Study Notes

Follicles and Hormone Production

Primordial follicles do not contain theca interna cells.
The corpus luteum is responsible for the production of hormones such as estrogen and progesterone.
The basal lamina in follicles provides a physical barrier and regulates the passage of molecules.

Ovarian Structure and Function

The ovarian cortex is the outer region of the ovary where follicles develop.
The germinal epithelium/ovarian surface epithelium is responsible for the formation of new follicles.

Cell Types and Functions

Theca interna cells produce androgens, which are then converted to estrogens by granulosa cells.
Granulosa cells in the secondary follicle are located in three areas: antral, basal, and cumulus.
Ciliated cells in the uterine tubes help move the egg towards the uterus.
The cervical glands in the cervix produce mucus that helps facilitate sperm passage.

Menstrual Cycle and Uterine Layers

The endometrium, the innermost layer of the uterus, undergoes profound changes during the menstrual cycles.
The endometrium reaches its maximum thickness during the luteal phase.
The myometrium, the middle layer of the uterus, is composed mainly of smooth muscle.
Estrogen is responsible for inducing regeneration of the functional layer of the endometrium lost during menstruation.

Follicle Development and Characteristics

Primary follicles with a simple cuboidal epithelium around the growing oocyte are characterized as unilaminar.
The antrum is the fluid-filled cavity present in secondary follicles.

Other Key Facts

The temporary endocrine gland in the ovarian cortex is called the corpus luteum.
Luteinizing hormone plays a role in the development of primary follicles.
The vaginal epithelium is non-keratinized stratified squamous epithelium.
