Detailed explanation-1: -Summation and Tetanus Contractions: Repeated twitch contractions, where the previous twitch has not relaxed completely are called a summation. If the frequency of these contractions increases to the point where maximum tension is generated and no relaxation is observed then the contraction is termed a tetanus.
Detailed explanation-2: -A muscle cramp is an involuntary contraction of a muscle that occurs suddenly and does not relax.
Detailed explanation-3: -Tetanus causes painful muscle contractions. Complete tetanus is also called fused tetanus. During complete tetanus, there’s no relaxation period between muscle contractions. Your muscle contractions completely fuse to create one continuous muscle contraction.
