Reproductive Anatomy Flashcards
What embryological layer is the reproductive system derived from
mesoderm
What structures arise from the mesonphrenic (Wolffian) duct (SEED)
Seminal vesicle, Epididymis, Ejaculatory duct, and Ducuts deferens (SEED)
Where are spermatozoa produced and influences production
seminal vesicle and testosterone
Which cells secrete testosterone and what promotes secretion
interstitial cells of (L)eydig under the influence of (L)eutenizing hormone
What is the thick fibrous capsule called which surrounds the testis
tunica albuginea
Straigt tubules join together to form this
rete testis
Name the seven layers of the testes
skin, dartos muscle with colles fascia, external spermatic fascia, cremasteric muscle, internal spermatic fascia, parietal layer of tunica vaginalis, and visceral layer of tunica vaginalis
Where do sperm matuer
epididymus
Where are sperm stored
ducuts deferens
What structures form the ejaculatory duct
terminal end of ductus deferens and seminal duct
What are the coverings, arteries, nerves, and other structures of the spermatic cord (3s)
3 coverings: external spermatic fascia, cremasteric muscle and fascia, and internal spermatic fascia
3 arteries: testicular artery, artery to the ductus deferens, and cremasteric artery
3 nerves: testicular nerves, gental branch of the genitofermoral nerve, and ilioinguinal nerve (actually lies outside)
3 other structures: ductus deferens, pampiniform plexus of veins and testicular lymphatics,
Name the compartments of the penis
2 dorsal corpora cavernosa and a single inferior corpus spongiosum
What are the corpora enclosed in
fibrous sheath called Buck’s fascia
Blood supply of the penis
deep penile and dorsal penile branches of the internal pudendal artery
Innervation of the penis
penile branches of the pudendal nerve and branches of the pelvic splanchnic nerves both from S2, 3, and 4 (keeps the penis off the floor)
Stimulation of which nervous system is responsible for erections
(p)arasympathetic (p)oint
Stimulation of which nervous system is responsible for ejaculation
(s)ympathetic (s)hoot
What is the hair bearing fat bad of the female genitalia
mons pubis
The lateral portion of the labia minora fuses above the clitoris forming this
prepuce
the medial parts of the labia manora fuses below the clitoris forming this
frenulum
Where does the vagina mainly develop from
urogenital sinus
What is the normal positioning of the uterus
ante(v)erted - angled forwards to the (v)agina and antefle(x)ed - body is fowards to cervi(x)
What attaches the uterus to the ovary
ligament of the ovary
what attaches the uterus to the labia majora
round ligament of the uterus and the broad ligament
What are fallopian tubes lined with
ciliated columnar epithelium
what are the 4 parts of the fallopian tubes
infundibulum, ampulla (fertilization takes place), isthmus, an intramural
Where do the veins of the ovaries drain
right ovarian vein into the inferior vena cava and left ovarian vein into the left renal vein
What ligaments are contained within the broad ligament
ligament of the ovary and round ligament of the uterus
what part of the broad ligament contains the uterine tube
mesosalpinx
What bones make up the pelvis
os coxae, sacrum, and coccyx
What bones form the os coxae and where doe they fuse
ilium, ischium, and pubis and they fuse in the acetabulum
In what ways is the male pelvis different from the female pelvis
heavier with more prominant muscular markings
smaller heart-shaped pelvic inlet
subpubic angle is narrower (45 degrees in males 85 female)
ischial spines are inverted
sacrum is more curved
