WebNeuromuscular Junctions. Skeletal muscle cell contraction occurs after a release of calcium ions from internal stores, which is initiated by a neural signal. Each skeletal muscle fiber is controlled by a motor neuron, which conducts signals from the brain or spinal cord to the muscle. The following list presents an overview of the sequence of ... WebMuscle contraction: The activation of tightening the muscle cells results in muscular contraction. Muscle contractions are caused by calcium ions. The sarcoplasmic reticulum releases calcium ions in response to the action potential, It binds to troponin on the actin filaments and causes conformational changes that expose the myosin-binding sites. eastern ornamentals nursery and garden center
