Answer 6

left

Question 7

where are the testicles suspended from?

Answer 7

suspended from the abdomen

Question 8

what are the testicles suspended from the abdomen by?

Answer 8

by the spermatic cord

Question 9

what are the spermatic cords?

Answer 9

collection of vessels, nerves and ducts that supply the testes

Question 10

originally, where are the testis located?

Answer 10

posterior abdominal wall

Question 11

what happens to the testis during embryonic development?

Answer 11

they descend down the abdomen, and through the inguinal canal to reach the scrotum

Question 12

what do the testis carry as they descend?

Answer 12

They carry their neurovascular and lymphatic supply with them

Question 13

what shape are the testis?

Answer 13

ellipsoid shape

Question 14

what do the testis consist of?

Answer 14

a series of lobules, each containing seminiferous tubules supported by interstitial tissue

Question 15

what are produced in the seminiferous tubules?

Answer 15

Spermatozoa

Question 16

where do the developing sperm travel? collecting in?

Answer 16

through the tubules, collecting in the rete testes

Question 17

what transport the sperm to rete testes?

Answer 17

Ducts known as efferent tubules

Question 18

why do sperm need to be transported to the rete testes?

Answer 18

to be taken to the epididymis for storage

Question 19

how many coverings do the testes have and what are they?

Answer 19

The testes have two coverings
tunica vaginalis (outer)
tunica albuginea (inner)

Question 20

where is the tunica vaginalis situated?

Answer 20

externally

Question 21

what do the tunica vaginalis cover?

Answer 21

covering the anterior surface and sides of each testicle

Question 22

what is the tunica vaginalis derived from?

Answer 22

abdominal peritoneum during development

Question 23

what is the tunica albuginea?

Answer 23

a fibrous capsule that encloses the testes

Question 24

where does the tunica albuginea penetrate into?

Answer 24

the parenchyma of each testicle, dividing it into lobules

Question 25

what does the epididymis consist of?

Answer 25

a single heavily coiled duct. It can be divided into three parts; head, body and tail

Question 26

what is the head of the epididymis?

Answer 26

The most proximal part of the epididymis

Question 27

what is the head of the epididymis formed by?

Answer 27

the efferent tubules of the testes

Question 28

what is the function of the head of the epididymis? (function of efferent tubules of testes - head)

Answer 28

transport sperm from the testes to the epididymis

Question 29

what forms the body of the epididymis?

Answer 29

by the heavily coiled duct of the epididymis

Question 30

where is the tail of the epididymis?

Answer 30

The most distal part of the epididymis

Question 31

what does the tail of the epididymis mark?

Answer 31

the origin of the vas deferens

Question 32

what is the function of the vas deferens?

Answer 32

transports sperm to the urethra for ejaculation
