The Muscular System: Contraction of Whole Muscle

1. Treppe 2. incomplete tetanus 3.Complete tetanus 4. Fatigue

List the 5 stages of temporal summation in the correct order

fatigue

w/continued rapid stimulation muscle is no longer able to sustain its level of tension

A. Sarcomeres shorten- contraction B. Sarcomeres return to resting length- relaxation C. Sarcomeres at resting length - latent

Identify the three phases of a muscle twitch from the following definitions:

decrease

In temporal summation, you must __ ____the time interval between stimuli.

stimulating the muscle rapidly so that one contraction is not finished when another begins

Temporal summation results from:

muscle twitch

The development of tension in a muscle, in response to a stimulus above threshold, is called a

Single muscle fiber

What will contract in an all or none fashion?

.Treppe

even though the strength of contraction increased relaxation was complete

incomplete tetanus

with increased frequency of stimulation, muscle exhibits shorter contraction-relaxation cycles

complete tetanus

with rapid multiple stimulation contractions fuse into smooth continuous total contraction without evidence of cyclical
