WebThe whole process is called the mechanism of muscle contraction and it can be summarized in three steps: (1) A message travels from the nervous system to the muscular system, triggering chemical reactions. (2) The chemical reactions lead to the muscle fibers reorganizing themselves in a way that shortens the muscle--that’s the contraction. WebThe influx of calcium through the voltage-gated calcium channels initiates the exocytosis process that leads to neurotransmitter release. Calcium enters the cell and interacts with another vesicle-bound protein called synaptotagmin. This protein is a calcium sensor, and when calcium is present at the active zone, synaptotagmin interacts with ...
