New cards
10

prostaglandins

have local effects/initiate smooth muscle contraction

New cards
11

fructose

helps the sperm cell have energy

New cards
21

whats in the head of the sperm

acrosome, nucleus

New cards
22

what does the acrosome do

a hard cap on the sperms head to break through the egg

New cards
23

midpiece includes what

mitochondria

New cards
24

another word for tail

flagellum

New cards
25

the order for meiosis for sperm

spermatogonia (stem cells) - primary spermatocytes - secondary spermatocytes - spermatid - mature sperm

New cards
26

where is spermatogonia found

edge of seminifourous tubules

New cards
27

another statement for development of sperm

process of meiosis

New cards
28

in meiosis the chromosome is

being halved 46 - 23

New cards
29

how many PRIMARY spermatocyte is there

one

New cards
30

the primary spermatocytes divides into what

four

New cards
31

primary spermatocytes have how many chromosomes

46

New cards
32

2 secondary spermatocytes have how many chromosomes

23

New cards
33

4 spermatid have how many chromosomes

23

New cards
34

4 mature sperm have how many chromosomes

23

New cards
35

gamete

sex cell (egg + sperm)

New cards
36

meiosis is specilized to

sex cells

New cards
37

half chromosome #'s is also called

a HAPloid cell

New cards
38

ovaries

follicle makes 2 hormones (estrogen and progesterone)

New cards
39

fallopian tube

transports the egg from ovary to uterus fimbria sweep in the egg after its been ovulated

uterus

where the fertilized ovum will implant and develop

New cards
43

2 parts of the uterus

myometrium and endometrium

New cards
44

myometrium

outer muscular layer lots of progesterone and oxytocin receptors

New cards
45

endometrium

inner nutrient-rich lining (blood) nourishes the embryo or is shed every 28 days (menstration) estrogen also causes it to grow back every month

New cards
46

cervix

a strong muscular band at lower end of uterus prevents fetus from entering birth canal

New cards
47

what is the cervix plugged with

mucus

New cards
48

vagina

muscular canal that connect uterus to the external environment/ acidic

New cards
49

primary sex charateristics (female)

repro structures that develop in utero and are present at birth (lack of y chromosome) XX

New cards
50

secondary sex characteristics (female)

puberty indluenced by hormones (estrogen) / thickening of endometrium maturation of vagina
