Front 10

With which structures is the celiacomesenteric plexus associated?

Back 10

The celiac a. and the craniomesenteric a.

Front 11

T or F:
The celiacomesenteric plexus is composed of paired cranial mesenteric ganglia and an unpaired celiac ganglion.

Back 11

False you fool!
The celiac ganglia are PAIRED
The cranial mesenteric ganglion is UNPAIRED
Try and get it right next time...

Front 12

T or F:
The caudal mesenteric ganglion is the last chance for a preganglionic sympathetic neuron to synapse.

Back 12

True!
The caudal mesenteric ganglion sprouts the hypogastric nn. which provide sympathetic innervation to the pelvic viscera.

Front 13

Front 18

T or F:

Back 18

True (from what I can tell)
The celiac, cranial and caudal mesenteric aa. all supply blood to the stomach and intestine and all three are unpaired.

Front 23

Name ALL of the structures supplied by the celiac artery!!!

Back 23

Spleen
Pancreas
Stomach
Esophagus
Liver
Gall Bladder
Duodenum
Lesser omentum
Greater omentum

Front 24

One of these things is not like the other...which one?
Spleen
Pancreas
Ileum
Stomach
Liver
Duodenum
(hint...think blood supply!)

Back 24

Ileum! All the others have blood supplied by the celiac artery! It supplies blood to:
Spleen
Pancreas
Stomach
Esophagus
Liver
Gall Bladder
Duodenum
Lesser omentum
Greater omentum

Front 25

What are the major divisions or branches of the cranial mesenteric a. and where do they supply?

Back 25

Commin colic - colon
Caudal pancreaticoduodonal - pancreas and distal duodenum
Jejunal - jejunum
Ileal - ileum

Front 26

What are the three branches of the common colic a.?

Back 26

Ileocolic
Right colic
Middle colic
(possibly accessory colic)

Front 27

T or F:
The mesenteric ileal br. of the ileocolic a. gives rise to the antimesenteric ileal br.

Back 27

False!
The antimesenteric ileal br. arises from the cecal a. and runs on the ileum opposite to the mesenteric ileal br.

Front 28

Don't identify any of this stuff. Just kidding!

Back 28

A - Middle colic a.
B - Common colic a.
C - Right colic a.
D - Cecal a.
E - Ileocolic a.
F - Antimesenteric ileal br.
G - Mesenteric ileal br.

Front 29

T or F:
The iliocolic a. supplies blood directly to the ileum and colon.

Back 29

False (technically)
The iliocolic a. terminates once it has branched into the colic br., the cecal a., and the mesenteric ileal br. (also gives rise to a cecal br.). Therefore, the iliocolic doesn't direcly supply blood to any structure.
