Concept explainers
To review:
Match the follicle stage with the correct description.
The follicle stages are :
Primordial follicle
Primary follicle
Secondary follicle
Vesicular follicle
Corpus luteum
Corpus albicans
The definitions are :
a. Several layers of granulosa cells with pockets of follicular fluid surround the primary oocyte.
b. Knot of whitish scar tissue.
c. Yellow glandular-looking endocrine structure.
d. A single layer of squamous follicular cells surrounds the primary oocyte.
e. One or two layers of cuboidal granulosa cells surround the primary oocyte.
f. Several layers of granulosa cells surround the secondary oocyte and project into the antrum.
Introduction:
The primary oocyte is formed from oogonia and gives rise to ova by a process known as oogenesis. The process of oogenesis takes place in the ovaries. It begins even before the female infant is born and continues till menopause. The oocyte is always present inside the ovarian follicle. The seven stages of follicle during oogenesis are primordial follicle, primary follicle, secondary follicle, vesicular follicle, ruptured follicle, corpus luteum, and corpus albicans.
