What's the difference between electrotonus and muscle?
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:
(1) In addition, transfer of synaptic charge in the model neuron, under both current- and voltage-clamp conditions, equalled theoretical predictions from two-port analyses of linear electrotonus.
(2) High-density recordings (2 mm) along the arc of block showed double potentials separated by an isoelectric interval, interpreted as local activation and electrotonus due to activation on the opposite side of the arc.
(3) A method to apply anodal electrotonus during the cavity preparation in labiocervical cavities was presented.
(4) In order to evaluate quantitatively these data and the hypotheses of neuronal function to which they lead, we have developed LADDER, a computer program for simulating neuronal electrotonus under current- or voltage-clamp conditions.
(5) From the different effects of the blocking agents on the fast and slow components of electrotonus, it was deduced (a) that the inward rectification is a property of the internodal axon, (b) that the slow outward rectifier is present at the nodes, and probably the internodes as well, and (c) that the 4AP-sensitive channels have a minor nodal and a major internodal representation.
(6) Different gap junctions were used for charge flow for longitudinal versus transverse electrotonus.
(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.
(10) The core conductor model, on which most previous work on cylindrical electrotonus has been based, gives rise to a one dimensional diffusion equation, the cable equation, for the transmembrane potential in a small cylinder.
(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.
Muscle
Definition:
(n.) An organ which, by its contraction, produces motion.
(n.) The contractile tissue of which muscles are largely made up.
(n.) Muscular strength or development; as, to show one's muscle by lifting a heavy weight.
(n.) See Mussel.
Example Sentences:
(1) The extents of phospholipid hydrolysis were relatively low in brain homogenates, synaptic plasma membranes and heart ventricular muscle.
(2) It was found that the skeletal muscle enzyme of the chick embryo is independent of the presence of creatine and consequently is another constitutive enzyme like the creatine kinase of the early embryonic chick heart.
(3) These immunocytochemical studies clearly demonstrated that cells encountered within the fibrous intimal thickening in the vein graft were inevitably smooth muscle cell in origin.
(4) We have amended and added to Fabian's tables giving a functional assessment of individual masticatory muscles.
(5) 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.
(6) Muscle weakness and atrophy were most marked in the distal parts of the legs, especially in the gastrocnemius and soleus muscles, and then spread to the thighs and gluteal muscles.
(7) No monosynaptic connexions were found between anterodorsal and posteroventral muscles except between the muscles innervated by the peroneal and the tibial nerve.
(8) Thus adrenaline, via pre- and post-junctional adrenoceptors, may contribute to enhanced vascular smooth muscle contraction, which most likely is sensitized by the elevated intracellular calcium concentration.
(9) In addition to their involvement in thrombosis, activated platelets release growth factors, most notably a platelet-derived growth factor (PDGF) which may be the principal mediator of smooth muscle cell migration from the media into the intima and of smooth muscle cell proliferation in the intima as well as of vasoconstriction.
(10) Further, the maximal increase in force of contraction was measured using papillary muscle strips from some of these patients.
(11) Peripheral eosinocytes increased by 10%, and tests for HBsAg, antiHBs, antimitochondrial antibody and anti-smooth muscle antibody were all negative.
(12) When subjects centered themselves actively, or additionally, contracted trunk flexor or extensor muscles to predetermined levels of activity, no increase in trunk positioning accuracy was found.
(13) A definite relationship between intelligence level and the type of muscle disease was found.
(14) After vascular injury, smooth muscle cells proliferate, reaching a maximum rate at day 2.
(15) In the absence of an authentic target for the MASH proteins, we examined their DNA binding and transcriptional regulatory activity by using a binding site (the E box) from the muscle creatine kinase (MCK) gene, a target of MyoD.
(16) Only the approximately 2.7 kb mRNA species was visualized in Northern blots of total cellular and poly(A+) RNA isolated from cardiac ventricular muscle.
(17) The variation of the activity of the peptidase with pH in the presence of various inhibitors was investigated in both control and insulted muscle fibres.
(18) Recent studies have shown that an aberration in platelet-derived growth factor gene expression is unlikely to be a factor in proliferation of smooth-muscle cells.
(19) This sling was constructed bu freeing the insertion of the pubococcygeus and the ileococcygeus muscles from the coccyx.
(20) Their effects on various lipid fractions, viz., triglycerides (TG), phospholipids, free cholesterol, and esterified cholesterol, were studied in liver, plasma, gonads, and muscle.
