Lab 51

When a primary oocyte divides, a secondary oocyte and a ____________ are produced

first polar body

A primary oocyte is closely surrounded by epithelial cells called

follicular cells

the funnel shaped expansion at the end of a uterine tube

infundibulum

Functions of the female reproductive system

1. Produce and maintain female sex cells and hormones 2. Transport sex cells to site of fertilization 3. Provide environment for developing offspring 4. Move offspring outside

The myometrium is largely composed of

smooth muscle

The largest of the ovarian attachments is called the __________ ligament

Broad

Describe a microscope slide of the uterine wall section.

Endometrium: Inner mucosal layer Myometrium: Middle thick muscular layer Perimetrium: Outer serosal layer

Primordial follicles are stimulated to develop into primary follicles by the hormone called

FSH

Describe the function of the cilia in the lining of the uterine tube

Help move the secondary oocyte into the infundibuium of the tube and continue to move towards the uterus

The vaginal orifice is partially closed by a thin membrane called the

Hymen

What are the external structures?

Labia majora, labia minora, clitoris and vestibular glands

The rounded mass of fatty tissue overlying the pubic symphysis of a female is the

Mon pubis

Describe a microscope slide of an ovary section with maturing follicles.

Outer cortex: *composed of densely packed cells with developing follicles. *thin layer of cuboidal cells that are germinal epithelium *primordial follicles underneath ^ Inner medulla: loose connective tissue Each follicle contains a single, primary oocyte with a nucleus and covering of follicular cells.

What organ produces egg cells and female sex hormones?

Ovaries

The process by which a secondary oocyte is released from the ovary

Ovulation

The ovaries are located in the lateral wall of the _______ cavity.

Pelvic

Describe the fate of a mature follicle.

Swells and ruptures under the influence of certain hormones, as this happens the secondary oocyte (egg cell) and follicular fluid escape from the ovary.

Uterine tubes are also called oviducts or

fallopian tubes

Briefly describe the changes that occur in the uterine lining during a reproductive cycle

Uterine lining thickens and becomes granular and vascular. If fertilization does not occur, the lining degenerates creating menstral flow.

What are the internal accessory structures?

Uterine tubes, uterus and vagina

Describe a microscope slide of the cross section of a uterine tube.

Very irregular lumen because of folds of mucosa layer. Inner lining: *Simple columnar epithelium some ciliated

A portion of the uterus called the _______ extends downward into the upper portion of the vagina

cervix

The female organ that corresponds to the male penis is the

clitoris

Th inner mucosal layer of the uterus is called the

endometrium

The meiosis of egg formation is called

oogenesis

The ovarian cortex appears granular because of the presence of

ovarian follicles

A primary follicle can develop into a _________ and then into a _________ just before ovulation

pre-antral follicle and then mature antral follicle

The ___________ of the female corresponds to the Bulbourethral glands of the male

vestibular glands

The group of external accessory organs that surround the openings of the urethra and vagina comprise the

vulva
