Порівняльна характеристика комплексу вестибулярних ядер деяких комахоїдних і рукокрилих

Abstract

Досліджені ядра вестибулярного комплексу деяких комахоїдних та рукокрилих.

Nuclei of Vestibular Complex of Insectivora and Chiroptera respesentatives have been investigated. A comparative analysis has been made proceeding from the following characters: sizes and form of vestibular nuclei, sizes, shape, staining intensity of cells composing the nuclei; the number of cells per the area unit in various nuclei relative sizes of cells and their nuclei; total relative volume of nuclei of vestibular complex in relation to the total weight of brain. It is established that the total relative volume of vestibular complex nuclei in Chiroptera representatives is at an average 2,6 — 3,0 times as high as that of Insectivora representatives. Such an exceeding is especially characteristic of the medial and lateral vestibular nuclei. High cell density was registered in all the nuclei of Chiroptera representatives. Data obtained evidence for the better development of vestibular complex in Chiroptera as compared to Insectivora.
