• myofibril
• troponin
• actin

What structure is similar to the endoplasmic reticulum

• Golgi apparatus
• Mitochondria
• Lysosome
• Nucleus

Dark bands are made from

Muscle Twitch is the response to a single action potential from a motor neuron:

• True

• False

The delay in time where the action potential reaches muscle before tension is observed is:

• Threshold stimulus

• Relaxation Phase

• Contraction Phase

• Latent Period

Wave Stimulation is:

• Increasing of stimulus frequency

• Number of motor units during a contraction

• The rate that stimulate voltage pulses are applied to an isolated skeletal muscle

• muscle fibers that relax and no longer maintain tension

The rate that stimulate voltage pulses are applied to an isolated skeletal muscle:
