Question

A short period during which a nerve is unable to conduct nerve impulse is called as

• A. Synaptic delay
• B. Refractory period
• C. Resting potential
• D. Critical period

Answer 1

The correct option is B Refractory period

The refractory period is a period during which a nerve or muscle is incapable of responding to stimulation, immediately following a previous stimulation. In an absolute refractory period, there is a total inability to respond, in a relative refractory period, there is a response to very large stimuli. So, the correct answer is option B.
