Female Reproductive System
Card Set Information
Female Reproductive System
Lining of the uterus
Muscular layer of theuterus
Pathway along which an egg travels from the time of its release to its implantation
Ligament hepling to anchor the uterus
Structure producing female hormones and gametes
Homologue of the male scrotum
The lablum minus and the lablum majus
Chamber that houses the devolping fetus
Canal that recieves the penis during sexual intercourse
Usual site of fertilization
Erects during sexual stimulation
Duct through which the ovum travels to reach the uterus
Membrane that partially closes the vaginal canal
Primary female reproductive organ
Move to create fluid currents to draw the ovulated egg into the uterine (fallopian) tube
Female duct system consists the following three:
Uterine (Fallopian) Tubes
Composed of ovarian follicles (sac-licke structures)
Each follicle consists of:
Oocyte (immature egg)
Follicular Cells (which surround the oocyte)
Contains an immature oocyte
Growing follicle with a maturing oocyte
Graafian (vesicular) follicle
This is when the egg is mature and the follicle ruptures; happens about every 28 days
Ruptured follicle is transformed into what?
Secures ovary to lateral walls of the pelvis
Attach to the uterus
A fold of peritoneum, and encloses the suspensory ligament
Receives the ovulated oocyte
Provides a site for fertilization
Attachs to the uterus
Supported and enclosed by the broad ligament
Uterine (Fallopian) tube
This is a hollow organ that is located between the urinary bladder and rectum
Name two functions of the uterus:
Receices and retains a fertilized egg
Nourishes the fertilized egg
The main portion of the uterus
The superior rounded region above where the uterine tube enters in the uterus
The narrow outlet that protrudes the vagina in the uterus
This is the inner layer of the uterus and allows for implantation of a fertilized egg as well as sloughs off if no pregnancy occurs (menses)
The middle layer of smooth mucles in the uterus wall
The outermost serous layer of the uterus
Perimetrium (visceral peritoneum)
Partially closes the vagina until it is ruptured
Extends from the cervix to exterior of the body
Located between the bladder and rectum
Serves as the birth canal
Receives the penis during sexual intercourse
Name six of the external genitalia (vulva)
Greater vestibular glands
A fatty area overlying the pubic symphysis and is covered with pubic hair after puberty
Labia majora, hair-covered skin folds
Labia minora, delicate, hair-free folds of skin
This contains erectile tissue and corresponds to the male penis
The clitoris is similar to the penis in that it is...
Hooded by a prepuce
Composed of sensitive erectile tissue
Becomes swollen with blood during sexual excitement
The total supply of eggs are present at...
The ability to release eggs begin at...
Reproductive ability ends at...
Female stem cells found in a developing fetus
Oogonia undergos what to produce primary oocytes?
Primary oocytes are surrounded by cells that form...
primary follicles in the ovary
Oogonia no longer exist by the time of...
What starts inside maturing follicle in which produces a secondary oocyte and the first polar body?
Follicle development to the stage takes about....
Ovulation of a secondary oocyte occurs with the release of... in which secondary oocyte is released
Luteinizing hormone (LH)
An X-ray examination that detects breast cancers too small to feel and is frecommed every 2 years for women between 40 and 49 years old
Central pigmented area
Protruding central area of areola
Internal structures that radiate around nipple
Located within each lobe and contain clusters of alveolar glands
Produces milk when a women is lactating
Connects alveolar glands to nipple
Modified sweat glands that are present in both seces, but only functions in females and produces milk and are also stimulated by sex hormones (mostly estrogens) to increase in size
List six secondary sex characteristics caused by estrogens:
Enlargement of accessory glands
Development of breasts
Appearance of axillary and pubic hair
Increase in fat beneath the skin, particularly in the hips and breasts
Widening and lightening of the pelvis
Onset of menses (menstrual cycle)
Progesterone does what two things?
Helps maintain pregnancy
Prepare the breasts for milk production
This hormone does not contribute to the appearance of secondary sex characteristics is produced by the corpus luteum and the production of this continues until LH diminishes in the blood
Levels of progesterone rise and increases the blood supply to the endometrium
Endometrium increases in size and readies for implantation
Regeneration of functional layer of the endometrium
Estrogen levels rise
Ovulation occurs in the ovary at the end of this stage
Functional layer of the endometrium is sloughed
Bleeding occurs for 3-5 days
By day 5, growing ovariam follicles are producing more estrogen
List the three stages of the menstrual cycle:
_____ and _____ regulate the production of the estrogens and progesterone
FSH and LH
Female cycles are about
28 days in length
Cyclic changes of the endometrium that is regulated by the cyclic production of estrogens and progesterone
Uterine (Menstrual) Cycle
Meiosis is only completed if the egg....
What is the difference between men and women sex cell size/structure?
Sperm are tiny, motile, and equipped with nutrients in seminal fluid
Egg is large, non-motile, and has nutrient reserves to nourish the embryo until implantation
What is the difference between men and women with meiosis?
Males - produces four functional sperm
Females - produces one functional ovum and three polar bodies
