Reproductive System Chap 22

Question 1

somatic cells

Answer 1

every cell but sex cells. Have 46 chromosomes total

Question 2

sex cells

Answer 2

contain 23 chromosomes. Sperm and oocytes

Question 3

gametes

Answer 3

mature sex cells, sperm of oocytes

Question 4

diploid cell

Answer 4

contains 2 sets of chromosomes, 23 each for a total of 46

Question 5

haploid cell

Answer 5

contains 1 set of 23 chromosomes

Question 6

Autosomes

Answer 6

Chromosomes 1-22

Question 7

Sex Chromsomes

Answer 7

Chromosome 23

Question 8

Mitosis

Answer 8

Replication of somatic cell

Question 9

Meiosis

Answer 9

Replication of sex cell

Question 10

S Phase

Answer 10

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

Question 11

Prophase I

Answer 11

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.

Question 12

Metaphase

Answer 12

centrosomes release spindle fibers attaching to kinetchore and pull chromomes to the middle

Question 13

Anaphase

Answer 13

Homologous chromosomes are now pulled apart from each other by spindle fibers

Question 14

Telephase

Answer 14

splitting takes place as new nucleus’s form. This is also called cytokensis

Question 15

Meiosis II

Answer 15

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

Question 16

andr

Answer 16

man

Question 17

Ejacul

Answer 17

to short forth

Question 18

Mamm

Answer 18

breast

Question 19

Puber

Answer 19

adult

Question 20

Oo

Answer 20

egg

Question 21

Zygote

Answer 21

diploid cell resulting from the joining of two sex cells

Question 22

Sustentacular cells

Answer 22

inside tubulars of testies help provide nutrients for developing sperm

Question 23

Interstitial cells

Answer 23

right outside of tubulars and produce testotorone

Question 24

epidydmus

Answer 24

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

Question 25

vas deferens

Answer 25

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

Question 26

seminal vesicle

Answer 26

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

Question 27

prostate gland

Answer 27

produces milky white alkaline substance, helps sperm move faster

Question 28

Bulbourthral gland

Answer 28

produces precum

Question 29

gubernaculum

Answer 29

pulls testicles into scrotum

Question 30

spermatic cord

Answer 30

attaches testicles to body

Question 31

tunica albuginea

Answer 31

tough fiborous capsule enclosing each testicle

Question 32

acrosome

Answer 32

sperm hat, releases enzyme to penetrate egg cell

Question 33

corpora cavernosa

Answer 33

erectile tissue

Question 34

corpus spongiosum

Answer 34

erectile tissue

Question 35

male sex hormones

Answer 35

androgen and testosterone, androgen most important
