     La sécrétion continue de FSH induit la multiplication des cellules folliculaires, qui se stratifient et forment la granulosa autour de l’ovocyte en croissance, main en restent séparées par une couche matériel glycoprotéique éosinophile (PAS positif) (Fig 17.19a). Cette couche, la zone pellucide, est traversée par des microvillosités ovocytaires et par des prolongements cytoplasmiques fins de la couche interne des cellules de la granulosa. [boldface in original]

     Continuing FSH secretion then induces the granulosa cells to divide to produce a multilayered surround to ^[sic] the enlarging oocyte, while a distinct glycoprotein layer of eosinophilic (PAS-positive) material forms between the oocyte and these cells (Fig. 17.19a). This layer is called the zona pellucida and is traversed by microvilli protruding outwards from the oocyte and by thin cytoplasmic processes from the inner layer of the granulosa cells.

Usage notes

• Like its English counterparts, and like technical names for many anatomical structures, zone pellucide is most commonly used in the singular, and with the definite article, as in the above quotation.
