Q

what is the pelvic roof

A

this is formed by a thin lining of the abdominal cavity (firmly attached to walls, drapes over organs) called the parietal peritoneum

Q

talk through the fertilisation/ menstrual process

A

ovum develops in ovaries, every menstrual cycle 1 ovum is released from the ovaries into the peritoneal cavity.
it is then gathered by fimbriae and cilia push the ovum along the uterine tube. the ovum (and parts of endometrium) are expelled by contractions of the myometrium.

16
Q

where does fertilisation occur and where does implantation occur

A

ampulla and uterus

17
Q

what is ectopic pregnancy and what are the 2 types of ectopic pregnancy

A

when the zygote implants outside the uterine cavity; tubal or abdominal.

18
Q

what is the main danger of ectopic pregnancy

A

haemorrhage

19
Q

why are ectopic pregnancies dangerous

A

not enough tissue to accommodate growth so tissue bursts

20
Q

what can STIs cause

A

spread via the uterine cavity to reach the peritoneal cavity causing peritonitis

21
Q

how can STIs cause infertility

A

by causing damage to uterine tubes creating scar tissue which then blocks them.

22
Q

what are the types of sterilisation for males and females and what do they consist of

A

females; tubal ligation: both uterine tubes are cut and lumens blocked
males: vasectomy: vas deferent cut sutured closed blocking the lumen

23
Q

name the elements of the surface peritoneum of males

A

scrotum, anus, urethra, prepuce, body of penis, root of penis, external urethral orifice

24
Q

describe the development of the testis

A

during development the testis are found in the posterior wall of the abdominal cavity, they then descend into the scrotum through the inguinal canal. the vas follows. the testis into the scrotum and hence connects testis and urethra.

25
Q

where’s sperm produced

A

seminiferous tubules

26
Q

what means are used in order to keep the sperm at a constant cool temperature

A

held outside of body in testis, Dartos muscle (involuntary) can cause changes (e.g. shrinkage) to warm up testis

27
Q

what is the pathway of sperm

A

Sem.Tub- rete testis- epidymus- vas deferens- passes through inguinal canal to reach pelvic cavity, vas deferent joins to seminal vesicles which forms the ejaculatory duct. the prostate gland brings the left and right ejaculatory ducts together and through the urethra into the bulb of the penis

28
Q

what does the spermatic cord contain

A

vas deferens, testicular artery and pampiniform plexus of veins

29
Q

what is torsion of testes and the dangers associated with it

A

twisted spermatic cord, low blood supply which causes pain and danger of testicular necrosis

30
Q

how does an erection occur

A

3 cylinders of erectile tissue are engorged with blood at arterial pressure

31
Q

what is the 1 true reproductive organ for males

A

testis

32
Q

what are male accessory reproductive organs

A

vas deferens, seminal vesicles, prostate gland, penis
