摘要

Experiments were conducted at 25 C on Pachinian corpuscles, obtained from catmesentery. One group of nerve receptors (control) was maintained for 15 min. in a Krebs-Henseleit solution, after which it was fixed, another underwent vibration stimulation with a frequency of 120 Hz and the force of 150 dynes after a 10-minute rest. The results show transverse section of control receptor nerve endings. The nerve endings have elliptical transverse sectional shape, its longitudinal axis is oriented in the direction of fissure in the internal bulb. The plasmatic membrane of the nerve endings forms the folds, which convert into the large apophyses near the fissure.
