Male structure

Question 1

What is a Testes?

Answer 1

A male gonads ( sex organ )

Question 2

What do Testes produce?

Answer 2

They produce sperm and sex hormones

Question 3

What is needed in order for healthy sperm to produce?

Answer 3

Sperm does not produce well in body temperature therefore it is in the scrotum where it is located more on the outer side of the body

Cooler temperature in producing sperm will result in a more healthy sperm where as sperm created in body temperature

Question 4

Testes are found..

Answer 4

in a sac called scrotum

Question 5

Testes walls are made up of fibrous connective tissues where it divides the testes into lobules / chambers. Inside the chambers are long tubules which are 70 cm long (they are arranged and look like a small intestine), they are called..

Answer 5

spermatogenesis

Question 7

What is spermatogenesis?

Answer 7

Sperm development

Question 8

Sperm cells came from undifferentiated cells called..

Answer 8

Spermatogonia ( Spematogonium ( Diploid ) )

Question 9

Spermatogonia cells lie on..

Answer 9

the outside wall of the seminiferous tubules and they divide and separate producing new spermatogonia

Question 10

Newly created spermatogonia cells move inwards away from the outer tubules to become..

Answer 10

primary Spermatocytes which under goes meiosis

Question 11

Primary spermatocytes are spermatogonia cells that are bigger and away from the outer seminiferous tubules, these spermatocytes under goes..

Answer 11

meiosis, a type of cell division

Question 12

Primary Spermatocytes with 46 chromosomes divide producing 2..

Answer 12

secondary spermatocytes with 23 chromosomes

Question 13

In a seminiferous tubules, spermatogonia cells divided producing a different type of cell while moving inward, list them starting from the outer going to the inner tubules (there is 5)..

Answer 13

Spermatogonia, primary spermatocytes, secondary spermatocytes, early spermatids and immature sperm

Question 14

Secondary spermatocytes then divide into 4 spermatids also with 23 chromosomes but each one has a..

Answer 14

chromatid ( DNA )

Question 15

Spermatids then differentiates into..

Answer 15

spermatozoa

Question 16

Also in the seminiferous tubules, there are Sertoli cells which..

Answer 16

support, nourish and regulate spermatogenic cells

Question 17

What is the purpose of the Epididymus?

Answer 17

stores sperm as they mature, they acquire the ability to swim

Question 18

What is the purpose of the seminal vesicle?

Answer 18

Contributes to seminal fluid

Question 19

What is the bulbourethral gland / Cowper’s gland?

Answer 19

A pea size organ that lie on either side of the urethra, also contributes to seminal fluid

Question 20

Where is the prostate gland located?

Answer 20

It surrounds the upper part of the urethra just below the bladder. As men gets older, it becomes bigger making it hard to urinate

Question 21

What is the purpose of the prostate gland?

Answer 21

Helps produce seminal fluid

Question 22

What is the purpose of the urethra?

Answer 22

to conduct sperm and urine out the body

Question 23

What is the purpose of the Ductus Deferens?

Answer 23

Stores and moves sperm from the teste to the urethra. The difference between the Ductus Deferens and the Epididymus is that while both holds sperm, the Ductus Deferens carries it from the teste to the urethra

Question 24

What is the purpose of the penis?

Answer 24

Serves as an organ of copulation ( sexual intercourse )
