Abstract
The transmission of signals between cholinergic neurons and from neurons to muscle cells (neuro-neuronal and neuromuscular transduction) occurs through synapses. They are formed by the membranes of two contacting cells, presynaptic and postsynaptic, which are separated by a narrow synaptic gap. The review article provides up-to-date information about the physiological processes in cholinergic and adrenergic synapses. The role of these synapses in pharmacology and their practical significance are presented. The transmission of excitation in cholinergic synapses occurs with the help of acetylcholine. The stages of synthesis, storage and release of acetylcholine are the same in all cholinergic neurons. The specific effects of acetylcholine mediated through cholinergic synapses depend mainly on the type of synaptic cholinergic receptors. In the system of efferent innervation, adrenergic synapses are formed by the endings of postganglionic sympathetic (adrenergic) fibers and cells of effector organs.
