In endoscope observation, acquiring shape information of a lesion area is highly demanded for objective and statistical judgment. For in-vivo applications, a high-speed measurement is also considerable. Therefore, we proposed an electronic endoscope system that equips an imagefiber and a laser scanner, and achieves the high-speed measurement by using the… (More)
In general, skeletal muscle activity has been understood on the basis that the muscle is functionally consisted of contractile element and elastic element. In this paper it has been attempted to clarify the specific role of the geniohyoid muscle which is one member of the oro-basal muscular system, because our previous reports suggested an elastic… (More)
Two different types of elastic behaviors could be distinguished in the twitch contraction curve of the isolated frog geniohyoid muscle under changing of chemical conditions; one was negative oscillation that occurred after completion of the relaxation phase which was sequential to a typical cyclic pattern demonstrated in the contraction and relaxation… (More)
In the frog tongue, there is an interesting physiological phenomenon named water response. Accordingly, it is said that the frog gustatory nerve contains water fiber. In spite of much experimental data, the nature or establishing process of water response is now not yet clear. As a common process the enhancement effect of Ca++ on the water response is well… (More)
The responses of the bullfrog lingual surface to continuous tactile flow stimulation for 3 minutes were characterized by a presence of conspicuous off-response. At that time the on-responses of the lingual surface were uniform in shape. The off-responses in the same situation were not uniform but multiform against expectation. These multiform off-responses… (More)
NaCl at various concentrations applied to the dorsal surface of the bullfrog tongue induced slow potential changes across the tongue. They were almost in parallel with changes in impulse discharges simultaneously recorded from the glossopharyngeal nerve.
