ANSWER

Migrating motor complex (gut motility) [absite, p.214]
– Phase I – rest
– Phase II – acceleration and gallbladder contraction
– Phase III – peristalsis
– Phase IV – deceleration
absite review, p.214

Motilin is most important hormone in migrating motor complex [absite, p.214]

From Wikipedia, the free encyclopedia
Migrating motor complexes (or migrating myoelectric complex) are waves of activity that sweep through the intestines in a regular cycle during fasting state.
These motor complexes help trigger peristaltic waves which facilitate transportation of indigestible substances such as bone, fiber and foreign bodies from the stomach, through the small intestine past the ileocecal sphincter into the colon.

The MMC originates in the stomach roughly every 75–90 minutes during the interdigestive phase (between meals) and is responsible for the rumbling experienced when hungry.
It also serves to transport bacteria from the small intestine to the large intestine, and to inhibit the migration of colonic bacteria into the terminal ileum.
The MMC is thought to be partially regulated by motilin which is initiated in the stomach as a response to vagal stimulation, and does not depend on extrinsic nerves directly.

States that MMC starts in antrum and duodenum.
Migrating motor complex cycle duration is determined by gastric or duodenal origin of phase III

ABSITE KILLER Q&A and ABSITE REVIEW PRACTICE TEST

ABSITE KILLER Q&A

Examination Content

Since 2006 the ABS has offered the ABSITE as a junior level (PGY-1 and -2) and senior level (PGY-3 to -5) examination. Both the junior- and senior-level versions consist of approximately 225 multiple-choice questions; examinees are given five hours to take the exam. For the junior-level exam, 60% of the examination focuses on basic science, while 40% centers on the management of clinical surgical problems. In the senior-level exam, 20% of the exam focuses on basic science and 80% on clinical management.
