REAON:-

For a) Excitability:- Excitability is the most fundamental functional feature of neurons. Mathematical models described by Hodgkin have revealed three types of neuronal excitability based on the relationship between firing frequency and applied current intensity.

For b) Conductivity Individual neurons have two major functional properties: irritability and conductivity.

For c) Contractility The contractile tone and contraction of processes of living isolated neurons are reported. ... The hypothesis of a common origin of the contractile tone of all nervous elements as one of the principal nonelectrophysiological properties of a neuron has been put forward.

For d) Refractory period the refractory period limits the number of action potentials that a given nerve cell can produce per unit time.
