Variation

New gene combinations

1

Testes secrete hormones...

That help shape the body as well as mental attitudes

2

Testes

-Cryptochildish develpos if the testes do not descend

3

Epididymis

Surface of the testes where sperm mature and are stored prior to ejaculation.

4

Scrotum

-loose pouch
-paired testes
-2 degrees below body
-cremasteric and dartos muscles: contract in responses to temp

5

Spermatic cord

-muscles
-arteries and veins
-nerves
-vas deferens

6

Vas Deferens

Tubes that transport the sperm during ejaculation

7

Vasectomy

The cutting of the vas Deferens is a male birth control procedure.

8

Spermatozoa

-produced at a rate of millions per day
- sperm + additives = semen
-live 2 days in the female tract

9

Seminiferous tubules

Sertoli cell : FSH ~make sperm
Interstitial cells : LH

10

Urethra

Conducts the sperm out into the vagina

11

Seminal vesicle

Help make up the sperm

Also a buffer to neutralize what is in the urethra and vagina

12

Prostate gland

Acts like a billow during

13

Cowpeas gland

Secretes lubricant
Neutralize the acidic conditions inside the vagina

14

3 glands that help with ejaculation

Seminal vesicle
Prostate gland
Coppers gland

15

Penis

Glans
Prepuce
Corpora cavernousa

16

Why additives need to be added to the sperm

1) provide nutrients
2) transport
3) neutralize the acidity

17

Gonads / testes- that produce sperm

18

Secondary sex ograns

Epididymis, vas Deferens, seminal vesicles, prostate gland, Cowper's gland and penis

Produce sperm cells

27

Spermatogenesis

Making sperm

28

Cooties

Pubic lice

29

Ovaries

-paired almond
-contain 300000 follicles at birth
-decline to about 12000 at puberty
-only about 400 of these will be ovulated

30

-Finger like extensions off the top of the Fallopian tube
-sweep the egg into the opening of the Fallopian tube

31

108 cells

32

-muscular organ about the size of a fist
-fundus
-body
-cervix
-endometrium

33

Vagina

-birth canal
-10cm

34

Bartholins gland

Located inside the vagina
- secretes a fluid that lubricates the vagina to assist in copulation

35

Vulva

-mons pubis
-labia majora
-labia minora
-clitoris

36

Mons pubis

Protective pad during colitis and contains the pubic hair

37

Labia majora

-Pubic hair is present
-sweat glands
-other lubricating glands
Folds of skim protect the opening of the vagina

38

Labia minora

- no pubic hair or sweat glands
-folds also protect the opening of the vagina

39

Clitoris

Erectile tissue as well as a protective structure

40

Cervix

-forms a plug during pregnancy
-2nd most common location for cancer in females

41

Mammary glands

-fatty deposits & glands that secrete milk through a series of tubes to the nipple

42

Production of milk requires

-estrogens
-progesterones
-prolactin

Oxytocin is necessary for milk let down

43

Felp

Ovulation, fertilization, implantation, HCG, endometrium, estrogen, progesterone, FSH, LH, Fallopian tube, distal 1/3, fimbrae, ovum, follicle, corpus luteum, sperm, vagina, cervix, zygote, blastocyst, placenta, embryo, acrosome, uterus

44

The primary sex organs of the female

Ovaries-----which produce the ova (egg) and store till ovulation

45

Secondary sex organs are

Uterine tubes
Vagina
Uterus
Mammary glands

46
