Adrenergic nerves in organs of the reproductive system of sexually immature pigs.
The experiments were performed on 5 immature pigs weighing 32-35 kg. The ovaries and segments of the fallopian tube and uterus were collected and then cut by means of the freezing microtome. The adrenergic nerves were detected according to Thorre and Sorgeon's (1976) glyoxylic method and examined under fluorescent microscope. The presence of adrenergic fibers of various density and distribution was recorded in all examined organs. In the ovary most fibers were connected with tunica adventitia of blood vessels in the medulla of the ovary. Intensively fluorescent nerve fibers appeared also in capsules of the growing and mature follicles. In the region of the fallopian tube and uterus, the adrenergic fibers occurred in all component strata of the walls. The muscular layer was innervated to the greatest extent. There appeared fibers connected with vessels and free-lying ones. The comparison of our investigations with other authors points to the existence of certain species differences.
