Preparation of nerve endings
Nerves have been a topic in physiology since the beginning of the 19th century. The focus shifted from basic understanding of nerve conduction to more complex questions of the interactions in the nervous system and its detailed anatomic structures. This picture from 1921 comes from a series of anatomical preparations and shows nerve endings at a magnification of 2600x.
