Q

Male reproductive system

A

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:

Q

Seminal vesicle

A

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

Divided pouch

Temperature regulation to facilitate sperm production 4°F cooler

17
Q

FSH in female

A

Stimulate one oocyte To Mature each month

18
Q

LH in female

A

LH triggers ovulation or release of mature OOCYTE from ovarian follicle

19
Q

Ovum

A

Mature oocyte

20
Q

Fimbriae

A

Hair like Projections at end of fallopian tubes

Move newly ovulated ovum into fallopian tube

21
Q

Fallopian tube

A

Site of fertilization

Can be sterilized by “ tubal ligation “

22
Q

3 layers of uterine wall

EMP

A
  1. Endometrium: shed each month
  2. Myometrium: middle muscle layer
  3. Perimetrium: outer layer
23
Q

3 regions of uterus

A

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

24
Q

Vagina

A

Contains Rugae transverse folds.

Bartholin glands secrete mucous for lubricant.

25
Q

Milk production hormones

A

Pituitary hormones
Prolactin - milk production
Oxytocin - milk expression

Estrogen stimulate duct development

Progesterone stimulates secretory cells

26
Q

Zygote

A

Fertilized ovum

27
Q

Sertoli cell

A

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

28
Q

Menstrual cycle phases

A

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

29
Q

Number of chromosomes in sex cell and regular cell

A

Sex cell 23

Regular 46

30
Q

Male reproductive organs
Primary
Secondary
Accessory

A

Primary- gonads testes

Secondary- spermatic duct
Epididymus, vas deferens, ejaculatory ducts, urethra

Accessory - Seminole vesicles, prostate, bulbourethral glands

31
Q

hCG

A

Human chorionic gonadotropin

Secreted by placenta until placenta takes over for the corpus luteum

Maintains corpus luteum

One cause of morning sickness

32
Q

Blastocyte

Day 16

3 layers

A

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

33
Q

Relaxin

A

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

34
Q

Inheritance

A

Expression of traits and conditions passed from one generation to another

35
Q

DNA

A

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

36
Q

Gene

A

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

37
Q

Genetics

A

Study of inheritance

38
Q

Mutation

A

Mistake in our gene coding

39
Q

Chromosomal disease

A

Down syndrome - three #21 chromosomes

Turners syndrome- only one X chromosome

40
Q

Gene diseases

A

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.
