title: [Structure of the sensory nerve apparatus of the branchial arteries of several representatives of bony fishes].
abstract: The innervation of bony arteries was studied in 19 fishes (6 perches, 11 breams and 2 pikes) by the silver impregnation method after Kajal--Faworski and Bielschowski--Gross. In the first branchial arc as well as in others the receptors of two kinds were revealed: those having the main type of branching and diffuse arborescent vessels. In rare cases granular terminations were revealed. The number of terminations found in the first branchial arc was twice as great as that in each of the rest arcs. A characteristic feature of the sensory nerve terminations of the branchial apparatus in fishes is their arborescent structure, a diffuse disposition of terminal branches and absence of special cells from the receptor. The structure of the receptory terminations in the first branchial arc of fishes is morphologically similar to the de Castro Ist type sensory terminations which he has found in the carotid sinus wall of mammals.
