Answer

Brief Explanations:

The axon terminals of a nerve cell and the sarcolemma of a skeletal - muscle cell join at the neuromuscular junction. Troponin and tropomyosin are regulatory proteins in myofibrils, not contractile proteins (the contractile proteins are actin and myosin).

Answer:

Question 7: D. neuromuscular junction Question 8: False
