Production of gametes and production of hormones (oestrogen, progesterone, relaxin)

Stroma, ovarian follicles, corpus luteum, corpus albicans

One layer of squamous follicular cells surrounds a primary oocyte with a large vesicular nucleus

<p>A primordial follicle has three major components: a primary oocyte, follicular cells (a single layer of squamous cells), and a basal lamina.</p> Signup and view all the answers

<p>The basal lamina acts as a blood-follicle barrier and marks a clear boundary between the follicle and the vascularized stroma.</p> Signup and view all the answers

<p>Primordial follicles are formed during fetal life and have a single layer of squamous follicular cells, while primary follicles are slightly larger and have cuboidal granulosa cells surrounding the oocyte.</p> Signup and view all the answers

<p>The theca interna cells are well-vascularized endocrine cells that secrete androstenedione. They have receptors for luteinizing hormone.</p> Signup and view all the answers

<p>The histological features of a secondary/antral follicle include: 1) Primary oocyte, 2) Granulosa cells (stratum granulosum, cumulus oophorus, and corona radiata), 3) Antrum (fluid-filled cavity), and 4) Follicular theca (theca interna and theca externa).</p> Signup and view all the answers

<p>The features of a mature (Graafian) follicle include: 1) Secondary oocytes (germ cell/gamete), 2) Granulosa cells (membrana granulosa/stratum granulosum, cumulus oophorus, and corona radiata), 3) Antrum (a single large vesicle), and 4) Follicular theca (theca interna and theca externa).</p> Signup and view all the answers

<p>Ovulation is a hormone-stimulated process by which the oocyte is released from the ovary. It usually occurs midway through the menstrual cycle and involves the dominant follicle reaching the most developed stage of follicular growth and undergoing ovulation, while the other primary and antral follicles undergo atresia.</p> Signup and view all the answers

<p>The corpus luteum is a temporary endocrine gland in the ovarian cortex. It is formed by the transformation of granulosa cells into granulosa lutein cells, which increase greatly in size and secrete large amounts of estrogen, progesterone, and inhibin. The theca interna also transforms into theca lutein cells, which produce large amounts of progesterone and androstenedione.</p> Signup and view all the answers
