Laboratory Exercise # 2 Skeletal Muscle Mechanics 1. What is a skeletal muscle fiber? Present (and explain) a diagram that demonstrates the interaction between actin and myosin during contraction. What is the role of calcium‚ troponin‚ and tropomyosin? 2. Present the basic anatomy of a motor neuron input into skeletal muscle. How is each muscle fiber innervated? What is a motor unit? What are the advantages/disadvantages of large and small motor units? What kinds of

The series of events prompting muscle contraction is started some place in the central nervous system‚ either as willful action from the brain or as reflex action from the spinal cord. Beginning with depolarization at the neuromuscular junction‚ the depolarizing impulse discharges acetylcholine from the nerve ending. Which then diffuses over the neuromuscular junction (a chemical synapse formed by the contact between a motor neuron and a muscle fiber). At the motor end plate‚ the acetylcholine joins
