Flashcards in Intestinal and Colonic Motility Deck (10):
1

Name the 4 things involved in intestinal motility

segmentation

peristalsis

intestino-intestinal reflex

migrating motility complex

2

Explain segmentation in the small intestines

segmentation breaks the bolus into two sections, then brings them back together for mixing

3

Explain peristalsis in the small intestines

Peristalsis is a muscle contraction that pushes the bolus down the length of the intestines

4

Give 3 characteristics of the intestino-intestinal reflex

contractilve activity is inhibited proximal to an obstruction

prevents movement of ingesta into distal segment

mediated by extrinsic (autonomic) nervous system

5

Name some disorders of the intestinal tract (also known as ileus)

viral enteritis (ex: parvo)

inflammatory bowel disease

post-anesthetic, post-surgical

electrolytes - decreased K+ or Ca2+

intestinal fibrosis

autonomic neuropathy

6

Name the 5 things involved in colonic motility of the proximal colon

cecum and ascending colon

segmentation

anti-peristalsis

mixing of contents

extraction of water

7

Name the 4 things involved in colonic motility of the distal colon

descending colon

storage

mass movement

defecation

8

Clinical signs of feline constipation (6)

reduced defecation

dyschezia

unusual patterns

dry/hard feces

hematochezia

anorexia/lethargy

9

Name the 3 steps of constipation

constipation

obstipation (failure of colonic motility)

megacolon (loss of colon form)

 

10

Name the pathogenesis of feline constipation (4)

idiopathic

pelvic stenosis

nerve injury

manx deformity
