Fig. 4 — Effect of geraniol treatment on Hippocampal histopathological alternations in all the studied groups; I Control group, II geraniol group, III d-galactose group, IV D-galactose + geraniol group. Po: polymorphic layer; P: pyramidal layer; M: molecular layer; arrows: represent pyramidal cells with rounded nuclei with prominent nucleoli and basophilic cytoplasm in (I, II) but represent pyramidal cells with pyknotic nuclei and vacuolated acidophilic cytoplasm in (III, IV); arrow heads: apical dendrites extending to molecular layer in (I) but they represent pyramidal cells with fragmented nuclei in (III); wavy arrows: scattered neuroglial cells; V: scattered small blood vessels; curved arrows: represent pyramidal cells with ill-defined nuclei in (III); Tailed arrows: represent corkscrew dendrites of some pyramidal cells in the molecular layer in (III) (H&E. X 400, scale bar = 50 μm)
