| Muscular fibers of Lacerta viridis with the terminations of nerves. a. Seen in profile. P, P. The nerve end-plates. S, S. The base of the plate, consisting of a granular mass with nuclei. b. The same as seen in looking at a perfectly fresh fiber, the nervous ends being probably still excitable. (The forms of the variously divided plate can hardly be represented in a woodcut by sufficiently delicate and pale contours to reproduce correctly what is seen in nature.) c. The same as seen two hours after death from poisoning by curare. |
