matching

summation | complete relaxation
tetanus | no relaxation
treppe | partial relaxation

Explanation:

Analyze the physiological terms

Using the Skeletal Muscle Physiology knowledge point

• Summation (specifically wave summation) occurs when successive stimuli arrive before the muscle has relaxed completely from the prior twitch, resulting in a stronger contraction with only partial relaxation between stimuli.
• Tetanus (specifically complete or fused tetanus) occurs when the frequency of stimulation is so high that the muscle has no relaxation phase at all, remaining in a smooth, sustained contraction.
• Treppe (the staircase effect) is the phenomenon where a muscle contracts more forcefully in response to the same strength of stimulus after it has undergone complete relaxation and is stimulated again.

Match the pairs

Using the Skeletal Muscle Physiology knowledge point

• Summation matches with Partial relaxation.
• Tetanus matches with No relaxation.
• Treppe matches with Complete relaxation.

Answer:

The matching pairs are:

• Summation — Partial relaxation
• Tetanus — No relaxation
• Treppe — Complete relaxation
