Abstract | This chapter discusses the function of nicotinic synapses. There are at least three types of synapse, at which the primary transmitter is acetylcholine (ACh) working on postsynaptic nicotinic receptors, and they differ considerably from one another. The most thoroughly studied synapse is between motor nerve and voluntary muscle fibres. The neuro-neuronal synapsesin autonomic ganglia are discussed. Neuromuscular transmission in mammals seems to be similar physiologically to that in frogs, and the recent use of single channel recording to study the equilibrium concentration-response relationship of rat endplate nicotinic receptors are similar to those of the frog. Both seem to have a low affinity for ACh in the resting state, and for both, the equilibrium between open and shut states for fully liganded channels is well over toward the open side. It seems that neuronal nicotinic receptors, like neuronal GABA and glutamate receptors are more complex than muscle-type receptors. |
