What's the difference between excitable and inexcitable?
Excitable
Definition:
(a.) Capable of being excited, or roused into action; susceptible of excitement; easily stirred up, or stimulated.
Example Sentences:

(20) And that's exciting, you've got no time to slow it down.
Inexcitable
Definition:
(a.) Not susceptible of excitement; dull; lifeless; torpid.
Example Sentences:
(1) When examined using whole cell recordings, PC proved to be inexcitable in these conditions, and this inexcitability could be related to the presence of large outward K currents.
(2) At the site of administration, the terminations of gastrocnemius group Ia afferent fibres were electrically inexcitable for approximately 1 h. Subsequently, the number and excitability of these terminations appeared to be normal, as were the depolarizing actions at bicuculline-sensitive receptors of micro-electrophoretic piperidine-4-sulphonic acid and of gamma-aminobutyric acid (GABA) released at axoaxonic synapses on these terminations.
(3) Eventually, cells became inexcitable and abruptly underwent contracture.
(4) At high concentrations (greater than 20 microM), adenosine rendered nodal cells inexcitable.
(5) In the absence of NGF, PC12 cells are electrically inexcitable, while after several weeks of NGF treatment they develope Na+ action potentials.
(6) Lidocaine could normalize action potentials that were prolonged or had two stable steady states after LPC, at times retarded LPC-induced inexcitability and could render the tissue inexcitable to intracellular point stimulation but not to extracellular stimulation.
(7) The theoretical model of the AV node has the following characteristics: (1) increased vagal tone depresses excitability in the AV node, (2) depressed excitability in the AV node is inhomogeneous in both transverse and longitudinal directions, and (3) electrotonically mediated conduction occurs across inexcitable gaps in the AV node.
(8) Spectral analysis (1-1000 Hz) of spontaneous fluctuations of potential and current in small areas of squid (Loligo pealei) axon shows two forms of noise: f-1 noise occurs in both excitable and inexcitable axons with an intensity which depends upon the driving force for potassium ions.
(9) On the contrary, a passive permeability of neurons to Tl+ being similar to that of muscle cells was about 50-100 times less than a Tl+ permeability of inexcitable red cell membrane.
