Q

peritoneum is a continuous membrane

A

PARIETAL = body wall

VISCERAL = organ

creates the peritoneal cavity between the visceral and parietal layers

contain a small amount of lubricating fluid

Q

organs with mesentery

A

covered in visceral peritoneum

visceral peritoneum wraps behind the organ to form a double layer - mesentery

mesentery suspends the organ form the posterior abdominal wall - very mobile

Q

intraperitoneal organs classifications

A 
liver and gall bladder
stomach
spleen
parts of small intestine
transverse colon
17
Q

retroperitoneal organs

A 
kidneys
adrenal gland
pancreas
ascending colon
descending colon
18
Q

peritoneal formations

A

mesentery
usually connects organ to posterior body wall

omentum
double layer of peritoneum that passes from stomach to adjacent organs

peritoneal ligaments
double layer of peritoneum connects organs to one another or body wall

19
Q

mesentery

A

have a core of connective tissue with blood and lymph nodes, nerve, lymph nodes and fat

high level mobility

20
Q

mesentery proper

A

suspends small intestine from posterior wall

21
Q

omentum - greater

A

four-layered
hangs like apron

attaches the greater curvature of stomach to transverse colon

22
Q

omentum - lesser

A

double-layered

runs between lesser curvature of stomach and duodenum to liver

has a free edge

23
Q

ascites

A

collection of fluid in the peritoneal cavity

can be drained from the peritoneal cavity by a procedure called paracentesis

24
Q

nerves of the abdomen

A

viceral afferents - sensory nerves

enteric nervous system

25
Q

sympathetic nerves

A

between T5 to L2
eneter sympathetic chains but dosent synapse

leaves with abdominopelvic splanchnic nerves

synapse at per vertebral ganglia

26
Q

postsynaptic sympathetic nerve fibres

A

pass from the pervertebral ganglia on [[

periaterial plexus as they hitch a ride with the arteries

27
Q

adrenal glans - sympathetic nerves

A

T10-L1

synapses directly onto cells

28
Q

parasympathetic nerves

A

vagus nerve

pelvic splanchnic organs

29
Q

abdominal pain

A

forgot - epigastric region
T6-T9

midgut - umbilical region
T8-T12

hindgut - pubic region
T12-L2

30
Q

thoracobdominal nerves

A

7th - 11th intercostal nerves

31
Q

subcostal nerve

A

T12

32
Q

lliohypogastric nerve

A

half of L1 anterior ramus

33
Q

ilioinguinal nerve

A

other half of L1 anterior ramus

34
Q

appendicitis

A

midgut organ
T8-T10

irritates the parietal peritoneum in the right iliac fossa
