卵巢的神经供给

INNERVATION OF THE OVARY

卵巢的神经供给的研究,早在十九世纪的七十年代就已经开始,Frankenhauser(1867)[1]与Waldeyer(1870)[2]描述过神经纤维由卵门进入卵巢,或伴随血管,或直接到达卵泡。此后又继以许多研究。然而除了卵巢血管有丰富的神经供给为组织学家所公认以外,卵巢基质与间质里的神经结构的研究结果却很少.

In studying the microscopic preparations of the ovaries of cats and dogs impregnated with silver according to the methods of Bielschowsky-Gros and Weber.the following observations were made:1.Three kinds of sensory nerve endings were found in the ovarian stroma:the arborization type occurred most frequently,the ball-like receptor came next and the encapsulated ending was rarely found.2.Four days after the unilateral removal of the 9-11th thoracic spinal ganglia,degenerated nerve fibers were found in the nerve trunks in the ovarian stroma.These degenerated fibers showed marked granulation and vacuolation.3.The ovarian follicles were directly innervated.The nerve fiber passed into the follicle and divided repeatedly in very much complicated arborizations well demonstrated in a transparent reconstruction model.Their terminal bran-ches were mainly found in the theca folliculi;some of them passed into the mem-brana granulosa.The ultimate terminal structures were represented in fine filaments,terminal rings or enlargements,or in metaterminal apparatus.4.Direct innervation of the corpus luteum and the atrophic follicles were observed in the preparations.Nerve fibers divided into branches and terminated among the luteum cells.In the atrophic follicles,nerve terminations could be found in the innermost layer of the theca while the membrana granulosa had already undergone degeneration.
