WebAction potentials are: all-or-none; they either happen or they don't. Compared to action potentials in unmyelinated neurons, action potentials in myelinated neurons: travel much faster Nicotine mimics acetylcholine and causes the same activation. In contrast, curare blocks acetylcholine receptors. WebCurare What is the last step at the neuromuscular junction after the propagation of an action potential at the axon terminal? Acetylcholine binds with receptor sites on the muscle membrane **The summing of EPSPs from many presynaptic nerve fibers converging onto one postsynaptic neuron is called: a. spatial summation b. twitch summation

WebCurare (10 −4 M) selectively antagonised the GDN-mediated epsps (Fig. 19A) and the depolarizing response to DA, though it was not effective in all cases.ACh also produced a depolarization of the postsynaptic neurons which was blocked by curare but the DA and ACh receptors could be distinguished by hexamethonium (Fig. 19B; cf. Ascher, …
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.
