Muscle and Muscle Tissue

_______1. muscle twitch                a. many cells responding to one neuron
_______2. wave summation             b. affects the force a muscle can generate
_______3. multiple motor unit summation          c. a single contraction of intact muscle
_______4. resting length                d. recruitment
_______5. resistance                e. increasing force produced by increasing stimulus frequency
_______6. initial velocity of shortening          f. muscle length changing due to relaxation
_______7. isotonic shortening            g. caused by application of maximal stimulus
_______8. isotonic lengthening             h. weight
_______9. motor unit                i. exhibits graded response
