Q

What are the blind pouch areas?

A

The caecum is the proximal blind pouch of the ascending colon, lying at the level of the ileocecal junction. The terminal ileum opens into the cecum on the medial wall, and the ileocecal valve guards this opening. The appendix is a thin cylindrical organ with a blind attachment to the cecum.

Q

Describe the blood supply and venous drainage of the
small and large intestine

A
24
Q

Descending aorta goes to

A

midgut, foregut and hindgut

25
Q

Midgut has the

A

superior mesenteric atery

26
Q

Hindgut has what artery?

A

inferior mesentric atery

27
Q

Celiac trunk (from aorta) gives blood supply to

A

stomach, liver, spleen, gall bladder (foregut)

28
Q

Superior mesentric:

A

distal duodenum to middle of Transverse colon (2/3 right) (midgut)

29
Q

Inferior mesenteric artery

A

other half of transverse colon to rectum (hindgut)

30
Q

Marginal artery is

A

ensures continuous flow of blood

31
Q

Venous drainage of GIT

A

All veins from gut drain into portal vein - delievers nutrients to liver - portal vein primarily superior (midgut) and inferior mesenteric (hindgut) veins

32
Q

Sympathetic innervation of GIT - overall decreases activity of GIT

A
  • decreases motility and absorption
  • decreases contraction of the circular and
    longitudinal muscle fibers; contraction of
    sphincter muscles (mmt of food)
  • decreased glandular secretions
33
Q

Splanchnic nerves synapse at 3 ganglia:

A

celiac, superior and inferior mesenteric

34
Q

Celiac:
Foregut innerv.

A
  • T5 - T11
35
Q

Superior mesenteric:
midgut

A
  • T10 – T11
  • Duodenum, jejunum, ileum, ascending & transverse colon
36
Q
  • Inferior mesenteric:
A
  • T12 – L2
  • Descending, sigmoid, transverse colon
37
Q

GIT parasympathetic system

A

Cranial and sacral outflow

38
Q

Effects of parasympathetic innveration

A
  • increases motility and absorption
  • Increases contraction and relaxation
    (peristalsis) of longitudinal and
    circular muscle fibers
  • relaxation of sphincter muscles
  • increased glandular secretions
39
Q

Parasymp innervation originates primarily

A

from vagus nerve

40
Q

In the middle medulla, we have the

A

dorsal motor nucleus of vagus (glandular secretion + motor responses in GIT)

41
Q

Sacral preganglionic neurons travel through

A

Lateral horn (travel as
splanchnic n.)
Innervates through plexuses in Lower third intestine &
Rectum

42
Q

Pelvic splanchic

A

are parasympathetic

43
Q

Lumbar splanic are

A

sympathetic

44
Q

Muscle layers of GIT

A

outer longitudinal, circular, submucoas, muscosa
- plexus are where the nerves project into

45
Q

Myenteric plexus is

A

between longitudinal and circular muscle

46
Q

Submucosal/Meissner’s is

A

only found in small & large intest. = secretory actions

46
Q

Submucosal plexus is

A

between circular and mucosa

47
Q

Myenteric (Auerbach) is outer layer and is

A

present from oesophagus to rectum - motor aspects of gut function

48
Q

Rectum will connect

A
  • continuous with sigmoid colon @ S3
  • continuous with anal canal as it penetrates pelvic floor
  • puborectalis – sling, sphincter action
49
Q

What does the celiac trunk supply?

A

stomach, liver, spleen, and gall bladder and proximal duodenum

50
Q

What does superior mesenteric artery supply?

A

Distal duodenum, jejunum, ileum, ascending colon, right half transverse colon

51
Q

What does inferior mesenteric artery supply?

A

left half transverse, descending and sigmoid colon

52
Q

Superior mesenteric ganglion innervates the small intestine

A
53
Q

Inferior mesenteric ganglion innervates

A

urinary bladder and orgasm, and vaginal contraction
