Reproductive Anatomy Flashcards
5 layers of penis (from superficial to deep)
- outer dermis
- Superficial (dartos) fascia
- deep (Buck’s) fascia
- tunica albuginea (encases erectile tissue and separates corpora cavernosa from corpora spongisum)
5 urethra
what structure does the male urethra run through
corpus spongiosum
pathway of sperm during ejaculation (6)
- Seminiferous tubules
- Epididymis
- Vas deferens
- Ejaculatory ducts
- Urethra
- Penis
which nerve is responsible for erection? what branch of NS
Pelvic n.–> parasympathetic
what substance is proerectile? which is antierectile?
- NO–> increases cGMP –> SM relaxation and vasodilation
2. NE–> increases intracell Ca–> SM contraction/ vasoconstriction
what is emission
when sperm moves from testes to prostatic urethra to mix with seminal fluid
what nerve is responsible for emission? branch of NS
- hypogastric n.–> sympathetic
what nerve responsible for ejaculation/ what branch of NS
- Pudendal n.–> visceral and somatic nerves
connects cervix to side wall of pelvis
Cardinal ligament
connects ovaries to lateral pelvic wall
suspensory ligament of ovaries (infundibulopelvic ligament)
contains ovaries, fallopian tubes, and round ligament of ovaries
Broad ligament
connects medial pole of ovary to lateral uterus
Ligament of the ovary
contains ovarian vessels
Suspensory ligament of the ovaries (infundibulopelvic ligament)
contains uterine vessels
Cardinal ligament
3 pudendal nerve branches
- inferior rectal nerve
- Dorsal nerve of penis (or clitoris)
- Perineal nerves
