its antagonist is the biceps brachii.d) The rectus abdominis is on the front of the abdomen and flexes the vertebral column. 13) Which statement is NOT true of the energy sources for muscle contraction?a) Creatinine is a nitrogenous waste product formed when creatine phosphate is used for energy.b) The direct (immediate) energy source for contraction is glycogen.c) When glycogen is used for energy, it is first broken down to glucose.d) Oxygen is required for the aerobic cell respiration of glucose to produce ATP. 14) Which statement is NOT true of the neuromuscular junction?a) The axon terminal is the end of the motor neuron.b) Acetylcholine makes the sarcolemma very permeable to potassium ions.c) The sarcolemma contains cholinesterase to inactivate acetylcholine.d) The synapse is the small space between the axon terminal and the sarcolemma.  15) Which statement is NOT true of exercise?a) Increased heart rate transports oxygen to muscles more rapidly.b) Isotonic exercise is aerobic because it involves contraction with movement.c) Increased cell respiration produces more heat, ATP and carbon dioxide.d) Increased respiration is necessary to exhale excess carbon dioxide. 16) Which statement is NOT true of oxygen and muscle contraction?a) Oxygen is brought to muscle fibers by hemoglobin in red blood cells.b) Some oxygen is stored in muscles by the protein myosin.c) Oxygen is needed for the complete breakdown of glucose in cell respiration.d) In the absence of oxygen, lactic acid is formed and causes fatigue. 17) Which statement is NOT true of the sliding filament mechanism of muscle contraction?a) The sarcoplasmic reticulum releases calcium ions following depolarization.b) Myosin filaments pull actin filaments toward the center of the sarcomere.c) Troponin and tropomyosin are inhibiting proteins.d) During depolarization, the inside of the sarcolemma becomes negative. 18) Which statement is NOT true about muscle tissue?a) Both cardiac and skeletal muscles are striated.b) Skeletal muscle is voluntaryc) Smooth muscle is non-striated.d) Both cardiac and smooth muscle are voluntary. 19) Which of the following is NOT true about diarthrotic joints?a) The movement of the thumb involves a diarthrotic jointb) Diarthrotic joints have a synovial cavity in them.c) A hinge joint would be classified as a diarthrotic joint.d) Diarthrotic joints are “slightly movable”. 20) Which one of the following is NOT true about the Neuromuscular junction (NMJ)?a The inflow of potassium ions generates a muscle action potential.b A motor neuron triggers a skeletal muscle fiber to contract.c The neurotransmitter (ACh) initiates the muscle action potential.d ACh is broken down by the enzyme acetylcholinesterase.    For each of the 20 questions, identify the incorrect answer (letter, a, b, c, or d) AND reword the statement to make it correct.
