Answer 2

Seminal vesicle
Epididymis
Ejaculatory duct
Ductus deferens

Question 3

What do the testes develop from

Answer 3

mesoderm (which lie on top of kidney)

Question 4

What develops from the paramesonephric (mullerian) duct

Answer 4

Uterus
Upper 1/3 of vag

Question 5

Where is spermatozoa produced

Answer 5

seminiferous tubules (under influence of test)

Question 6

What is test secreted by (+ what influences it)

Answer 6

Secreted by the interstitial cells of leydig (under influence of luteinizing hormone)

-test is attached to sertoli cells found in the tubules of the testis

Question 7

make up + emptying route of the testes

Answer 7

300 lobules each containing 1-4 seminiferous tibules

semineferous tubules drain into 25 straight tubules which join to form the rate testis which empty into the epididymis via 15-20 efferent ductules

Answer 8

Skin
Dartos mm
External spermatic fascia
cremasteric mm
internal spermatic fascia
parietal and visceral layers of tunica vaginalis

Question 9

where does sperm mature

Answer 9

epididymis

Question 10

where are sperm matured

Answer 10

ductus deferens

Question 11

What makes up the ejaculatory duct

Answer 11

the ductus deferent is joined at its terminal end by the seminal duct forming the ejaculatory duct

Question 12

what are the 3 coverings of the spermatic cord

Answer 12

external spematic fascia
cremmasteric mm/fasica
internal spematic fascia

Question 13

3 arteries, 3 nerves and 3 other structures that travel in spermatic cord

Answer 13

3 arteries- testicular, artery to ductus deferens and cremasteric

3 nerves- testicular, genital branch of genitofemoral n, ilioinguinal nerve(actually outside)

3 others- ductus deferens, pam-uniform plexus of veins, testicular lymphatics

Question 14

makeup of penis

Answer 14

two dorsally located blood filled corpora cavernosa and single inferiorly located corpus spongiosum (enclosed in Bucks Fascia)

Question 15

What supplies the penis (arteries-2)

Answer 15

deep penile branch + dorsal penile branch of internal pudendal aa

Question 16

What inn the penis

Answer 16

Penile branches of pudendal nerve
branches of pelvic splanchnic nerve
(both from S2,3,4 -keep penis off floor)

Anteverted (angled towards vag) and anti flexed (body is bent forward to cervix)

Question 19

What attaches the uterus ti the very and labia major

Answer 19

Ovary- by lig of ovary

Labia major- round lig of uterus and to broad lig

Question 20

uterus and upper vag are supplied by what artery

Answer 20

respective named branches of the ant div of the internal iliac aa

4 parts of the fallopian tubes (+ what are they made of)

Answer 21

ciliated columnar epithelium

1. infundibulum
2. ampulla
3. narrow isthmus
4. intramural part

Answer 23

-post aspect of the broad lig by mesovarium
-suspensory lig to pelvic wall
-lig of ovary to uterus

Question 24

What artery supplies the ovary

Answer 24

ovarian artery (branch of the abdominal aorta at L2)

Question 25

where does the right and left ovarian veins drain

Answer 25

left- inf vena cava
right- left renal vein

Answer 26

lig of ovary
round lig of the uterus

Question 27

How is the male pelvis different from the female

Answer 27
