WebMay 28, 2009 · What is the effect of curare on eliciting an action potential? it is an alpha-toxin that binds to acetylcholine binding sites on the postsynaptic cell membrane, which prevents the... WebThe action potential would depolarize as usual, but the repolarization phase would take longer, causing the action potential to be more broad in time. (The passage of K + ions through open voltage-gated K + channels is an important component of the repolarization phase of the action potential.

WebAug 25, 2024 · Curare is specifically a non-depolarising neuromuscular blocking agent (NMBA). It blocks neuromuscular transmission - a process that allows the central nervous system (CNS) to control the movement of muscles - at the neuromuscular junction, which is the junction between a nerve cell and a muscle cell. WebJ.P.V. Heuvel, in Comprehensive Toxicology, 2010 2.03.2.1 Receptors and Chemical Selectivity. Although Claude Bernard did not talk about receptors per se, he demonstrated that the effects of a drug or toxin (in his case curare) depended on its ability to access a particular site of action, what he called a locus of drug effect. Bernard concluded from a … dairy fat vs animal fat

WebJan 10, 2024 · Both outputs come as monophasic pulses with a duration (roughly 2 milliseconds) and form similar to an action potential. The two pulses have the same simple waveform, although the high voltage has a much greater magnitude and is delivered at a much higher rate. ...
