Male Repro

Question 1

trace path sperm

Answer 1

1. seminiferous tubules of testes
2. epididymis
3. ductus deferens
4. ejaculatory duct
5. prostatic urethra
6. membranous urethra
7. spongy urethra
8. external urethral orifice

Question 2

functional roles of sertoli cells of testes

Answer 2

support process of spermatogenesis and spermiogenesis, produce the hormone inhibin

Question 3

functional role of interstitial (leydig) cells of testis

Answer 3

produce male sex steriod hormones (ex: androgens such as testosterone)

Question 4

why would a male with situs inversus have difficulty conceiving a child

Answer 4

flagella in sperm would be defective

Question 5

what is the anatomy/function of the seminal vesicels

Answer 5

accessory glands of the male repro system

pair of contorted tubes located between bladder and rectum

combines with vas deferens to form the ejaculatory duct

Funciton

• contribute 85% of seminal fluid
• important in sperm motility,

Question 6

what is PSA + functions

Answer 6

prostate specific antigen

protein produced by cells of the prostate gland

PSA functions to liquefy the ejaculate and aids in sperm motility

Question 7

PSA levels

Answer 7

elevated PSA with prostatitis, benign prostate hyperplasia, prostate cancer

PSA levels ARE NOT diagnostic between hyperplasia and cancer

Question 8

what is the anatomical relationships of the prostate

aka what borders it anteriorly, posteriorly, superiorly, inferiorly and laterally

Answer 8

anterior: pubic symphysis (inferior part)
posterior: ampulla of rectum
superior: urinary bladder, seminal vesicles, ampulla of ductus deferens
inferior: urethral sphincter, DEEP PERINEAL MUSCLES
lateral: LEAVATOR ANI MUSCLE

Question 9

what are the 4 zones of the prostate

Answer 9

1. peripheral zone
2. central zone
3. transitional zone
4. anterior fibromuscular zone (anterior muscular zone)

Question 10

what does the anterior fibromuscular zone of the prostate consist of

Answer 10

smooth muscle to help expel prostatic fluid

Question 11

where do most prostate cancers develop

Answer 11

in the peripheral and central zones

Question 12

what does the penis consist of?

Answer 12

the root, body, and glans

Question 13

what are the two erectile tissues

Answer 13

corpus spongiosum

corpora cavernosa

Question 14

what does the root of the penis attach to

Answer 14

?

Question 15

What does the root of the penis consist of

Answer 15

consists of
crura,
bulb of penis
, and ischiocavernosus muscle and bulbospongiosus muscle

located in the superficial perineal pouch

Question 16

How are the two erectile tissues arranged within the root of the penis

Answer 16

crura: consists of corpora cavernosa and attaches to the inferior surface of the ischial ramus
bulb: corpus songiosum

Question 17

What does the body of the penis consist of

how are the erectile tissues arranged

Answer 17

no muscles

two corpora cavernosa form the dorsal aspect of penis

single corpora spongiosum forms urethral surface of the penis

Question 18

what is the glans penis and what type of erectile tissue

Answer 18

distal end of penis formed by corpus spongiosum

Question 19

Epispadias

Answer 19

Epispadias is a rare birth defect located at the opening of the urethra.

In this condition, the urethra does not develop into a full tube, and the urine exits the body from an abnormal location.

Along the top of the penis?

Question 20

Hypospadias

Answer 20

is a birth defect in boys where the opening of the urethra (the tube that carries urine from the bladder to the outside of the body) is not located at the tip of the penis.

Along the bottom of the penis

Question 21

Peyronie’s disease

Answer 21

Aka penile fibrosis

disease is a noncancerous condition resulting from fibrous scar tissue that develops on the penis and causes curved, painful erections.

Question 22

diphallia

Answer 22

Diphallia is a genetic condition present at birth in which a person has two penises.

Question 23

phimosis

Answer 23

Phimosis is a condition where the foreskin is too tight to be pulled back over the head of the penis (glans).

Phimosis is normal in babies and toddlers, but in older children it may be the result of a skin condition that has caused scarring. It is not usually a problem unless it causes symptoms.

Question 24

Paraphimosis

Answer 24

paraphimosis is a urologic emergency, occurring in uncircumcised males, in which the foreskin becomes trapped behind the corona and forms a tight band of constricting tissue.

Often iatrogenically induced,
