Answer 14

Ovaries

Question 15

What are the three accessory reproductive organs

Answer 15

-Uterine tubes
-Uterus
-Vagina

Question 16

Body of uterus wall has 3 layers

Answer 16

• perimetrium
• myometrium
  -endometrium

Question 17

Anteverted and anteflexed

Question 20

Describe the position of the ovaries

Answer 20

• Almond sized and amped , located laterally in the pelvic cavity
• develop on the posterior abdominal wall and move onto the lateral wall of the pelvis

Question 22

Whats do ovaries do

Answer 22

Secret oestrogen and progesterone in response to pituitary hormones

Question 23

What are the stages of fertilization and menstruation

Answer 23

• ova develops in ovaries
  -each menstrual cycle , 1 ovum is released from the surface of ovary into peritoneal cavity
  -ovum is gathered by fimbriae into infundibulum of uterine tube
  Moved along uterine tube by cillia
  -during menstruation , an unfertilized ovum is expelled by contractions of the myometrium

Question 24

Where does fertilization normally occur

Answer 24

In ampulla

Question 25

What’s ectopic pregnancy what’s potential emergency

Answer 25

- fertilized ovum implants out with the uterine cavity - danger of hemorrhage (loss of blood from damaged blood vessels )

Question 27

Female sterilization

Answer 27

TUBUAL LIGATION - both uterine tubes -clipped , cut and (cauterized - electric current used to burn and seal the fallopian tubes shut , creating scar tissues that block the passage of an egg prevent fertilization ) -blocks the lumen

Question 28

Stages of testes development

Answer 28

-dusting development the testis originate on the posterior wall of the abdominal cavity -by birth they have descended into the scrotum - through the anterior abdominal wall -inguinal canal -th tube that sperm pass through follows the testis into the scrotum - the vas (vas deferens) -the vas connects the testis to (almost ) the urethra

Question 29

Sperm produced in …. Passed to …. Then to ….

Answer 29

Seminiferous tubules -temp -1degrees C below core body temp Rete testis Then to head of epididymis -epididymis becomes vas deferens

Answer 30

-vas deferens -Testicular artery -pampiniform plexus vein (more complex )

Question 31

What’s titration of testis and what does it cause

Answer 31

-twisting of spermatic cord - distrusts blood supply -Severe pain -Danger of testicular necrosis ( death of testicular tissue )

Question 32

Sperm develops where

Answer 34

Testes

Question 35

Sperm pass from testis via what

Answer 35

Vas deferens

Question 36

Each vas deferens lies within the

Answer 36

Spermatic cord

Question 38

Each spermatic cord passes through

Answer 38

-Anterior abdominal wall -within the inguinal canal to reach the pelvic cavity

Question 39

How does vas deferens produce seminal fluid

Answer 39

- within the pelvis each vas deferens connects with the duct from seminal gland (produces seminal fluid ) to form an ejaculatory duct containing semen

Question 40

Whats semen

Answer 40

Sperm and seminal fluid Produced in seminal gland

Question 41

How does the ejaculatory ducts drain. Into the urethra

Answer 41

- right and left ejaculatory ducts join together within the prostate gland (immediately inferior to the bladder ) and drain into the urethra -the urethra opens at the external urethral meatus of the penis
