1

Male gametes?
Female gametes?

Spermatozoa
Oocyte or ovum

2

Are gametes diploid or haploid?

Haploid

3

Male gonad?
Female gonad?

Testicle
Ovary

4

What is formed when a spermatozoa fertilises an oocyte?

Zygote (diploid)

5

What does the pelvic floor (pelvic diaphragm) separate?

Separates the pelvic cavity and perineum (internal wall of skeletal muscle)

6

What is inferior to the pelvic floor?

The perineum (includes both skin and underlying muscle

7

What forms the pelvic roof?

Parietal peritoneum

8

What is the name of the pouch between the bladder and uterus?

Vesico-uterine pouch

9

What is the name of the pouch between the rectum and uterus?

Rectouterine pouch (of Douglas) - most inferior part of the peritoneal cavity

10

What are the 3 holes that women have in their perineum? - from anterior to posterior

External urethral orifice
Vaginal orifice
Anus

11

What is the female reproductive organs?

Ovaries

12

What are the accessory reproductive organs? (3)

Uterine tubes
Uterus
Vagina

13

What are the 3 layers of the body of the uterus wall?

Perimetrium
Myometrium
Endometrium

14

What is the neck of the uterus called?

The cervix

15

Parts of the uterine tubes (from the ovaries to the uterus)? (4)

Fimbriae of the peritoneal cavity
Infundibulum
Ampulla
Isthmus

16

What happens after the ovum is released from the surface of an ovary?

The ovum is released into the peritoneal cavity and is then gathered by the fimbriae into the infundibulum of the uterine tube

17

How is the ovum moved along the uterine tube?

By the cilia

18

What happens during menstruation?

An unfertilised ovum is expelled by contractions of the myometrium

19

What happens during an ectopic pregnancy?Where can this be?

The fertilised ovum implants outwith the uterine cavity tubal pregnancy (97%) or abdominal pregnancy

20

Why is an ectopic pregnancy a potential emergency?

Danger of haemorrhage

21

What is involved in female sterilisation?

Tubal ligation
Both uterine tubes are either clipped, cut or cauterised

22

What is the position of the anatomical position of the penis?

Erect (anterior surface is at front when erect)

23

What is the hole on the penis?

The external urethral orifice

24

What is the scientific name for the hood of the penis?

Prepuce

25

Where does the testis originate during development?

On the posterior wall of the abdominal cavity

26

What do the testis pass through when the descend into the scrotum?

Through the anterior abdominal wall (inguinal canal)

27

What is the tube that sperm pass through which connects the testis to (almost) the urethra?

Vas deferens (follow the testis into the scrotum)

28

What does the inguinal canal convey in women?

The round ligament of the uterus

29

Where are sperm produced?

In the seminiferous tubules

30

What is the temp. of the seminiferous tubules?What helps to control this?

About 1 degree below core body temperature
Dartos muscle helps to control temp.
