**'''Interstitial cells of Cajal''' act as muscle pacemakers and generate a ''basic electrical rhythm''(BER).

**'''Interstitial cells of Cajal''' act as muscle pacemakers and generate a ''basic electrical rhythm'' (BER).

**The BER is able to pass between cells due to the presence of gap junctions. The muscle therefore acts as a syncytium.

*Food in the intestine stimulates peristalsis to occur, and increases the likelihood of an action potential occuring.
