Actin is the thin filament that encases, separately, the two ends of a thick myosin. The Myosin connects to the Actin through multiple symmetric ties to the outer actin. These act like rowers in a skull. These relax and tense in synchronization to contract and relax the entire muscle to which they belong. what is the stimulus for calcium to be released from the sarcoplamic reticulum? This stimulus is the from acetylcholine, a neurotransmitter, synthesized in in the cytoplasm of the motor neuron. Acetylcholine diffuses quickly across the synaptic cleft and binds to certain protein molecules. This increases membrane permeability to sodium ions. These ions enter into the muscle cell stimulates an electrical impulse. This electrical
