title: [Experimental studies of the localization of neural centers in the ovaries and fallopian tubes in cows].
abstract: For the studies 4 sexually mature cows were used, in which ovaria and oviducts were cut out bilaterally or unilaterally. The fourth cow was the control of the experiment. The operated animals were kept alive for 21 days and then slaughtered. For studies were taken: the brain stem, spinal cord from the segments Th9 - Th13 and L1 - S4, bilateral spinal ganglions, bilaterally the sympathetic chain from the segment Th10 - S4, and also ganglions and visceral-plexi, anterior mesenteric, intermesenteric, posterior mesenteric, hypogastric and pelvic. The material was fixed in alcohol, embedded in paraffin and cut into 15 micron sections. The sections were stained by Nissel's method. For examinations subsequent sections were taken. Due to the operations performed degeneration changes occurred in nervous cells in the central and peripheral nervous system. They were the basis for determination of the localization of the nervous centres for ovarium and oviduct. The source of preganglionic sympathetic visceromotor fibres for these organs is nucleus intermediolateralis in the segment L2 - L3. The sympathetic postganglionic fibres originate from cells of the sympathetic chain from L1 to L3 and from the posterior mesenteric ganglion and hypogastric plexus. The source of parasympathetic fibres for ovarium and oviduct are cells of nucleus parasympathicus nervi vagi in the segment located somewhat posteriorly from obex. The source of viscerosensory fibres for the discussed parts of the sexual organs in the cow are cells of the spinal ganglions in the segment Th9 - Th13 and cells of nucleus tractus spinocerebellaris dorsalis localized in neuromers L2 and L3.
