The motivation hypothesis was a competing hypothesis of the anti-exhaustion hypothesis. First, the responses were not corrected for the non- linear relation between transmitter release and e.j.p, amplitude (Martin, 1955). Misler S, Hurlbut WP. No physiologic or pharmacologic interpretation is offered for either constant. We desired to explore whether the constants are properties of the muscle or the MR and to simulate NMB when the MR binds to two sites at a . explanatory variable) ? Alternative therapies, such as Tai Chi (TC), have recently gained popularity as a treatment for balance impairment. The primary outcome was a composite of respiratory complications (failure . The notion of the Poisson hypothesis is extended so as to allow for nonstationarity in the data, since nonstationarity is commonly seen in the occurrence of spontaneous miniature potentials. The amplitude distribution of quanta recorded extracellularly from a single release site did not fit the compound Poisson hypothesis in two thirds of the data sets. The injured mechanoreceptors generate corrupted transducer signals, which lead to corrupted muscle response pattern produced by the neuromuscular control unit. Iontophoresis is an interesting technique that can be used to further test the hypothesis that ACh is the neurotransmitter substance at the neuromuscular junction. 1.) NEUROMUSCULAR JUNCTION A neuromuscular junction thus consists of: •Presynaptic terminal (Nerve fibre) with vesicles containing the NT •A synaptic cleft (20-30 nm wide): which is a synaptic trough or gutter.
