Skeletal muscle is described as striated. What are the lighter, thinner stripes noted under the  microscope?  Group of answer choices troponin actin myosin dystrophin   Rather than innervating individual muscle fibers, motor neurons often innervate two or more muscle fibers. The motor neuron and the muscle fibers it innervates are together called a:  Group of answer choices motor unit myofibril muscle fascicle motor fascia   Fast glycolytic muscle fibers allow for relatively quick ATP energy production by splitting glucose (but eventually leads to fatigue), a process described as:  Group of answer choices fermentation aerobic pathway anaerobic pathway ATP reserve use
