GU Lady Parts Flashcards
What are the organs of the female reproductive system
Includes the ovaries, the uterine tubes, the uterus, vagina, and external organs which are collectively called the vulva
What is another name for the vulva
The pudendum
What is another name for the uterine tubes
The fallopian tubes or oviducts
What are also considered part of the female reproductive system
The mammary glands
What produces secondary oocytes and hormones such as estrogen, progesterone, inhibit and relaxin
The ovaries (egg receptacles)
What are secondary oocytes
Cells that develop into mature ova or eggs
What is germinal epithelium
A layer of simple epithelium (low cuboidal or squamous) that covers the surface of the ovary
Each ovarian follicle (folliculus little bag) consist of what
An oocyte and a variable number of surrounding cells that nourish the developing oocyte and begin to secrete estrogens as the follicle grows larger
The follicle enlarges until when
It is a mature (graafian) follicle,a large, fluid-filled follicle that is preparing to rupture and expel a secondary oocyte
The remnants of the ovulated follicle develops into what
A corpus luteum
What does the corpus luteum (yellow body) produce
Produces progesterone, estrogens, relaxin and inhibit until it degenerates and turns into fibrous tissue called CORPUS ALBICANS (white body)
The ovarian medulla is a region deep to the ovarian cortex that consists of what
Loose connective tissue and contains blood vessels, lymphatic vessels and nerves
Where is the usual site of fertilization of a secondary oocyte by a sperm cell
In the uterine tube
Fertilization may occur any time up to about how long
24 hours after ovulation
The fertilized ovum is also known as what
Zygote
The zygote descends into the uterus within how long
Wishing 7 days.
Underutilized secondary oocytes disintegrate
Parts of the uterus include the dome shaped portion superior to to the uterine tubes called what
The fundus
The tapering central portion called the body
The narrow portion opening into the vagina called the cervix
What is the interior of the body of the uterus called
The uterine cavity
What is the myometrium
The middle muscular layer of the uterus which consists of smooth muscle and forms the bulk of the uterine wall
During childbirth, coordinated contractions of uterine muscles help expel what
The fetus
What is the endometrium
The inner most part of the uterine wall and is a mucous membrane. It nourishes a growing fetus or sheds monthly during menstruation if fertilization does not occur.
What is the receptacle for the penis during sexual intercourse, the outlet for menstrual flow and is the passageway for childbirth
The vagina
What is an elevation of adipose tissue covered by coarse pubic hair, which cushions the pubic symphysis
The mons pubis
What does the labia majora contain
Adipose tissue and sebaceous (oil) and sudoriferous (sweat) glands
What does NOT contain pubic hair or fat and have few sudoriferous (sweat) glands
The labia minora; which DOES contain numerous sebaceous (oil) glands
What are mammary glands
Modified sudoriferous (sweat) glands that produce milk - located in the breasts
Each mammary gland consist of how many lobes
15-20 lobes - arranged radially and separated by adipose tissue and strands of connective tissue
What are the strands of connective tissue in the mammary glands called
Suspensions ligaments of the breast (Cooper’s ligaments), which support the breast
What hormone largely stimulates milk production
Prolactin (from the anterior pituitary)
The ejection of milk is stimulated by what
Oxytocin (released from the posterior pituitary)
What is oogenesis
The formation and development of gametes in females
What is secreted by the hypothalamus and controls the ovarian and uterine cycles
Gonadotropin-releasing hormone (GnRH)
What does GnRH stimulate the release of
Follicle stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.
What initiates follicular growth and the secretion of estrogens by the growing follicles
FSH
What stimulates the further development of ovarian follicles and their full secretion of estrogens
LH
What is the duration of the female reproductive cycle
24 to 36 days (we assume duration of 28 days)
What are the phases of the female reproductive cycle (in order)
Menstrual phase
The pre-ovulatory phase
Ovulation
Post-ovulatory phase
What occurs during the menstrual phase in the ovaries
Several ovarian follicles grow and enlarge
What events take place in the uterus during the menstrual phase
Menstrual flow from the uterus consists of 50 ml -150 ml of blood and tissue cells from the endometrium
What is the pre-ovulatory phase
The time between the end of menstruation and ovulation
What is the time frame of the pre-ovulatory phase
It lasts from days 6 to 13 in a 28 day cycle
What events take place in the ovaries during the pre-ovulatory phase
Under the influence of FSH, several follicles continue to grow and begin to secrete estrogens and inhibin; by about day 6, a single follicle in one of the two ovaries has outgrown all the others to become the dominant follicle
What events occur in the uterus during the pre-ovulatory phase
Estrogens liberated into the blood by growing ovarian follicles stimulate the repair of the endometrium
What is ovulation
The rupture of the mature (graafin) follicle and the release of the secondary oocyte into the pelvic cavity
When does ovulation typically occur
On day 14 in a 28 day cycle
What is the post-ovulatory phase
The time between ovulation and onset of the next menstruation
What phase is the most constant in duration and lasts for 14 days (from day 15 to day 28 in a 28 day cycle)
Post-ovulatory phase
Stimulated by LH, the remaining follicular cells enlarge and form what
The corpus luteum - which secretes progesterone, estrogen, inhibin, and relaxin
With reference to the ovarian cycle, this phase is also called the literal phase
