“…6,10,11). They display an infolded nucleus with abundant euchromatin and are located in the basal cell region (Herrlinger, 1970;Stanka et al, 1964). The cell body presents a clear zonation; the following cytoplasmic regions may be recognized: perinuclear, intermediate, subapical, and apical.…”

“…This hypothesis was confirmed by ultrastructural studies (Murakami & Tanizaki, 1963;Schmidt & D'Agostino, 1966;Oksche, 1969;Rodriguez 1970 a, b;Kimble & Mollgard, 1973;Wakahara, 1974;Tulsi, 1983). Other studies have not confirmed a basal route of secretion (Stanka et al, 1964;Isomaki et al, 1965;Muller & Sterba, 1965;Sterba, 1969).…”

This study concerns the subcommissural organ (SCO) of Podarcis s. sicula Raf. in normal and experimentally treated animals. SCO cells present a secretory cycle during the year, with maximum secretion in summer and minimum in winter. SCO secretory activity parallels the sexual cycle in this lizard. The secretory activity of this organ is influenced by all experimental procedures that affect Leydig cells and the SCO. Experimental evidence suggests a relationship between the SCO and the adrenal gland. Indeed, there is an increase in the secretory material of SCO cells with treatment that induces an increase of testosterone or adrenal gland activity in the organism. Vice versa, treatment that leads to a decrease in hormones or that blocks their effects, also brings about a decrease in the amount of secretory material in the SCO.All the data obtained show that both steroid hormones and thermic factors are involved in the control of SCO secretory activity.

“…The ultrastructure of secretory ependymal cells constituting the subcommissural organ (SCO) which is situated on the roof of the third cerebral ventricle below the posterior commissure has recently been studied in fishes (AFZELIUS and OLSSON, 1957;MURAKAMI and TANIZAKI, 1966;STERBA, MULLER and NAUMANN, 1967;STANKA, 1967;ALTNER, 1968), amphibians (MURAKAMI and TANIZAKI, 1963;ALTNER, 1968), reptiles (MURAKAMI, 1959;MURAKAMI, KUSABA and YAMAKAWA, 1962) and mammals (ANDERSON, 1961;LIN and DUNCAN, 1961;WETZSTEIN, SCHWINK and STANKA, 1963;NAUMANN and VOLFE, 1963;LAATSCH, 1964;STANKA, WETZSTEIN and SCHWINK, 1964;ISOMAKI, KIVALO and TALANTI, 1965;HERRINGER, SCHWINK and WETZSTEIN, 1967;VIGH et al, 1967;BARLOW, AGOSTINO and CANCILLA, 1967;PAPACHARALAMPOUS, SCHWINK and WETZSTEIN, 1968;IMAIZUMI, 1968).…”
