Electrophysiology: The biomedical field dealing with the study of electric activity in the body. Electrophysiology includes the study of the production of electrical activity and the effects of that electrical activity on the body. See, for example: Electrophysiologic retinal testing ; and Electroph...
Electroretinogram: Abbreviated ERG. An electroretinographic recording. See: Electroretinography....
Electroretinography: Abbreviated ERG. A test in which the electrical potentials generated by the retina of the eye are measured when the retina is stimulated by light.
In an ERG, an electrode is placed on the cornea at the front of the eye. The electrode measures the electrical response of the ro...

Electrosurgery: Instead of using a scalpel, the surgeon utilizes a heat-generating electrical device to burn or vaporize tissue in order to remove it and minimize and halt bleeding....
Elephantiasis: Lymphatic filariasis, a mosquito-borne parasitic disease caused by tiny thread-like worms that live in the human lymph system. Best known from dramatic photos of people with grossly enlarged or swollen arms and legs.
The parasitic worms responsible for the disease include Wuchereria...
Elevated hemidiaphragm: Elevation of half of the diaphragm, the muscle that separates the chest cavity from the abdomen and that serves as the main muscle of respiration. The elevation of a
hemidiaphragm is a significant sign of a problem.
That problem may lie below, within or above the diaphragm:
Eleventh cranial nerve
Eleventh cranial nerve: The eleventh cranial nerve is the accessory nerve. The twelve cranial nerves, the accessory nerve included, emerge from or enter the skull (the cranium) as opposed to the spinal nerves which emerge from the vertebral column.
