Options

A. Stimuli `to` Neurotransmitter secretion `to` Relase of calcium `to` Cross-bridges formation `to` Excitation of T-system `to` Sliding of actin filament
B. Stimuli `to` Neurotransmitter secretion `to` Excitation of T-system `to` Release of `Ca^(2+)to` Cross-bridges formation `to` Sliding of actin filamemts `to` 'H' band diminishes
C. Stimuli `to` Excitation of T-system `to` Neurotransmitter secretion `to` Cross-bridges `to` 'H' band diminishes
D. `Stimuli `to` Excitation of T-system `to` Neurotranmitter secretion `to` Cross-Neurotransmitter secretion `to` Sliding of actin filaments `to` 'H' band diminishes.
