Answer 1

hormonogenesis, gametogenesis, gamete transport, genetic contribution to offspring (pregnancy)

Question 2

What is the function of the ovary? (2)

Answer 2

produce eggs, synthesize sex steroids (estrogen + progesterone)

Question 3

What is the medulla?

Answer 3

inside tissue of the ovary that contains blood vessels and nerves

as follicules grow, they move around the edge of the cortex, building outer casing while oocyte stays the same

Question 5

What are the functions of the oviduct? (3)

Answer 5

structure for oocyte capture and transport, transporting sperm to egg, fertilization cite

Question 6

What is the infundibulum?

Answer 6

catches eggs released, mouth of oviduct

Question 7

What is the ampulla?

Answer 7

where egg and sperm meet (fertilization) top of oviduct

Question 8

What is the isthmus?

Answer 8

sperm reservoir to meet egg during ovulation (right by uterine horn)

Question 9

What do the oviduct secretions do? (2)

Answer 9

provide optimum oocyte and zygote (while it travels) environment, aid sperm mobility

Question 10

What are the functions of the uterus? (4)

Answer 10

structure for sperm transport, regulation of luteolyosis (regression of corpus luteum (CL)), cyclitity, environment for pregnancy, secretes hormones

Question 11

What does the perimetrium of the uterus do?

Answer 11

outermost layer of the uterus, protects the organ and provides support

Question 12

What does the myometrium of the uterus do?

Answer 12

Answer 13

thickest layer, maintenance of pregnancy, menstruation

Question 14

What does the cervix do?

Answer 14

regulates access into uterus as a barrier

Question 15

What do the secretions of the cervix do? (3)

Answer 15

provide lubrication to promote/inhibit sperm, flush out microorganisms, seal of uterus during pregnancy ( cilia)

Question 16

What does the vagina do?

Answer 16

copulatory organ (device used to transfer/receive sperm)

Question 17

What do the vaginal secretions do?

Answer 17

aid in intercourse, inhibit microorganism growth, maintain acidic pH

Question 18

What do Sertoli cells do? Where are they located?

Answer 18

In the seminiferous tubules, help immature sperm grow and become mature

Question 19

What do the testis do? (2)

Answer 19

produce male gametes, synthesize testosterone

Question 20

Which cells produce testosterone in the testis?

Answer 20

Leydig cells

Question 21

What does the epididymus do? (3)

Answer 21

sperm transport, regulate maturation and fertilization capacity of sperm, contributes to seminal plasma

Question 22

What is the rete testis?

Answer 22

central duct where all of the mature sperm funnel into

Question 23

What is the significance of the theca and granulosa cells?

Answer 23

the granulosa cells are around the growing oocyte but can’t make CYP 19 so the theca cells make it and its transported to granulosa cells

Question 24

What takes pregnenolone to hydroxy, hydroxy to DHEA?

Answer 24

CYP17

Question 25

What converts testosterone to estradiol?

Answer 25

CYP 19

Question 26
