Minamata disease was first discovered in Japan in 1956. It was caused by the release of mercury in the industrial wastewater from a chemical factory. This high-
ly toxic chemical was found in shellfish and fish in Minamata Bay and the Shiranui Sea,

which when eaten by the local populace resulted in deaths due to mercury poison-
ing. Which of the ff. events took place?

If a grape were placed in a hypertonic solution what would happen and why?

Choose the incorrect statement (a) the motor end plate membrane is only capable of generating graded potentials, but it is contiguous with the skeletal muscle sarcolemma, which can generate action potentials. (b) propagation of an action potential through the t-tubules into the sarcoplasmic reticulum triggers the release of ca++ into the cytoplasm of a skeletal muscle fiber. (c) the generation of suprathreshold endplate potentials in multiple muscle fibers could be due to the increased frequency of action potential generation at the axon hillock of a single motor neuron. (d) a greater amount of ach would be found in the presynaptic vesicles of a motor unit that fired several action potentials after exposure to botulinum toxin, than in a motor unit that fired several action potentials after exposure to the venom of the krait snake (which contains α-bungarotoxin).
