During the fasting state, a well-defined pattern of small bowel electrical activity occurs which is known as the interdigestive myoelectric complex or the migrating motor complex (MMC). Which of the following statement(s) is/are true concerning the MMC?
A. This complex consists of a cyclic pattern of spike bursts and muscular contractions that migrate from the duodenum to the terminal ileum and can be divided into four phases
B. The major activity during the MMC occurs during phase I
C. In humans the MMC usually lasts less than one hour
D. Blood levels of the GI peptide, motilin, correlate closely with MMC activity and exogenous motilin can induce the MMC front
