoneum that suspends abdominal organs to ventral body wall | lesser omentum, falciform ligament, median ligament of the urinary bladder |
| aka dorsal mesogastrium | greater omentum |
| aka ventral mesogastrium | lesser omentum and falciform ligament |
| celiac a. supplies | foregut |
| cranial mesenteric a. supplies | midgut |
| caudal mesenteric a. supplies | hindgut |
| left gastric a. supplies | left side of stomach and terminal esophagus |
| splenic a. supplies | spleen, left side of stomach, left lobe of pancreas, greater omentum |
| hepatic a. supplies | liver, right side of stomach, body and right lobe of pancreas, inital portion of duodenum, greater omentum |
| caudal pancreaticcoduodenal a. supplies | right lobe of pancreas, duodenum |
| mesenteric ileal a. supplies | ileum |
| colic br. of ileocolic a. supplies | initial part of ascending colon |
| cecal a. supplies | cecum and ileum via antimesenteric ileal a. |
| right colic a. supplies | ascending colon |
| middle colic a. supplies | transverse colon |
| left colic supplies | descending colon |
| location of right kidney | retroperitoneally against sublumbar muscles from L1-L3 |
| Location of left kidney | retroperitoneally against sublimbar muscles from L2-L4, |
| Location of pelvic urethra | internal |
| location of penile urethra | external |
| muscle that surrounds pelvic urethra | urethralis m. |
| Muscle of urinary bladder | detrusor m. |
| pampiniform plexus | formed via testicular vein. around the controted testicular artery for heat exchange. |
| tunica dartos | fibromuscular layer of scrotal wall. formed via connective tissue and smooth muscle. extends b/w testes (scrotal septum) |
| scrotal septum | separates testes into separate compartments |
| bulbospongiosus m. | covers the bulb of the penis. contraction causes increased pressure in urethra |
| ischiocavernosus m. | cover the crura. supports the erect penis |
| ischiourethralis m. | form ring around dorsal veins of penis. contraction restricts venous return, helping maintain penile tumescence |

| tuboterine junction | opening into uterine horn |
| mesosalpinx | serous membrane. attaches to mesovarium and forms much of the wall of the ovarian bursa |
| internal uterine ostium | uterine opening. directed dorsally |
| external uterine ostium | vaginal opening. directed ventrally |
| fornix | cranial most part of vagina. extends ventral to cervix. caudal portion retroperitoneal |
| mucosal lining of fornix | longitudinal folds with smaller transverse folds. able to extend both diameter and length |
| external urethral orifice | opening of urethra. marks vaginovestibular junction |
| urethral tubervle | soft tissue projection from floor at external urethral orifice |
| vestibular bulbs | erective tissue in the lateral walls |
| constrictor vestivbuli m. | striated muscle. constricts wall of vestibule. |
| rima pudendi | vulvar cleft |
| Perineal body | fibromuscular complex b/w the anal canal and the urogenital tract |
| features torn during OHE | 1.suspensory ligaments 2.mesovarium 3.mesometrium 4.round ligaments |
| features ligated/cut during OHE | 1.ovarial a. and v. 2.uterine a. and v. 3. uterine body |
| caudal epigastric a. supplies | caudoventral aspect of abdominal wall |
| external pudendal a . supplies | inguinal region and superficial tissues of caudoventral abdomen |
| medial circumflex femoral a. supplies | adjacent tissues. muscles near proximoedial thigh |

| descending genicular a. supplies | medial aspect of genual jt |
| cranial tibial a. supplies | craniolateral m. of crus |
| medial saphenous v. used commonly in | cats |
| lateral saphenous v. used commonly in | dogs |
| superficial inguinal LN drains | caudoventral abdomen, ventral perineum, medial aspect of pelvic limb. |
| specific drainage of superficial inguinal LN in female | abdominal and inguinal mammary glands |
| specific drainage of superficial inguinal LN in male | penis, prepuce, scrotum |
| popliteal LN drains | distal portion of pelvic limb |
| clinical range of lumbosacral pexus | L4-S3 |
| Femoral n. injury | inability to extend genual jt. inability to bear wt on pelvic limb |
| obturator n. injury | inability to adduct limb. limb "slides out" on slippery surface |
| common fibular n. injury | inability to flex tarsal jts and extend digital jt. "knuckled over". loss of sensation over dorsum of paw |
| tibial n. injury | inability to extend tarsal jts and flex digital jt. "dropped hock". loss of sensation on plantar surface of paw |
