3 Reproductive Anatomy Flashcards
What separates the greater and lesser pelvis?
the pelvic inlet
What muscle group suppoerts the pelvic diaphragm?
levator ani
What is the pathway of the Ductus defferens?
begins from inferior pole on medial side of testes
travels through inguinal canal
goes on postero - medial aspect of the bladder
then joins with its’ duct
What is the function of the ductus deferens?
carries the sperms for the ejaculations
Where is the ejaculatory duct and what does it open into?
prostate
opens into the seminal colliculus
Where is the seminal vesicle?
between the bladder and the rectum
What does the seminal vesicle do?
secretes alkaline fluid fructose fibrinogen vitamin C prostoglandins
comprises 50-70% of semen
What does the prostate secrete?
milky thin stuff rich in proteolytic enzymes, fibrinolysis, and citric acid
30-50% of semen
Where is the bulbourethral gland?
within the external urethral sphincter muscle
What is erectile tissue called?
corposa cavernosa and corpus spongiosum
What innervates the penis?
pudendal nerves (sensory and sympathetic) pelvic splanchnic nerves (parasympathetic)
What innervates the scrotum?
anterior and posterior scrotal nerves
What type of muscle is in the scrotum?
dartos muscle
What lines the ovaries?
germinal epithlium
What ligaments are associated with the ovaries?
suspensory
ovarian
borad
What supplies the ovaries?
ovarian arteries
What are the different areas of the uterine tubes?
uterine
isthmus
ampulla region
fimbriae
What is the most common site for fertilisation?
ampulla region of the uterin tube
What supplies the uterine tubes?
ovarian and uterine arteries
What dictates the orientation of the uterus?
anteversion (between vagina and cervix 90 degrees)
anteflexion (170 degrees)
What ligaments are associated with the uterus?
ligament of ovary
round ligament of uterus
broad ligament of uterus
What ligaments are associated with the cervix?
cardinal / transverse cervical ligament
uterosacral ligament

What comprises the vulva?
labia majora
libia minora
clitoris
What are Bartholin glands?
vestibular glands (urethra, vagina, and ducts of vestibular glands) vestibular glands secrete mucous
What supplies the vulva?
external and internal pudendal arteries
What drains the vulva
pudendal vein
What innervates the vulva?
anterior labial nerves
posteirior labial nerves
posterior cutaneous nerve
parasympathetic fibres for erectile tissue
What are the coverings of the testes?
tunica vaginalis (visceral and parietal layers) tunica albuginea (deeper, tougher fibrous layer)
What does the tunica albuginea do?
separates the testes into lobules
What are within the testicular lobules?
seminiferous tubules for spermatic maturation
What o seminiferous tubes drain into?
rate testes and then epididymis
What are the contents of the spermatic chords?
vas deferens
testicular artery
pampiform venous venous plexus
Lymph draining into lumbar and pre-aortic nodes
What 3 muscles comprise levator ani?
puborectalis
pubococcygeus
iliococcygeus
What 2 triangles comprise the pelvic diaphragm?
urogenital triangle
anal triangle
What are the common contents of the superficial perineal pouches?
superficial transverse perineal muscle
deep perineal branches of internal pudendal vessels and pudendal nerves
What are the male specific contents of the superficial perineal pouches?
root of the penis and ischiocavernosus and bulbospongiosus
proximal spongy urethra
What are the female specific contents of the superficial perineal pouches?
clitoris and ischiovernosus
bulbs of vestibule and bulbospongiosusgreater vestibular glands
What are the common deep perineal pouch contents?
inferior part of external urethral sphincter
dorsal neurovascular structures for erectile tissues
anterior extensions of ischio-anal fat pads
What are the male specific contents of the deep perineal pouch contents?
intermmediate part of the urethra
deep transverse perineal muscles
bulbourethral glands
What are the female specific contents of the deep perineal pouches?
part of vagina and urethra
mass of smooth muscle in the place of deep transverse perineal muscles
