Text Appearing Before Image:
ecently I read a paper on the normalstomach (Lancet, July 29, 1922). How-simple it seemed before one reallj tackledthe subject in the light of modern physi-ology! One always realized that the variedappearances of the stomach were largelydependent on variations in tonic action,but one did not realize how difficult it was,and is, to lay real hold of the conception ofthis function of muscle of which we speakso gliblv and know so little. We always they are stretched or in a state of con-traction, namely, whether the stomach isor small it is not a contraction, buta posture of muscle, the nearest word thatSherrington finds to describe the action.1 would strongly recommend to all w ho arc-intcrestccl in studying the foundations onwhich we are working, the masterlj paperb\ Sherrington, published in IQ15, onPostural Activitj of Muscle and Nerve*(Brain, xxxviii, part 3, p. 10,1.1 Our conception of a stomach as h\ per-tonic or atonic is quite likely incorrect.A muscle fiber probably has the same

Fig. 3. Stomach opened down the great curvature andmucous membrane dissected off. Note the innermostcoat, the oblique band running down either side ofthe lesser curvature and branching out fanlike, butconfined to this portion of the stomach, leaving anarrow gap along the lesser curvation between tiretwo sides. Jefferson has shown that in the upper 2inches, this band is quite free from the underlyingmuscle wall, but lower down it spreads out on eitherside, fanlike, and its fibers intermingle and fuse withthe fibers of the circular coat, forming a network inwhich the actual libers appear to join each other. think of a muscle as a bundle of fiberswhich, by contraction, does certain work.Vaguely we realize that muscle has alsoanother function, that of tonic action.Tone, (derived from the Greek t«y«>I stretch,) we regard as mechanical tensionexerted bv muscle fibers, and so it is, to acertain point; but this is only a halt-truth,and we must go a great deal further to getat the whole t
