Muscle contraction

Explain how a slight (but smooth) contraction differs from a vigorous contraction of the same muscle; use the concepts of multiple motor unit summation.

Excitation-contraction coupling

Explain what is meant by the term excitation-contraction coupling?

Muscle fatigue

Describe the cause(s) of muscle fatigue and define this term clearly

Contractile force/velocity and duration of contraction

Name four factors that influence contractile force and two that influence velocity and duration of contraction.

Smooth muscle properties

Smooth muscle has some unique properties, such as low energy usage, ability to maintain contraction over long periods, and the stress-relaxation response. Tie these properties to the function of smooth muscle in the body.
