Testes (5)

A
  • Primary male sex organ
  • Enclosed in scrotum
  • Divided into lobules containing seminiferous tubules
  • Seminiferous tubules lined with germinal epithelium cells
  • Germinal epithelium cells divide into sperm during spermatogenesis

Q

Functions of the prostate gland (2)

A

It secretes prostate fluid that

Primary oocyte (2n)
1st meiotic division
Polar body and secondary oocyte
2nd meiotic division
Three polar bodies and a fertilized ovum (if sperm)
17
Q

Menstrual cycle

A

Consists of the ovarian and uterine cycles and lasts 28 days

18
Q

Ovarian cycle (4)

A
  • Pituitary releases FSH
  • Primary follicle into mature Graafian follicle
  • Rupturing of the follicle and the release of the implanted ovum in ovulation, stimulated by LH
  • Formation of the corpus luteum, which secretes progesterone
19
Q

Uterine cycle (5)

A
  • A new endometrium builds up
  • Ovulation takes place
  • Oestrogen and progesterone thicken endometrium
  • The endometrium is very thick. The unfertilised Ovum degenerates
  • The endometrium is destroyed and discarded (menstruation)
20
Q

Fertilisarion (6)

A
  • copulation
  • Sperm enter cervix, pass through uterus into fallopian tube
  • Many sperm surround ovum, secret lytic enzymes to dissolve outside layer
  • the head of one sperm penetrates membrane
  • membrane become fertilised membrane, impenetrable
  • haploid nucleus of the sperm fuses with haploid nucleaus of mature ovum, forming zygote
21
Q

Birth control (6)

A
  • The voluntary regulation of the number of births by preventing pregnancy
  • Main methods
    > Natural methods
    > Barrier methods
    > Chemical substances
    > Surgical methods
22
Q

Natural methods of birth control (2)

A
  • Withdrawal

- Rhythm

23
Q

Barrier methods of birth control (5)

A
  • Male condom
  • Female condom
  • Cervical cap
  • Diaphragm
  • Intra-uterine device IUD
24
Q

Chemical substances of birth control (3)

A
  • Spermicides
  • Contraceptive Pill
  • Contraceptive injections
25
Q

Surgical methods of birth control (2)

A
  • Vasectomy

- Tubal ligation
