Muscle Fiber contractions for our purposes begins with the arrival of action potential (action potential- is an electrical current) at the end of the axon terminal (axon terminal- the swollen distal end of the motor neuron axon). When the action potential reaches the axon terminal the action potential causes the voltage- gated calcium ion channels to open allowing calcium to flow in from extracellular fluid. The presence of calcium in the axon terminal causes synaptic vesicles (synaptic vesicles-

Skeletal muscle moves because we want it to. It is controlled voluntarily (consciously). There is 2 types of contraction Isometric: As the muscle contracts‚ it remains the same length whilst the tension increases in an attempt to overcome the opposing force. Example: Holding a glass of water still in front of you. Isotonic: As the muscle contracts its length changes whilst the tension remains constant or develops to overcome the opposing force. Example: Lifting a glass of water to your mount and

PACs are also called skipped heartbeats because they may make you feel like your heart is stopping for a second. CAUSES Your heart has four chambers. Normally electrical signals spread across your heart and make all the chambers beat together. During a PAC‚ the upper chambers of the heart (atria) beat too
