摘要: Publisher Summary The approach of visceral polymodal receptors to the study was fruitful for several reasons—(a) testis and epididymis are readily accessible without surgical penetration abdominal cavity; (b) there no gross contractile elements associated with either or and, thus likelihood confusing responses chemical stimuli contraction muscle is reduced; (c) superior spermatic nerve in dog sufficient length studies where needs be electrically stimulated at some distance from site recording. While most would agree that many afferent fibers character, surprisingly little documentation support claim. Thus, knowledge adequate gastrointestinal tract improved their basic physiology will help understand extent which peripheral contributions organ itself contribute altered sensations pain characterize functional bowel disorders.
