Question

Enlist six properties of nerve fibres.​

Answer 1

 Excitability  Conductivity  Unfatigability  Refractive period  All or none response  Summation  Accommodation.

 Refractive period:  during action potential the excitability of a nerve become reduced  i.e a new impulse cannot be generated during a AP 

Answer 2

Excitability - polarized nerve fibre has ability to perceive stimulus and enter into state of action.

Conductivity - it is ability to transmit the excitation.

Summation effect - many weak stimuli in quick succession may produce a effect.
