Verified
The refractory period
A) is the time during which the tissue cannot respond again.
B) results in complete and incomplete tetanus.
C) is the condition in which the muscle fiber only partially relaxes between contractions.
D) is the condition in which stimuli occur so rapidly that there are no intervening relaxations.
E) is the constant tension produced by muscles for long periods of time.
Refractory Period
The period immediately following the transmission of an impulse in nerve or muscle cells during which a second impulse cannot be generated.
Tetanus
A serious bacterial infection characterized by muscle stiffness and spasms, caused by the toxin produced by Clostridium tetani.
Muscle Fiber
A single muscle cell, typically elongated and capable of contracting to produce movement or maintain posture.

Final Answer :
A
Explanation :
The refractory period refers to the time during which a nerve or muscle is incapable of responding to stimulation, typically right after being activated. This is a fundamental property of all excitable tissues in both the nervous and muscular systems, ensuring that each signal is distinct and prevents the overlap of potential responses.
