The Apparatus in the Blood Vessels of the Hypophysis, Regulating their Blood Flow

“…Paying his attention on CH-phobe tractus tubero-infundibularis, SPATZ (1951)(1952)(1953)(1954)(1955) has presumed that this tract conveys the chemical changes of blood in primary capillary net work of the hypophysial portal veins centripetally to the center in hypothalamus, as a chemoreceptor. However, there is no histological evidence to show that this tract participate in the centripetal communication and the origin of this tract is nucleus infundibularis.…”

“…Contrary to ordinary smooth muscles to reduce the vascular lumen in diameter by their contraction, these epitheloid muscle cells are considered to have some secretory function to release acetyl choline-like substance into the circulating blood and to control apart of the function of organs. LUCKNER and STAUBESAND (1951) have revealed that the extract of the human glomus coccygeum having many epitheloid muscle cells, has a similar biological action to acetyl choline. Many nonmyelinated nerve fibers, which make fine net works in the connective tissue capsule of the vascular wall, are present in the arterio-venous anastomosis.…”
