male and female genitalia Flashcards
primary sex organs
gonads
male gonads
testes
female gonads
ovaries
function of gonads
responsible for producing the sperm and ova but they also secrete hormones and are considered to be endocrine glands
sex cells
gametes
gamete sex cells in males
sperm
gamete sex cells in woman
ovum ova egg
accessory sex organs
internal glands and ducts and the external genitalia
internal organs of male reproductive system include
testis ductus deferens (vas deferens ) seminal vesicles ejaculatory ducts prostatic glands bulborethrala glands
external organs of male reproductive system include
scrotum and penis
wall of scrotum consists of
dermisdartos muscle and cremaster muscle
wrinkling of skin
dermisdartos muscle
contract based on temperature
cremaster muscle
inside the scrotum consists of
tunica vaginalis and tunica albuginea
serous covering of the testis
tunica vaginalis
tunica albuginea
fibrous envelope that extends the length of the corpora cavernosa penis (containing erectile tissue) and corpus spongiosum penis (containing the male urethra). It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer
blood supply of the scrotum
anterior scrotal arteries
posterior scrotal arteries
cremasteric arteries
venous drainage of the scortum
scrotal veins
lymphatic drainage of scrotum
superficial inguinal nodes
innervation of scortum
anterior scrotal nerves
the genital branch of the genitofemoral nerve
posterior scrotal nerves
perineal branch of the posterior femoral cutaneous nerve
erectile spongy tissue of the penis
corpus cavernosum and corpus spongiosum
urethra passes through
corpus spongiosum
rounded head (or tip) of the penis
glans penis
sperm passes through
urethra
testis
produce both sperm and androgens, primarily testosterone
testis contain
spermatic cord seminiferous tubule efferent ductule epididymis vas deferens tunica albuginea tunica vaginalis cavity of tunica albuginea
divisions of epididymis
head body and tail
cord-like structure in males formed by the vas deferens
spermatic cord
site of spermatogenesis where germ cells develop into spermatozoa in close interaction with sertoli cells
seminiferous tubule
series of parallel thin, delicate tubules that connect the rete testis to a single tub of the epididymis
efferent ductule
a highly convoluted duct behind the testis, along which sperm passes to the vas deferens
epididymis
the duct which conveys sperm from the testicle to the urethra
vas deferens
enlargement of the ductus deferens at the fundus of the bladder which acts as a reservoir for sperm
ampulla of vas deferens
arterial supply of vas deferens
superior vesical artery and testicular artery
venous drainage of vas deferens
testicular vein and paminiform plexus
lymph drainage of vas deferens
external iliac nodes
form a short ejaculatory duct
each ductus deferens joins the duct from the adjacent seminal vesicle
ejaculatory duct passes through
the prostate gland and empties into urethra
arterial supply of ejaculatory duct
superior vesical arteries
venous drainage of ejaculatory duct
prostatic and vesical venous plexuses
lymph drainage of ejaculatory duct
external iliac nodes
function of accessory glands
secrete fluids that enter the urethra
accessory glands include
seminal vesicles
prostatic gland
bulbourethral gland
seminal vesicles
secret fluid which is viscous and contains fructose prostaglandins and proteins
arterial supply of seminal vesicle
inferior vesicle and middle rectal arteries venous drainage is same
lymph drainage of seminal vesicle
external iliac nodes for superior
internal iliac nodes for inferior
prostate
dense structure that encircles the urethra as it leaves the urinary bladder secretions of the prostate are thin, milky colored, and alkaline function to enhance the motility of the sperm
arterial supply of prostate
prostatic arteries branches of interal iliac artery
inferior vesical arteries
internal pudendal artery
middle rectal artery
venous drainage of prostate
prostatic venous plexus drains into internal iliac veins
lymph drainage of prostate
internal iliac lymph nodes some drain into sacral nodes
bulborethral gland
also known as cowpers gland located at the base of the penis enters the penile urethra
in response to sexual stimulation bulboetheral gland secrets
alkaline mucus like fluid
accessory sex organs of the female include
uterine tube uterus vagina vulva
where do the ovaries lie
in the ovarian fossa in the lateral wall of the pelvis invested by double fold of peritoneum called mesovarium
primary female sex organ
ovaries
relations of the ovaries
lies between bifurcation of common iliac vessels on the obturater nerve
ureter relation to ovaries
posterolteral to the ovary
separate ovaries and thinnest part of acetabulum
obturater internus and its fascia
ligaments of the ovaries
round ligament and suspensory ligament
connect the ovaries and uterus
uterine tube
receive the ovulated egg and site of fertilisation
uterine tube
parts of the uterine tube
infundibulum ampulla isthmus (closes to uterus) interstitial segment
regions of uterus
funds body cervix
support of the uterus includes
pelvic floor muscle
round ligaments
transverse cervical ligaments
uterosacral ligaments
pelvic floor muscle
pelvic diaphragm urogenital diaphragm
round ligament pathway
lateral uterus through inguinal canal to labia majora
maintain anteverted position
round ligaments
transverse cervical ligaments pathway
lateral cervix and vagina to pelvic wall
uterosacral ligaments pathway
Inferior uterus to sacrum
lymph vessels from the fundus drain into the
para-aortic nodes
lymph vessels from the body and cervix drain into the
internal and external iliac lymph nodes
lymph vessels from the round ligament of the uterus
superficial inguinal lymph nodes
length of vagina
3 - 4 cm
located under prepuce
clitoris
clitoris contains
shaft and glands
