“…C lyman [6], who first studied the ultrastructure of the human oviduct, reported an 'intercellular bridge (nexus)' and a protoplasmic bridge but the membranes were not sufficient ly clear to distinguish the exact cell relationships. Our work is in agreement with that of Kushiya [17] in rabbit ampulla and D aniel et al [7] in human Fallopian tube, both of whom described separations of ca.…”

The types of cell-to-cell contacts and the relationship between the nerve endings and the smooth muscle of the estrogen-treated rabbit oviduct have been investigated. The cell contacts most consistently found in the oviduct were simple appositions, with a 20-nm cell separation, which occasionally included a more dense region, and interdigitations of muscle cell processes with the same separation distances. Very rarely, wider intermediate contacts were present. Gap junctions (nexuses) were absent. It seems likely that simple appositions and interdigitations form the low resistance pathway for conduction of electrical activity. Nerves containing small dense-cored vesicles were present both within and near muscle bundles; they were rarely found close to smooth muscle cells.

“…Extensive studies have dealt with the structural and ultrastructural characteristics of the epi thelia of the mammalian oviduct [H afez [Blandau and M o g h issi, 1973]. Based on their histological and histochemical criteria differ ent types of cells have been classified in the different regions of the oviduct [Clyman, 1966; R e in iu s, 1969; W o o d r u ff and Pauerstein, 1969] and cervix [H a fez, el al., 1971; H afez, 1973], The activity of these cells reflect the physiological activity of ovarian hormones secreted during different phases of the cycle. Structural changes that occur in the epithelia cells during the menstrual cycle and the species differences in the distribution of cell types have been described for the oviduct and cervix [Brenner, 1969; Brenner et al, Fig.…”

Histomorphology of Cervical and Uterine Epithelia of Crab-Eating Macaque, <i>Macaca fasciculari</i><i>s</i>

Cytological characteristics and pattern of distribution of different cell types in the epithelia of cervix and uterus of crab-eating macaque (Macaca fascicularis) in follicular and luteal phases of the menstrual cycle and amenorrhea were studied. The cervix uteri and uterus exhibit remarkable structural differences in the ciliated, secretory, and ciliated-secretory cells. Since the number of ciliated-secretory cells in the uterus is higher than in the cervix, it is believed that they form an additional source for the secretion of uterine fluid during the menstrual cycle. Both ciliated and secretory cells undergo degeneration ; extensive cytoplasmic vacuolation associated with pycnosis and disorganization of the nuclei are encountered.

“…Exocytosis is considered to be the mode of secretion in rabbits [14], cattle [13], and cats [9]. In the human oviduct, secretion occurs by a holocrine mode with rupture of the cell [15]. In the mid-luteal and the late luteal phases, we observed fragments of cytoplasm which were freed in the ampullar lumen.…”
