[Glomus cell in controlling vascular tone of the carotid labyrinth (Xenopus laevis)].

To clarify the physiological significance of g-s connection (intimate apposition of the glomus cell to the smooth muscle), vascular responses of the carotid labyrinth to both catecholamines and chemoreceptor stimulants were investigated using Xenopus laevis. The results obtained were as follows. Density of dense-cored vesicles in the glomus cell was… (More)
