Reproductive System Chapter 25

Question 1

Primary sexual organs

Answer 1

Gonads

Question 2

Gamete

Answer 2

Male and female sex cells

Question 3

Andrology

Answer 3

Male reproductive and urine system study

Question 4

Basic reproductive anatomy

Five things

Answer 4

Gonads gametes

Ducts,

Male accessory organs and glands
Penis, prostate, bulbourethral glands, seminal vesicles

Female accessory organs and glands
Uterus, Bartholin glands, breast

Question 5

2 Functions of reproductive system

Answer 5

Produce offspring

Hormone production and secretion

Question 6

Male reproductive system

Answer 6

STEVE-U

Seminiferous tubule‘s: Sertoli cell sperm born here inside testes

Epididymis: final maturation

Vas deferens: leave epididymis to join seminal fluid at Jack with Tori duct

Ejaculatory: prostate 25%, bulbourethral 5%, Seminole bicycles 60%, sperm 10%

Urethra:

Question 7

Cells of Leydig

Answer 7

In the testes produce testosterone

Question 8

FSH

Answer 8

Follicle stimulating hormone from the anterior pituitary stimulates sperm production

Question 9

Cells of leading

Answer 9

Luteinizing hormone from and Anterior pituitary stimulates interstitial cells of ladybug to produce testosterone

Question 10

Seminal vesicle

Answer 10

60% of semen volume
Alkaline
Sugar prostaglandins and fibrinogen
Prostaglandins “contraction of smooth muscle” in female reproductive system this helps invoke labor

Nourish sperm on journey

Fibrinogen is a lumping agent

Question 11

Prostate function

Answer 11

Produce relaxing enhance sperm motility and function

alkaline fluid

Question 12

Scrotum

Answer 12

Divided pouch

Temperature regulation to facilitate sperm production 4°F cooler

The cremaster muscle draws testes closer to or away from body

Question 13

Female primary reproductive organ

Answer 13

Ovaries

Estrogens with FSH & LH produced by anterior Pituitary facilitate sequence of events during menses

Question 14

Estrogen

Answer 14

Development of female sex organs and secondary sex characteristics during puberty

Question 15

Progesterone

Answer 15

Maintain the uterine lining for implantation and pregnancy

Question 16

Oocytes

Answer 16

Contained in ovarian follicles (graafian)

Female born with all oocytes they will ever have

Question 17

FSH in female

Answer 17

Stimulate one oocyte To Mature each month

Question 18

LH in female

Answer 18

LH triggers ovulation or release of mature OOCYTE from ovarian follicle

Question 19

Ovum

Answer 19

Mature oocyte

Question 20

Fimbriae

Answer 20

Hair like Projections at end of fallopian tubes

Move newly ovulated ovum into fallopian tube

Question 21

Fallopian tube

Answer 21

Site of fertilization

Can be sterilized by “ tubal ligation “

Question 22

3 layers of uterine wall

EMP

Answer 22

1. Endometrium: shed each month
2. Myometrium: middle muscle layer
3. Perimetrium: outer layer

Question 23

3 regions of uterus

Answer 23

Body: hollow cavity
Fundus: uppermost region
Cervix: opening into vagina

Question 24

Vagina

Answer 24

Contains Rugae transverse folds.

Bartholin glands secrete mucous for lubricant.

Question 25

Milk production hormones

Answer 25

Pituitary hormones Prolactin - milk production Oxytocin - milk expression Estrogen stimulate duct development Progesterone stimulates secretory cells

Question 26

Zygote

Answer 26

Fertilized ovum

Question 27

Sertoli cell

Answer 27

Cells Surround the seminiferous tubule that support protect and nourish the developing sperm

Question 28

Menstrual cycle phases

Answer 28

Follicular phase: Day 1-13; day 1 of discharge of endometrial lining 5days maturation of ovarian follicles. Ovulation: Day 14; surge of LH release of mature oocyte now Ovum. Collapsed follicle now is Corpus Luteum. Literal phase: Day 15-28. Corpus luteum secrete estrogens and progesterone which maintain uterine lining. Relaxin relaxes uterus and Inhibin stops FSH and LH If no fertilization corpus luteum turns into corpus albicans dropping progesterone and estrogen levels

Question 29

Number of chromosomes in sex cell and regular cell

Answer 29

Sex cell 23 Regular 46

Question 30

Male reproductive organs Primary Secondary Accessory

Answer 30

Primary- gonads testes Secondary- spermatic duct Epididymus, vas deferens, ejaculatory ducts, urethra Accessory - Seminole vesicles, prostate, bulbourethral glands

Question 31

hCG

Answer 31

Human chorionic gonadotropin Secreted by placenta until placenta takes over for the corpus luteum Maintains corpus luteum One cause of morning sickness

Question 32

Blastocyte Day 16 3 layers

Answer 32

3 primary germ layers Ectoderm- outermost layer. Nervous, inner ear and eye, mucosa of mouth and anus, epidermis of skin Mesoderm- muscles, connective tissue. Blood lymph and hypodermis. Urogenital tract Endoderm- lining of gastrointestinal tract, lining of respiratory passages, most tissues of glands and organs, lining of body passages, covering for most internal organs

Question 33

Relaxin

Answer 33

Hormone that increases flexibility of the pubic symphysis and helps the cervix dilate assisting in Fetal delivery

Question 34

Inheritance

Answer 34

Expression of traits and conditions passed from one generation to another

Question 35

DNA

Answer 35

Deoxyribonucleic acid Chemical found in each cell in the body the codes for the production of enzymes 23 pairs or 46 chromosomes Small coiled spring

Question 36

Gene

Answer 36

Section of DNA on a chromosome that codes for a specific enzyme

Question 37

Genetics

Answer 37

Study of inheritance

Question 38

Mutation

Answer 38

Mistake in our gene coding

Question 39

Chromosomal disease

Answer 39

Down syndrome - three #21 chromosomes Turners syndrome- only one X chromosome

Question 40

Gene diseases

Answer 40

Caused by mistake in the DNA code of a particular gene on a particular chromosome Example Huntington’s, cystic fibrosis, sickle cell disease, muscular dystrophy, spina bifida.
