What are the two Gonadotropic hormones?

Answer 4

FSH (Follicle Stimulating Hormones) and LH (Luteinizing Hormones)

These hormones have other endocrine glands as their target

Answer 5

Tropic Hormones

Question 6

T or F: LH and FSH are gonadotropins because they stimulate the gonads. They are not necessary for life, but are essential for reproduction

Answer 6

True

Question 7

What are the three Non-Tropic hormones?

Answer 7

Prolactin, MSH, and Endorphin

Question 8

This secretes the gonadotropins

Answer 8

Anterior Pituitary Gland

Question 9

What is the only non-tropic/tropic hormone?

Answer 9

GH (Growth Hormone)

Question 10

This cycle only applies to lower vertebrates having only a small window period for ideal fertilization

Answer 10

Estrous cycle

Question 11

This cycle only applies to mammals that has a larger window period for fertilization

Answer 11

Menustral cycle

Question 12

This is the period of sexual activity that is the only time the condition of the vagina permits mating

Answer 12

Estrous

Question 13

What are the 4 stages of the Estrous Cycle?

Answer 13

1. Proestrous
2. Estrus
3. Metestrus
4. Diestrus

Question 14

This stage is where preparation of the follicle occurs

Answer 14

Proestrus

Question 15

This stage is when mating occurs (this is usually within the time range of ovulation)

Answer 15

Estrus

Question 16

This is the period of repair

Answer 16

Metestrus

Question 17

This period is where the genital area becomes small and anemic (red swelling). This also leads to pregnancy if fertilization takes place

Answer 17

Diestrus

Question 18

This is the term used when the frequency of the estrous cycle only occurs for one single EC during the breeding season

Answer 18

Monoestrous

Question 19

This is the term used for when the frequency of the estrous cycle is can happen again during the EC breeding season

Answer 19

Polyestrous

Question 20

This cycle changes what occurs in the uterus, it is also called the uterine cycle

Answer 20

Menustral Cycle

Question 21

The menustral cycle is created due to the cyclic events that occur in the ovaries, what cycle/process is this called?

Answer 21

Ovarian cycle

Question 22

Cycle (M): What does the Hypothalamus release?

Answer 22

GnRH or Gonadotropin releasing hormones

Question 23

Cycle (M): GnRH stimulates the Anterior Pituitary Gland to produce these two hormones

Answer 23

FSH and LH

Question 24

Cycle (M): FSH produces these cells

Answer 24

Sertolli Cells

Question 25

Cycle (M): The Sertolli cellls produces this negative feedback and stimulates this process for males

Answer 25

Inhibin and Stimulate spermatogenesis

Question 26

Cycle (M): The purpose of inhibit is to__?

Answer 26

Prevent the overproduction of FSH if there is too much sperm already

Question 27

Cycle (M): The LH produces these cells

Answer 27

Leydig cells

Question 28

Cycle (M): The Leydig cells produce this hormone that can act as a negative feedback to the Sertolli cells

Answer 28

Testosterone

Question 29

Cycle (M): The testosterone initiates the production of?

Answer 29

Reproductive tract and other organs

Question 30

What gonad steroids does the ovaries control?

Answer 30

Estrogen

Question 31

What gonad steroids does the testes control?

Answer 31

Testosterone

Question 32

Cycle (W): The hypothalamus produces what hormone?

Answer 32

GnRH or Gonadotropin releasing hormones

Question 33

Cycle (W): GnRH stimulates this gland to produce hormones

Answer 33

Anterior Pituitary Gland

Question 34

Cycle (W): The Anterior Pituitary Gland produces these two hormones

Answer 34

FSH and LH

Question 35

Cycle (W): FSH stimulate these cells to produce inhibin and to influence oocytes

Answer 35

Granulosa cells

Question 36

Cycle (W): The Granulosa Cells create this product and to influence ___?

Answer 36

Answer 39

Estrogen

Question 40

Cycle (W): Estrogen help stimulate these organs

Answer 40

Reproductive tract and other organs (as well as estrogen)

Question 41

Most menustral cycles take how long to complete?

Answer 41

25 to 30 days

Question 42

For younger women (15-19 and 30 years of age), how long does the Menustral cycle take?

Answer 42

30 days

Question 43

For older women such as those of the age 35 years old, how long does the menustral cycle take?

Answer 43

28 days

Question 44

This hormone stimulates the growth and development of the follicle, stimulates the secretion of estrogen and enhances effects of LH in stimulating ovulation

Answer 44

FSH or Follicle Stimulating Hormone

Question 45

This hormone stimulates the final development of the follicle, stimulates the ovulation and the development of the corpus luteum as well as the production of progesterone

Answer 45

LH or Lutenizing hormone

Question 46

This hormone stimulates the repair of the uterine lining, at high concentrations this inhibits FSH

Answer 46

Estrogen
