The ultrastructure of the oviduct and the hormonal induced
alterations in the cellular organelles of prepubertal and ovariectomized
rabbits have been studied with electron-microscopic histochemical
methods.
The pseudostratified epithelium of the oviduct in prepubertal
rabbits contained both ciliated and secretory cells. The secretory
cells showed apocrine projections filled with electron-dense...

choice behavior under conditions of verbal reinforcement, in a nursery
school population of both sexes. Two major hypotheses were
tested: The ordinal hypothesis stated that under conditions of increased
value of the payoff subjects' stable-state strategies will
