Bioelectricity
Bioelectricity
Bioelectricity (pronounced: bio-elec-tricity, /ˌbaɪ.oʊ.ɪlɛkˈtrɪsɪti/) is a field of biology and electricity that studies the electrical patterns and signals from biological cells and tissues.
Etymology
The term "bioelectricity" is derived from the Greek words "bios" meaning life and "elektron" meaning amber. Amber, when rubbed, can produce static electricity, hence the association.
Definition
Bioelectricity refers to the production of electric phenomena by living organisms. It is the electric current produced by action potentials along the membranes of cells of certain types of tissue. Bioelectric phenomena are most prominent in nerve and muscle tissues, where they produce rapid, transient changes in the membrane potential.
Related Terms
- Action potential: A short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls.
- Cell membrane: A biological membrane that separates the interior of all cells from the outside environment.
- Nervous system: The part of an animal's body that coordinates its behavior and transmits signals between different body areas.
- Muscular system: An organ system consisting of skeletal, smooth and cardiac muscles.
