General Anatomy- Reproductive Anatomy Flashcards
What part of the embryo is the reproductive system from
derived by the mesoderm
what arises from the mesonephric (wolffien duct)
Seminal vesicle
Epididymis
Ejaculatory duct
Ductus deferens
What do the testes develop from
mesoderm (which lie on top of kidney)
What develops from the paramesonephric (mullerian) duct
Uterus
Upper 1/3 of vag
Where is spermatozoa produced
seminiferous tubules (under influence of test)
What is test secreted by (+ what influences it)
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
make up + emptying route of the testes
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
what are the 7 layers that cover testes from out to in
Skin
Dartos mm
External spermatic fascia
cremasteric mm
internal spermatic fascia
parietal and visceral layers of tunica vaginalis
where does sperm mature
epididymis
where are sperm matured
ductus deferens
What makes up the ejaculatory duct
the ductus deferent is joined at its terminal end by the seminal duct forming the ejaculatory duct
what are the 3 coverings of the spermatic cord
external spematic fascia
cremmasteric mm/fasica
internal spematic fascia
3 arteries, 3 nerves and 3 other structures that travel in spermatic cord
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
makeup of penis
two dorsally located blood filled corpora cavernosa and single inferiorly located corpus spongiosum (enclosed in Bucks Fascia)
What supplies the penis (arteries-2)
deep penile branch + dorsal penile branch of internal pudendal aa
What inn the penis
Penile branches of pudendal nerve
branches of pelvic splanchnic nerve
(both from S2,3,4 -keep penis off floor)
Urethra location in girls
anterior to rectum and post to vag
typical location of the uterus
Anteverted (angled towards vag) and anti flexed (body is bent forward to cervix)
What attaches the uterus ti the very and labia major
Ovary- by lig of ovary
Labia major- round lig of uterus and to broad lig
uterus and upper vag are supplied by what artery
respective named branches of the ant div of the internal iliac aa
4 parts of the fallopian tubes (+ what are they made of)
ciliated columnar epithelium
- infundibulum
- ampulla
- narrow isthmus
- intramural part
Where does the overies lie
in ovarian fossa between the external and internal iliac arteries
how is the ovary attached (3)
-post aspect of the broad lig by mesovarium
-suspensory lig to pelvic wall
-lig of ovary to uterus
What artery supplies the ovary
ovarian artery (branch of the abdominal aorta at L2)
where does the right and left ovarian veins drain
left- inf vena cava
right- left renal vein
what does the broad ligament contain
lig of ovary
round lig of the uterus
How is the male pelvis different from the female
-heavier and more prominent mm markings
-smaller heart shaped pelvic inlet
-suprapubic angle is narrow (45 vs 85)
-inverted ischial spines
-sacrum more curved
