A 56-year-old man sees a specialist because of weakness in his legs that improves over the course of the day or with exercise. Extracellular electrical recordings from a single skeletal muscle fibre reveal normal miniature end-plate potentials. Low-frequency electrical stimulation of the motor neuron, however, elicits an abnormally small depolarization of the muscle fibres. The amplitude of the depolarization is increased after exercise. 83. Based on these findings, which of the following is the MOST likely cause of this patient’s leg weakness? A. Acetylcholinesterase deficiency B. Blockade of postsynaptic acetylcholine receptors C. Impaired presynaptic voltage-sensitive Ca2+ influx D. Inhibition of Ca2+ re-uptake into the sarcoplasmic reticulum E. Reduced acetylcholine synthesis 84. The molecular mechanism underlying these symptoms is MOST likely to involve which drug target? A. Receptors B. Ion channels C. Enzymes D. Tubulins E. Carrier molecules 85. The musculoskeletal condition above can be managed by which of the following drug agents? A. Ion channel modulators B. Receptor agonists C. Carrier molecules inhibitors D. Receptor antagonists E. Enzyme inhibitors
