please answer 6 7 8 6. Which of the following statements are correct regarding the structure and function of the neuromuscular junction? - a) The axon of each motor neuron divides as it enters the muscle with each of the axonal endings forming a neuromuscular junction with a single muscle fiber. - b) Membranes of axonal endings and the sarcolemma of the muscle fiber do not touch but are separated by a synaptic cleft. - c) Neurotransmitter molecules are stored in the axonal endings in membrane-bound synaptic vesicles. - d) Initiation of an action potential in the muscle cell membrane is the result of depolarization of the sarcolemma due to opening of Na+ channels and Na+ entering the cell. - e) All of the above (a, b, c, and d) are correct.7. During muscle activity, the fastest way of regenerating ATP is: - a) Anaerobic glycolysis - b) Direct phosphorylation via a coupled reaction of creatine phosphate and ADP - c) Aerobic respiration (oxidative phosphorylation) - d) New synthesis of ADP8. Which of the following statements is correct with regard to smooth muscle but not skeletal muscle? - a) Smooth muscle cells are capable of undergoing hyperplasia (increase in cell numbers by cell division) while skeletal muscle cells are post-mitotic and do not divide. - b) Both smooth and skeletal muscle is under voluntary control by the nervous system. - c) Smooth muscle and skeletal muscle are not composed of individual cells but the cells fuse to form a multinucleate syncytium. - d) All of the above (a, b, c, and d) are correct.
