The labia minora (Latin for 'smaller lips', singular: labium minus, 'smaller lip'), also known as the inner labia, inner lips, vaginal lips or nymphae are two flaps of skin on either side of the human vaginal opening in the vulva, situated between the labia majora (Latin for 'larger lips'; also called outer labia, or outer lips). Other features include the pudendal cleft, pubic hair, sebaceous glands, the vulval vestibule, and the urogenital triangle. The main structures of the vulva are: the mons pubis, the labia majora and labia minora, the external parts of the clitoris the clitoral hood and the glans, the urinary meatus, the vaginal opening and hymen, and Bartholin's and Skene's vestibular glands.

Theca interna cells express receptors for luteinizing hormone (LH) to produce androstenedione, which via a few steps, gives the granulosa the precursor for estrogen manufacturing.. After rupture of the mature ovarian follicle, the theca interna cells differentiate into the theca lutein cells of the corpus luteum.Theca lutein cells secrete androgens and progesterone. At the completion of the preantral phase of folliculogenesis, a fully grown secondary follicle contains five distinct but interacting structural units: a fully grown oocyte surrounded by a zona pellucida, approximately 9 layers of granulosa cells, a basal lamina, a theca interna, a theca externa and a capillary net in the theca tissue (Fig. Histology and embryology -examination preparation Cytology and general histology. The cumulus oophorus, (discus proligerus), is a cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation.In the antral follicle, it may be regarded as an extension of the membrana granulosa.The innermost layer of these cells is the corona radiata..
