Male Reproductive Sustem

Question 1

where is sperm produced and what happens

Answer 1

sperm is produced in the testes, travels into the epididymis, is carried by the vans deferens up and over the bladder into the ejaculatory duct enters the urethra

Question 2

What is the function of the male reproductive system

Answer 2

isto produce androgens such as testosterone that maintain male reproductive function and to promote spermatogenesis and transport into the female reproductive system for fertilization.

Question 3

where is the scrotum located

Answer 3

this lies below the symphysis pubis in front of the upper parts of the thighs and behind the penis

Question 4

what is the scrotum anatomy internal

Answer 4

the scrotal septum divides the scrotum into two sacs.
Each sac contains:
the testicular end of a spermatic cord one epididymis, and
one testis.

Question 5

what is the scrotum anatomy external

Answer 5

looks like a single pouch of skin separated into two by a median ridge called the raphe

Question 6

what are the Muscles and Movement of the scrotum

Answer 6

the subcutaneous tissue contains
the cremaster muscle - continuation of the internal oblique muscle and dartos muscle - smooth muscle

Question 7

how does the scrotum and sperm link together

Answer 7

sperm production needs a temperature of about 2-3 c below core temp.In cold temperatures the cremaster and dartos muscles contract where they can absorb heat but also contraction of the dartos muscle causes the scrotum to become wrinkled, which reduces heat loss.

Question 8

What is the testes and what do they produce

Answer 8

pair of glans that sit in the scrotum,they produce sperm and testosterone which male sex hormone crucial role in reproduction and the development of secondary sexual characteristics.

Question 9

what is the seminiferous tubules testes

Answer 9

Each lobule contains one to three long, narrow tubules called seminiferous tubules.

Question 10

What is Tunica Vaginalis testes

Answer 10

Serous membrane
Derived from the peritoneum.
Partially covers the testes.

Question 11

What is Tunica albuginea testes

Answer 11

tough fibrous layer of connective tissue. Extends inward to form septa that divide the testis into 200-300 sections or lobules.

Question 12

What is sperm structure

Answer 12

Head, and a Tail.
The flattened, pointed head contains a nucleus with 23 chromosomes.
The tail is subdivided into four parts: the neck, middle piece, principal piece and end piece.

Question 13

what do Seminiferous tubules contain

Answer 13

Spermatogenic Cells - the stem and serve as the foundation for sperm forming

Leydig cells - secrete the male sex hormone testosterone lie in spaces between adjacent seminiferous tubules

Sertorli cells - supporting cells

Myoid cells - specialised smooth muscle cells

Question 14

What dies the sperm head contain

Answer 14

is covered by the acrosome which is a cap-like sac filled with enzymes that help the sperm to penetrate the ovum of the female during fertilization.

Question 16

What does the neck,middle and end piece contain

Answer 16

neck connects the head to the rest of the tail. middle piece contains mitochondria that supply the energy for the sperm’s activity.
The principal piece is the longest part. The end piece is the terminal part.

Question 17

what is the male reproductive system ducts

Answer 17

The duct system through which sperm passes after leaving the testis to reach the exterior of the body.

Question 18

what is the epididymis

Answer 18

tightly coiled single tube, located on the surface of each of the testes.Newly formed spermatozoa move from the seminiferous tubules into the epididymis,acts as a reservoir of sperm

Question 19

Where does the epididymis receives sperm

Answer 19

from the testes and passes them to the vas (ductus) deferens.

Question 20

what is the vas deferens duct

Answer 20

is a thick-wall muscular tube, which transmits sperm from the testes to the ejaculatory duct.passes through the inguinal canal into the abdominal cavity as a part of the spermatic cord

Question 21

What is seminal vesicles

Answer 21

A pair of glands situated in close proximity to the prostate gland, on either side of the bladder are sac-like structures.The fluid produced provides nourishment and fuel for the sperm and aids the movement of the sperms.

Question 22

what goes on the ejaculatory duct

Answer 22

The vas deferens travels over the top and down the back of the bladder in the abdominal cavity. It then joins with the duct from the seminal vesicle to create the ejaculatory duct. The ejaculatory duct passes through the prostate gland and opens into the urethra.

Question 23

What is the prostate gland located

Answer 23

It is situated at the base of the bladder and surrounds the urethra

Question 24

what is the function of prostate gland

Answer 24

The muscles of the prostate also ensure semen is forcefully pressed into the urethra and expelled outward during ejaculation. Produces a milky alkaline secretion which together with sperm cells from the testes and fluids from other glands make semen

Question 25

What is the bulbo - urethral glands

Answer 25

The bulbo-urethral glands are a pair of glands situated on either side of the urethra.

Question 26

What is the function of Bulbourethral glands

Answer 26

They produce a few drops of fluid upon sexual arousal, which act as a lubricant for the penis and neutralizes the acidity of the urethra prior to ejaculation.

Question 27

what is the urethra

Answer 27

A single tube originating in the bladder.Carries both urine and semen which pass through on their way through the penis to the outside of the body.

Question 28

what is semen

Answer 28

Semen is a mixture of sperms and seminal fluid.Semen is discharged from the penis during ejaculation.

Question 29

where is semen secreted

Answer 29

Seminal fluid is a thick whitish fluid consisting of fluids secreted by the seminiferous tubules, seminal vesicles, prostate gland, and bulbo-urethral glands.

Question 30

what is the penis

Answer 30

The penis is made up of a shaft that expands to form the glans, which is covered by the foreskin that folds down to form a cuff.

Question 31

what is the corpus cavernosum

Answer 31

Two dorsal masses.
Erectile tissue.
Facilitates penile erection by trapping blood within its sinuses to maintain erection until ejaculation occurs
