Tiberius Cavallo made an electroscope in 1770 with pith balls at the end of silver wires. [3] Modern electroscopes usually use balls made of plastic. In order to test the presence of a charge on an object, the object is brought near to the uncharged pith ball. If the object is charged, the ball will be attracted to it and move toward it.
Electrophysiology (from Greek ἥλεκτ, ēlektron, "amber" [see the etymology of "electron"]; φύσις, physis, "nature, origin"; and -λογία, -logia) is the branch of physiology that studies the electrical properties of biological cells and tissues.
Gilbert used the versorium to test whether different materials were "elektrics" (insulators, in modern terms) or non-"elektrics" ().While he didn't devise a theory to explain his findings, it was a good example of how science was starting to change by incorporating empirical studies at the dawn of the Age of Reason.

The discipline of anatomy can be subdivided into a number of branches, including gross or macroscopic anatomy and microscopic anatomy. [9] Gross anatomy is the study of structures large enough to be seen with the naked eye, and also includes superficial anatomy or surface anatomy, the study by sight of the external body features.
Headline from the New York Times article on Szczepanik's telectroscope (April 3, 1898). Nevertheless, the word "telectroscope" was widely accepted. It was used to describe the work of nineteenth century inventors and scientists such as Constantin Senlecq, [6] George R. Carey, [7] Adriano de Paiva, and later Jan Szczepanik, who with Ludwig Kleiberg obtained a British patent (patent nr. 5031) [8 ...
Mathematics – graph/network theory, population modeling, dynamical systems, phylogenetics. Medicine – biophysical research that emphasizes medicine. Medical biophysics is a field closely related to physiology. It explains various aspects and systems of the body from a physical and mathematical perspective.
The following outline is provided as an overview of and topical guide to physiology: . Physiology – scientific study of the normal function in living systems. [1] A branch of biology, its focus is in how organisms, organ systems, organs, cells, and biomolecules carry out the chemical or physical functions that exist in a living system.
Physiology (/ ˌ f ɪ z i ˈ ɒ l ə dʒ i /; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία () 'study of') [1] is the scientific study of functions and mechanisms in a living system.
