title: [Cholinergic and adrenergic innervation of the arteries of the base of the brain in certain lower vertebrates].
abstract: The arteries in the encephalon base have been investigated by Koelle's and Falck's methods in Teleostei (Anarhichas lupus, Eleginus navaga, Leuciscus brandti, Pelingas), amphibians (Rana temporaria, Rana semiplicata, Bufo bufo) and in reptiles (Testudo horsfieldi, Trionyx chinensis). Cholin- and adrenergic nerve fibres of the encephalic arteries have been revealed in all the vertebrates studied, but their concentration is far from being equal. In fishes and reptiles neural conductors from scarse plexus with wide loops. Concentration of effector neural fibres only in Bufo bufo exceeds that of fishes. In some cases, the arteries of frogs have equal or less density of cholin- and adrenergic neural conductors as compared with those of Pelingas. Certain individual peculiarities are noted in distribution of the effector neural fibres of the encephalic arteries of the vertebrates. In reptiles, the neural apparatus of the encephalic blood vessels reaches a considerable development; it is definitely differentiated into two plexuses - superficial and deep, having a close interconnection. The development of the effector vascular plexus in vertebrates corresponds to increasing mass of the brain and the vascular diameters. Taking into consideration structural peculiarities of the neural conductors and their concentration, it should be recognized that the role of the neural factor in regulation of the cerebral circulation increases in the following order: fishes - amphibians - reptiles.
