A worksheet aimed at advanced biology students, this resource serves as a recap of key events that occur during muscle contraction. The worksheet includes reference to the appearance of striated muscle fibres when in a state of contraction and relaxation (e.g. I bands, A-bands, H-zone) and the sequence of events that occur at the neuromuscular junction when a nerve impuse triggers muscle contraction.
Key words: muscle, fibres, A-band, I-band, H-zone, contraction, relaxation, calcium, troponin, tropomyosin, myosin, actin
