|
Produce sperm into the seminiferous tubules |
Gonads |
|
|
What part of the brain produces FSH and LH? |
The anterior pituitary by GnRH |
|
|
Where’s does sperm mature? |
Epididymis |
|
|
Follicles |
Contain and nourish the ovum |
|
|
One oocyte is produced every |
Month |
|
|
When does meiosis II happen? |
After fertilization |
|
|
What does estrogen do? |
Thicken endometrium |
|
|
What produces progesterone and what phase is it secreted? |
Corpus luteum and in the luteal phase |
|
|
4 phases of menstrual cycle |
Follicular phase Ovulation Luteal Phase Menstruation |
|
|
Low estrogen and progesterone results in a rise in GnRH and FSH. FSH stimulates follicles to make estrogen, which triggers ovulation. |
Follicular phase |
|
|
A surge of LH from high estrogen levels. LH causes follicles to burst and release the ovum. |
Ovulation |
|
|
As LH levels drop, it’s maintains the corpus luteum. Overtime it decreases LH. |
Luteal phase |
|
|
Corpus luteum atrophied due to low LH. This causes endometrium shedding. |
Menstruation |
|
|
Sex linked genes are also said to be |
X-linked |
|
|
Seminiferous tubules produce ________ via ___________ cells |
Sperm; sertloli |
|
|
Cells of Leydig (interstitial cells) are know to secrete ___________. |
Testosterone and other hormones |
|
|
When do sperm gain their motility? |
Once it passes through the epididymis. |
|
|
Why is sperm slightly alkaline? |
It has to survive the acidic environment of the vagina during fertilization |
|
|
Cowper’s gland |
Cleans remnants of urine and lubes the urethra |
|
|
Spermatogenesis steps |
Spermatogonia——> primary spermatocyte—> secondary-> spermatids—>spermatozoan |
|
|
Progesterone and estrogen are produced in |
The ovaries |
|
|
Egg pathway |
Peritoneal sac—> Fallopian tubes (movement)—> uterus (development) —> cervix |
|
|
All women are born with primary oocytes. When is meiosis I complete? |
1 time every month during ovulation |
|
|
During ovation, where is the secondary oocyte arrested? |
Metaphase II |
|
|
During ovation, where is the secondary oocyte arrested? |
Metaphase II |
|
|
When is meiosis II completed? |
After fertilization |
|
|
What’re the two outer layers on the oocyte? |
Sons pellicida Corona radiata |
|
|
Meiosis II begins: |
Once the corona radiata is triggered by the acrosome. |
|
|
What hormone is restricted before puberty? |
GnRH |
|
|
The hypothalamus releases GnRH. What hormones does it trigger to be released and from where? |
FSH and LH via the anterior pituitary gland |
|
|
Androgens help promote: |
Sexual differentiation |
|
|
FSH is responsible for secreting which hormone? |
Estrogen |
|
|
Progesterone is secreted in response to which hormone? |
LH |
|
|
What hormone spikes to induce ovulation? |
LH |
