Physiology Of Reproductive System Flashcards
Name the two Gonadotropins that lay dormant until activated by the pituitary
FSH and LH
Name the term.
Increased secretion of adrenal androgens
Adrenarche
What is the term for development of breast
Thelarche
What hormone is responsible for the growth of ducts
Esteradiol
What hormone is primarily responsible for the growth of lobules and alveoli
Progesterone
Name the term for the development of axillary and pubic hair
Pubarche
What is the first menstrual period called?
Menarche
What controls and regulates sexual maturity?
Hypothalamic, pituitary, and ovarian hormones
What is the first phase of the ovarian cycle?
Follicular phase
What hormone comes from the anterior pituitary on day one?
FSH
What does FSH do on day one of the cycle?
Stimulates several primordial follicles to enlarge
What is it called when the Oocyte is surrounding by elongated follicular cells
Corona radiata
When does the one mature follicle become dominant?
Day 6
When does the luteal phase start?
Day 14
What hormone predominates in the luteal phase?
LH
What does the luteal phase start with?
Ovulation
What is it called when the left behind follicles fill with blood?
Corpus hemmorrhagicum
What hormone is secreted if fertilization occurs?
Progesterone
What is known as the menstrual phase of the uterine cycle?
Day one of bleeding. Endometrium sheds its functional layer
What is the proliferative phase of the uterine cycle?
When menstruation ceases to ovulation.
What hormone levels increase during the proliferative phase
Estrogen from the ovaries
What is known as the secretory phase of the uterine cycle
After ovulation until next day 26
What hormone increases from the corpus luteum during the secretary phase
Progesterone
What is the premenstrual phase of the uterine cycle
The last two days if fertilization does not occur the corpus luteum atrophies and progesterone plummets
What hormone does the hypothalamus produce?
GNRH
What does GNRH stimulate to secrete what hormone?
Similes pituitary to secrete FSH
FSH simulates the ovary to produce which hormone?
Estrogen
What happens when estrogen goes back to the hypothalamus?
This decreases FSH and increases LH
What hormone is released from the ovum to initiate ovulation
The LH surge
What hormone levels fall if fertilization does not occur
Estrogen and progesterone
The suppression of FSH and LH is lifted
What happens prior to our relation information in order for easier travel of the sperm?
Estrogen acts to swell and soften the cervix and thins the cervical mucus
What is progesterone do after ovulation
Causes the cervix to harden, close, secrete thicker, more hostile mucus which acts as a plug pre-venting bacteria and sperm from entering the uterus
What happens to a woman’s temperature during the luteal phase?
It increases
