the testes and spermatic cord

Question 1

describe the position of the testes during development

Answer 1

originate on posterior wall of abdominal cavity and descend down through the abdominal wall(inguinal canal) into the scrotum. the vas deferens follows the testes

Question 2

state what part of the testes spermatogenesis takes place and the conditions required

Answer 2

sperm is produced in the seminiferous tubules of the testes at:- 1C below body temp.

Question 3

describe the route of sperm from the seminiferous tubules to the vas deferens

Answer 3

produced and stored in tubules, then pass to rete testis, then into head of epididymis, then its tail and then into the vas deferens

Question 4

what is contained within the spermatic cord

Answer 4

vas deferens, testicular artery and the pampiniform plexus(network) of veins

Question 5

describe the condition torsion of the testes and its symptoms

Answer 5

twisting of spermatic cord, disrupts the blood supply to testes, causes severe pain and danger of testicular necrosis(death)

Question 6

describe the anatomy of the penis

Answer 6

bulb of penis(proximal part)
root of 
body of
glans(head)
external urethral orifice

Question 7

state the organs and accessory organs in the male reproductive system

Answer 7

organ = testes

accessory organs = seminal glands, prostate gland, vas deferens and penis

Question 8

explain the path of sperm from testes to the pelvis

Answer 8

sperm develops in testes
passes from testis/epididymis to vas deferens(within spermatic cord)
each spermatic cord passes through anterior wall of abdomen(through inguinal canal) into pelvic cavity

Question 9

explain the path of sperm from the spermatic cord in the pelvic cavity to ejaculation

Answer 9

within pelvis each vas deferens connects to a duct from a seminal gland to form an ejaculatory gland containing semen
R and L ejaculatory gland join in prostate gland and drain into urethra
urethra opens at external oriphice

Question 10

what is the function of the seminal gland and what does semen contain

Answer 10

seminal gland produces seminal fluid and semen is the combination of seminal fluid and sperm

Question 11

where is the prostate gland located

Answer 11

immediately inferior to the bladder, anterior to the rectum

Question 12

describe the sterilisation of the male reproductive system

Answer 12

vasectomy, vas deferens is transected(cut transversely), and its lumen sutured closed at both ends on both the L and R vas deferens
