• A)1 and 2 have the same potential
• B)2 has twice the potential of 1
• C)2 has half the potential of 1
• D)1 and 2 have the same charge
• E)all of the charge is dissipated

Definitions:

Cross-Bridges

Molecular links between actin and myosin filaments in muscle fibers that are responsible for muscle contraction.

Incomplete Tetanus

A condition where muscle fibers produce almost peak tension during rapid cycles of contraction and relaxation.

Complete Tetanus

A condition of sustained muscle contraction resulting from rapid, repetitive stimulation that does not allow for relaxation between stimuli.

Fiber Relax

A process where muscle fibres return to a state of rest and lengthen after contraction or tension.
