1

Stomach

L sided; 9-11 IC spaces dorsally

2

What separates glandular and non glandular regions of the stomach

margo plicatus

3

mesenteries of stomach

greater omentum, lesser omentum, gastrospelenic ligament, gastrophrenic ligament

4

greater omentum

greater curvature of the stomach to ventral body wall

5

lesser omentum

lesser curvature of the stomach to liver?

6

gastrosplenic ligament

greater curvature of the stomach to spleen

7

gastrophrenic ligament

reflection stomach to diaphragm

8

small intestine

located largely on L side of horse; includes duodenum, jejunum, and ileum

9

Duodenum

descending duodenum primarily on R; passes idly from R to L cd to root mesentery over base cecum then ascending duodenum passes cr on L side of mesentery to transition to jejunum v to l kidney

10

duodenum mesentery

medoduodenum

11

duodenal papilla

major duodenal papilla- opens into bile duct and pancreatic duct
minor duodenal papilla- accessory pancreatic duct

12

jejunum

transition from duodenum to jejunum v to l kindey

13

jejunum mesentery

mesojejunum= "the mesentery"

14

ileum

illeocecal junction and ileocecal fold

15

ileocecal junction

where ileum drops contents into cecum, important for tape worms -> motility issues -> ileum intercecepting into cecum

16

ileocecal fold

important sx landmark goes anti mesenteric side of ileum to tenia if can't find this probably intercecepted

17

Large intestine

cecum, ascending colon, transverse colon, descending colon

18

cecum

V large, predominantly R sided; has base body and apex, apex on V body wall

19

cecocolic orifice

associated with cecal flush

20

mesenteric of cecum

ileocecal fold and cecocolic fold

21

ileocecal fold

anti mesenteric surface of ileum to dorsal band of cecum (thin/ fragile)

22

cecocolic fold

lateral band of cecum to lateral free band of right ventral colon; thicker than ileocecal fold bc 2x connection of mesentery

23

ascending colon d attachment

no d attachment so can move -> colic

24

D anv V portions ascending colon connected by

mesocolon

25

Ascending colon components

RV colon -> sternal flexure -> LV colon -> pelvic flexure -> L D colon -> diaphragmatic flexure -> R D colon

26

transverse colon

v short, R D colon to transverse colon is cr to root of mesentery

27

descending colon

small colon; located in L paralumbar fossa

28

descending colon auscaltation

silent on auscaltation bc contains fecal balls

29

duodenocolic fold

ascending duodenum to small colon

30

Liver

mainly located on R side in 7-15th IC spaces
