Q

Function of Sympathetic innervation to Stomach;

A
  1. Vasomotor

2. Inhibit gastric muscles except Pylorus

21
Q

Function of Parasympathetic fibres to Stomach;

A
  1. Secretomotor
  2. Stimulate Gastric muscles
  3. Relaxes pylorus
22
Q

Anterior vagal trunk is derived from the;

A

Left Vagus

23
Q

Anterior vagal trunk divided into

A

Hepatic branch and

Gastric branch (nerve of Latarjet)

24
Q

Hepatic branch of Anterior vagal trunk is divided into

A

Ascending and Descending Branch

25
Q

Ascending hepatic branch (of anterior vagal trunk) supplies;

A
  1. Liver

2. Extraheparic biliary system

26
Q

Descending hepatic branch (of Anterior vagal tone) supplies;

A

Pyloric part of Stomach

27
Q

Posterior vagal trunk derived from;

A

Right vagus

28
Q

Three branches of Posterior vagal trunk;

A
  1. Coeliac branch
  2. Gastric branch (nerve of Latarjet)
  3. Nerve of Grassi
29
Q

Nerve of Grassi supplies;

A

Fundus of the stomach

Nerve of Grassi (branch of Posterior vagal trunk)

30
Q

Coeliac branch of Posterior vagal trunk gives contribution to

A

Coeliac plexus

31
Q

Truncal vagotomy refers to

A

Cutting of Both Anterior and Posterior Vagal trunk

32
Q

Selective vagotomy refers to

A

Sparing the Hepatic and Coeliac branch

Rest others branches will be cut off

33
Q

The main disadvantage of Truncal or Selective vagotomy

A

Gastric emptying is affected

34
Q

To prevent the side effect of Truncal or Selective vagotomy (i.e; gastric emptying) what we can do

A

High Selective Vagotomy

In which only Criminal nerve of Grassi is resected

Gastric emptying is not affected as the nerve to pylorus (nerve of Laterjet) is spared

35
Q

‘Criminal’ Nerve of Grassi- it is implicated as ‘criminal’

because

A

it is often missed during
a Vagotomy procedure and can
Result in Recurrent peptic
ulcer disease

36
Q 
Four parts of duodenum (size & orientation)
1st part -

Extends from L1-L3
Measures 8-l0 cm

3rd part: Horizontal part
Measures 10cm

4th part: smallest part
Measures 2.5cm
continues as Jejunum

37
Q

Common Bile Duct divided into 3 parts by

A

1st part Duodenum

38
Q

A

Above 1st part of Duodenum: Supra duodenal part of CBD

Behind 1st Part of Duodenum: Retro duodenal part of CBD

Below 1st part of Duodenum: Infra duodenal part of CBD

39
Q

Three structures, Behind the 1st part of Duodenum

A
