Q

S Phase

A

Chromatids replicate so now each cell has 46 chromsomes. 23 from mom, 23 from dad with each chromosome having two chromotids connected by a cetromere

Q

Prophase I

A

nucleus disolves, Homologous Chromosomes line up (synapsis). So #1 from mom next to #`1 from dad etc. Then crossover takes place. Homologous Genetic material from mom and dad swap in random places on chromotids.

Q

Meiosis II

A

splits the remaining sister chromatids apart. Creating two more cells. So know 4 cells each with 23 single chromatid chromosomes

Q

andr

A

man

17
Q

Ejacul

A

to short forth

18
Q

Mamm

A

breast

19
Q

Puber

A

adult

20
Q

Oo

A

egg

21
Q

Zygote

A

diploid cell resulting from the joining of two sex cells

22
Q

Sustentacular cells

A

inside tubulars of testies help provide nutrients for developing sperm

23
Q

Interstitial cells

A

right outside of tubulars and produce testotorone

24
Q

epidydmus

A

long coiled tube that sits on top of the testies that help store and transport sperm. Rythmic peristalic contracts help them mature, but they don’t move independently till after ejaculation

25
Q

vas deferens

A

muscular hollow tube that connects testicles. Eventaully joins with seminal ducts and becomes ejaculatory duct

26
Q

seminal vesicle

A

releases glucose which goes to mitcondria of sperm allowing them to swim, also secrets prosaladin for uterine contractions and alkaline fluid

27
Q

prostate gland

A

produces milky white alkaline substance, helps sperm move faster

28
Q

Bulbourthral gland

A

produces precum

29
Q

gubernaculum

A

pulls testicles into scrotum

30
Q

spermatic cord

A

attaches testicles to body

31
Q

tunica albuginea

A

tough fiborous capsule enclosing each testicle

32
Q

acrosome

A

sperm hat, releases enzyme to penetrate egg cell

33
Q

corpora cavernosa

A

erectile tissue

34
Q

corpus spongiosum

A

erectile tissue

35
Q

male sex hormones

A

androgen and testosterone, androgen most important
