What are the haploid cells?
male - spermatozoa
female - oocyte/ ovum
What are the gonads?
where the haploid cells are produced
male = testes
female = ovaries
What is the diploid cell produced in fertilization called?
What are the primary female reproductive organs?
What uterus layer comes away in menstration?
What are the 3 layers of the uterus wall?
What are the accessory organs of the female reproductive system?
The uterine tubes
Where does fertilisation occur?
In the ampulla
Where does implantation occur?
in the body of the uterus
What are the steps of the ovum’s life cycle in a menstrual cycle?
- ova develops in ovaries
- each menstrual cycle, 1 ovum is released from surface of ovary into peritoneal cavity
- ovum is gathered by fimbriae into infundibulum of uterine tube
- moved along uterine tube by cilia
- during menstruation, an unfertilised ovum is expelled by contractions of the myometrium
What is an ectopic pregnancy?
where the fertilisation implants outside of the uterine cavity
this is a potential emergency due to the danger of haemorrhage
What is the process of female steritilisation?
where both uterine tubes are clipped, cut or cauterised which blocks the lumen
What is the process of testes development?
they originate on the abdominal cavity’s posterior wall
they’ve descended to the scrotum by birth through the inguinal canal - the anterior abdominal wall
What is the vas (vas deferens)?
the tube that sperm pass through - follows the testis into the scrotum and connects the testis almost to the urethra
Where are sperm produced?
in the seminiferous tubules
What is the path sperm take into the vas deferens?
they pass to rete testis then into the head of epididymis which then becomes the vas deferens
What is the temperature needed for sperm development?
roughly 1 degree below core body temperature dartos muscle helps to control this
What is contained within the spermatic cord?
pampiniform plexus of veins
What is torsion of testes?
twisting of spermatic cord
disrupts blood supply
danger of testicular necrosis
What are the changes in blood supply to the penis during erection?
3 cylinders of erectile tissue become filled with blood at arterial pressure
What are the primary male reproductive organs?
What are the male accessory reproductive organs?
What is the procedure of male sterilisation?
Vasectomy - vas deferens is transected and its lumen is sutured closed bilaterally
How do the spermatic cords pass into the pelvic cavity?
through the anterior abdominal wall within the inguinal canal
How do the vas deferens become the ejaculatory duct containing semen?
They connect with the seminal duct gland (which produces seminal fluid) to form the ejactulatory duct
Where does the urethra open in a man?
at the external urethral meatus of the penis
What is path of the sperm from development in the testes to ejection through the urethra?
sperm passes from the testis to vas deferens within the spermatic cord
the vas deferens become the ejacuatory duct the right and left ejaculatory ducts join in the prostate gland and drain into the urethra
Where is the prostate located?
immediately inferior to the bladder
