Basic mechanical rhythm in the rat small intestine.
The basic electrical rhythm (BER) of the small intestine in rat proves its physiological usefulness in generating the basic mechanical rhythm (BMR) as a specific form of muscular tonus in the interdigestive (respite) phases BMR is susceptible to amplitude modifications under the influence of factors that are intrinsic or extrinsic to the muscle fibre, an influence which is exerted either directly over the contractile phenomenon, or by means of electrical phenomena. Recording of BMR is made possible through the use of transducers appropriate in point of sensitivity and of size for the area from which information about the contraction force is collected.
