Afferentation (Latin afferens, afferentis - bringing) is a stream of nerve impulses that enter the central nervous system from intero- and exteroreceptors. Anokhin P. K., Soviet physiologist, academician of the USSR Academy of Medical Sciences (1898-1974), proposed the following terms used to designate the types of afferentation:
Reverse afferentation - the principle of the body's functional systems, which consists in carrying out a constant assessment of a useful adaptive result by comparing its parameters with the parameters of the acceptor of the result of the action;
Environment afferentation is a component of afferent synthesis, which is the effect on the body of all external factors that make up a specific situation, against the background of which adaptive activity takes place;
Starting afferentation is a component of afferent synthesis that implements the already formed prestarting integration of excitations into a behavioral act; a conditioned stimulus belongs to the characteristic type of triggering afferentation.

Automatism (Greek automates spontaneous, self-acting) - the ability of individual cells, tissues or organs to rhythmic activity in the absence of obvious connections with external stimuli
Adaptation (lat.adaptatio - adaptation) - the process of adaptation of an organism, population or other biological system to changing conditions of existence (functioning)
Adenoma (adenoma; Greek aden - iron + Greek ōma - ending in the name of tumors) is a benign tumor arising from the glandular epithelium and retaining structural similarity with the original tissue
Adrenergic receptors (lat.adrenalis - adrenal; lat.ad- - at + ren - kidney + receptor - receiving; synonym: adrenergic receptors, adrenoreactive structures, adrenoreactive systems) - biochemical structures of cells that interact with adrenergic mediators (dopamine, adrenaline, noradrenaline ) and convert the energy of this interaction into the energy of a specific effect (muscle contraction, nerve impulse)
Acrodermatitis (acrodermatitis; Greek akros - the most distant, extreme, high + derma (dermatos) - skin + Latin it (word-form suffix) - inflammatory process) - the general name of a group of dermatoses with an exclusive or predominant lesion of the distal extremities
