Reproductive system Flashcards
What are 2 functions of the reproductive system
- Production of gamates/sex cells 2. Production of hormones
Both male and female reproductive tracts are mostly nonfunctional until
puberty
The release of what hormone from where stimulates puberty
gonadotropin releasing hormone from the hypothalamus
Gonadotropin releasing hormone stimulates the secretion of ___ and ____ from ______ gland which stimulates the gonads
FSH and LH from the anterior pituitary gland
Male gamate
sperm
Female gamate
egg/ ovum/ oocyte
Gamates are produced by
meiosis
Gamates are ______ cells
haploid
Male gamate production begins at
puberty
Female games are all produced
before birth and one egg matures with each menstrual cycle
Goal of meiosis is
produce genetically unique haploid daughter cells
Primary female reproductive organ
ovaries
Ovarian follicle
egg and follicular cells
What are the 4 accessory organs of the female reproductive system
- Fallopian tubes 2. Uterus 3. Vagina 4. Vulva
Ovarian follicles are housed within
the ovaries
What are the 7 stages of follicular development in females
- Primordial follicle 2. Primary follicle 3. Secondary follicle 4. Mature follicle 5. Ovulation 6. Corpus luteum 7. Corpus albicans
How long is the ovarian cycle
approximately 28 days
What are the 3 stages of the ovarian cycle
- Follicular phase 2. Ovulation 3. Luteal phase
Follicular phase is days
1-13
Ovulation is day
14
Luteal phase is days
15-28
The follicular phase is characterized by rising levels of
FSH and LH
Rising levels of FSH and LH in the follicular phase triggers
a clutch of primordial follicles to start developing
What other hormone is also increasing during the follicular phase
estrogen
Release of the oocyte form the mature follicle
ovulation
Ovulation occurs when _____ levels peak
LH
Phase when ruptured follicle cells become corpus luteum
Luteal phase
The corpus luteum secretes _____ and _____ that stabilize and build up the uterine lining
progesterone and estrogen
If the oocyte is not fertilized the corpus luteum degenerates to
corpus albicans
When the corpus albicans develops the _____ occurs
mestrual period
If the oocyte is fertilized the corpus luteum
continues to secrete hormones through the first trimester
What are the 3 phases of the uterine cycle
- Menstrual phase 2. Proliferative phase 3. Secretory phase
Menstrual phase is days
1-5
Proliferative phase is days
6-14
Secretory phase is days
15-28
Period of menstrual bleeding following steep decline in hormone levels
Menstrual phase
