Myosin Actin Calcium sliding filament theory Synapse dendrite cell body axon Neurotransmitter sarcomere motor end plate cardiac muscle Skeletal muscle ATP striated sarcoplasmic reticulum ECG voluntary involuntary The type of muscle to be tested in this lab: , which is defined as being and . is defined as being both striated and . The is made up of alternating layers of myosin and actin. The motor neuron is composed of an , and the . The space between the axon and the muscle fiber is called the , and it is the site where is released to the , which eventually results in an end plate electrical potential and possible an action potential. The mechanism of skeletal muscle contraction is referred to as the . An electrical record of a muscle contraction is called an . In a relaxed skeletal muscle calcium ions are stored in the . The result of an action potential is the release of inside the muscle filament. The binding of to troponin removes it from the binding site, allowing for the thin filament, to attach. In order for the actin to disengage from the myosin filament, the energy from a molecule of must be used. • Show less
