What's the difference between electrotonus and nerve?
Electrotonus
Definition:
(n.) The modified condition of a nerve, when a constant current of electricity passes through any part of it. See Anelectrotonus, and Catelectrotonus.
Example Sentences:

(7) Electrograms recorded in proximity to the arc of block were comprised of two deflections: a local activation potential and an electrotonic potential reflecting activation 1 mm away; the reverse order of activation and electrotonus was observed on the opposite side of the arc of block.
(8) THE THEORY OF ELECTROTONUS, WHICH HAS BEEN WELL DEVELOPED FOR SMALL CYLINDERS, IS EXTENDED: the fundamental potential equations for a membrane of arbitrary shape are derived, and solutions are found for cylindrical and spherical geometries.
(9) During sustained reentrant activation, high-density recordings along the arcs of block showed split electrograms comprised of local activation and electrotonus, which were identical in morphology to those recorded during the initiation of reentry.

(11) Charging or discharging electrotonus of the preganglionic fibers were found to be slow.
(12) The suggested model allows synthetizing a variety of models of branching axons and dendrites, that promotes the possibilities of model investigation of electrotonus, propagated excitation and their interactions.
(13) The amount of the electrotonus through a separate different electrode was determined to the maximum allowable current which ranged between 0.1 and 1.5 mA.
Nerve
Definition:
(n.) One of the whitish and elastic bundles of fibers, with the accompanying tissues, which transmit nervous impulses between nerve centers and various parts of the animal body.
(n.) A sinew or a tendon.
(n.) Physical force or steadiness; muscular power and control; constitutional vigor.
(n.) Steadiness and firmness of mind; self-command in personal danger, or under suffering; unshaken courage and endurance; coolness; pluck; resolution.
(n.) Audacity; assurance.
(n.) One of the principal fibrovascular bundles or ribs of a leaf, especially when these extend straight from the base or the midrib of the leaf.
(n.) One of the nervures, or veins, in the wings of insects.
(v. t.) To give strength or vigor to; to supply with force; as, fear nerved his arm.
Example Sentences:
(1) Such a signal must be due to a small ferromagnetic crystal formed when the nerve is subjected to pressure, such as that due to mechanical injury.
(2) They are going to all destinations.” Supplies are running thin and aftershocks have strained nerves in the city.
(3) Elements in the skin therefore seemed to enhance nerve regeneration and function.
(4) The possibility that the ventral nerve photoreceptor cells serve a neurosecretory function in the adult Limulus is discussed.
(5) Following central retinal artery ligation, infarction of the retinal ganglion cells was reflected by a 97 per cent reduction in the radioactively labeled protein within the optic nerve.
(6) During the performance of propulsive waves of the oesophagus the implanted vagus nerve caused clonic to tetanic contractions of the sternohyoid muscle, thus proving the oesophagomotor genesis of the reinnervating nerve fibres.
(7) The oral nerve endings of the palate, the buccal mucosa and the periodontal ligament of the cat canine were characterized by the presence of a cellular envelope which is the final form of the Henle sheath.
(8) Sixteen patients were operated on for lumbar pain and pain radiating into the sciatic nerve distribution.
(9) The dependence of fluorescence polarization of stained nerve fibres on the angle between the fibre axis and electrical vector of exciting light (azimuth characteristics) has been considered.
(10) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
(11) Histological studies of nerves 2 years following irradiation demonstrated loss of axons and myelin, with a corresponding increase in endoneurial, perineurial, and epineurial connective tissue.
(12) The ATP content of the cholinergic electromotor nerves of Torpedo marmorata has been measured.
(13) Plasma NPY correlated better with plasma norepinephrine than with epinephrine, indicating its origin from sympathetic nerve terminals.
(14) Based on several previous studies, which demonstrated that sorbitol accumulation in human red blood cells (RBCs) was a function of ambient glucose concentrations, either in vitro or in vivo, our investigations were conducted to determine if RBC sorbitol accumulation would correlate with sorbitol accumulation in lens and nerve tissue of diabetic rats; the effect of sorbinil in reducing sorbitol levels in lens and nerve tissue of diabetic rats would be reflected by changes in RBC sorbitol; and sorbinil would reduce RBC sorbitol in diabetic man.
(15) Standard nerve conduction techniques using constant measured distances were applied to evaluate the median, ulnar and radial nerves.
