. The anatomical record. Anatomy; Anatomy. t/pper Fig. 17 This figure represents the position of the enterographs which were placed at right angles to one another in Bayliss and Starling's experiment (Journ. Physiol., vol. 24, p. 107, fig. 5a) a and 6 are the levers of the enterograph recording the contractions of the inner muscle Figs. IS to 21 These figures represent the initial progressively increasing caudal dilatation synchronous with successive contractions of the inner coat cephalad. Fig. 18 This figure shows contraction of the inner coat from a to 6 simulta- neous with the contraction of the outer coat through one-half the distance from a' to 6'. The contraction wave of the outer and inner coats are preceded by zones of tension or stretching of the muscle fibers produced by the reciprocal elongating actions of the two muscle layers. Fig. 19 This figure represents the contractive wave of the inner coat advanc- ing from 6 to c synchronous with an increasing caudal dilatation produced by the outer coat midway between a', b' to c'. Fig. 20 This figure depicts the caudal dilatation still further advanced from b' to d' at the same time that the inner constriction travels from c to d. Fig. 21 This figure demonstrates the advancing contraction wave of the inner coat occupying the distance from d to e. The caudal dilatation extends from a point midway between b', c' to e'. With each successive rhythmic constriction produced by the cephalic contraction wave in the inner muscle fibers a correspond- ing wave is initiated in the outer muscle layer. The summation of the contrac- tion waves in the outer group of fibers produces the caudal dilatation due to the greater activity of these fibers over that in the inner layer. The balance or equi- librium is upset, therefore, in favor of the outer fibers at this point. 212.
