histology of reproductive system Flashcards
testis is made up
capsule septa reticular connective tissue
capsule of the testis
3 layers
- tunica vaginalis is simple squamous mesothelium
formed of inner ( visceral ) and outer (parietal ) layer - tunica albuginea under tunica vaginalis is collagenous
fibres , thick posterior to form mediastinum of testis - tunica vasculosa under tunica albuginea is CT, rich in
blood capillaries
septa of the testis
Is connective tissue fibers from tunica albuginea extend to testis to divided the testis into 250 lobules each lobule contains 1 to 4 seminiferous tubules
reticular tissue of the testis
is connective fibers and cells which form testicular lobules (parenchyma of testis )
basement membrane surrounding seminiferous tubules
is made up of connective tissue and smooth cells
cells of the seminiferous tubules
two types
spermatogenic sertoli cells
interstitial cells cells of leydig
formation of sperm
spermatogonia type A ( stem cells) spermatogonia types B primary spermatocytes secondary sprmatocytes spermatid sperm or spermatozoa
simple columnar cells between spermatogenic cells
sertoli cells
function of sertoli
nutrition support phagocytic cell
form blood testis barrier secretes inhibitor hormones which inhibit FSH , so control spermatogenesis
secretes testicular fluid rich in androgen binding protein (ABP ) which promotes action of testestrone and FSH
controls spermatogenesis
FSH
promotes action of testestrone and FSH
androgen binding protein (ABP )
outside the tubules secretes testosterone
leydig cells
genital ducts consist of
intra testicular ducts
extra testicular ducts
intra testicular ducts consist of
tubuli recti and rete testis
extra testicular ducts consist of
vasa efferentia epididymis vas deferens ejaculatory duct male urethra
tubuli recti is made up of
simple columnar cells from seminiferous tubules to rete testis
rete testis is made up of
simple cuboid cells from rete testis to vasa efferentia
vasa efferentia is made up of
columnar ciliated cell and few cells is non ciliated from rete testis to epididymis
epididymis is made up of
pseudo-stratified columnar ciliated epithelium but cilia non mobile (sterocilia) from vasa efferentia to vas deferen
vas deferens is made up of
mucosa epithelium
pseudo-stratified columnar ciliated epithelium but cilia non mobile
but the upper part is pseudo-stratified columnar non ciliated epithelium and connective tissue
musculosa is smooth muscles inner and outer longitudinal and middle circular
adventitia is connective tissue
ejaculatory duct is made up of
vas deferens and seminal vesicle line by simple columnar or pseudo-stratified columnar
seminal vesicles is made up of
tubular gland formed of
mucosa formed by columnar cells connective tissue smooth muscles and elastic fibers
mucosal formed of inner circular and outer longitudinal smooth muscles
adventitia formed of connective tissue
prostate is made up of
tubuio-alveolar gland formed by
capsule : is connective tissue and smooth muscles
septa : is fibro-muscular septa extend from capsule to divided the glang into lobules
parenchyma : formed of glands
penis is made up of
formed by
two corpus cavernosa and one corpus spongiosum
each corpus formed of blood space smooth muscles collagenous and elastic fibres
covered by tunica albuginea fascia of penis and skin
ovaries is made of
covered by
germinal epithelium
which in young female is simple cuboid
in old female is simple squamous
tunica albuginea inside germinal epithelium is connective tissue
ovaries divided into outer cortex and central medulla
central medulla of ovaries is made up of
is connective tissue and contains elastic fibers smooth muscles spiral arteries and veins
outer cortex of ovaries is made up of
contain interstitial cells and ovarian follicles
interstitial cells
ovarian follicles is follicular cells surround oocyte
interstitial cells of the outer cortex of the ovaries secret
androgen (estrogen and progestrone )
primordial follicles is primary oocyte surround by
simple squamous follicular cells
primary follicles is primary oocyte surround by
cuboid cells then columnar cells
growing oocyte
secondary follicles
secondary follicles oocyte
becomes large which surround by glycoprotein membrane (zona pellucid) and surround by granulosa cells (proliferated columnar follicular cells) which secretes follicular fluid which form cavities between granulosa cells ,the follicle from outside
glycoprotein membrane
zona pellucida
granulosa cells
proliferated columnar follicular cells
secretes follicular fluid which forms cavities between granulosa cells the follicle from outside
granulosa cells
nutritional cells of developing cell
theca externa
secretes oestrogen from developing cell
theca interna
mature graafian follicles formed by
theca cells basement membrane granulose cells follicular cells and secondary oocyte from outside inside
development of ova
oogonia primary oocytes secondary oocytes ova
uterine tube is made up of
mucosa is simple columnar partial ciliated and partial secretory
submucosa is connective tissue rich in blood capillary
musculosa is inner circular and outer longitudinal smooth muscles
serosa is connective tissue and simple squamous epithelium
body of uterus is made up of
endometrium myometrium and perimetrium from inside out
the endometrium of the uterus is made up of
epithelium : simple columnar ciliated and non ciliated secretory in function
uterine gland : which is tubular gland and CT contain blood vessels and phagocytic cells and decidual cells
endometrium divided into
superficial functional layer and deep basal layer
the myometrium of the uterus is made up of
smooth muscles which are longitudinal and oblique smooth muscles between them are blood vessels
perimetrium of the uterus is made up of
is connective tissue and blood vessels and cover by simple squamous epithelium
cervix of the uterus is made up of
fibers tissues with few smooth muscles
cervical canal
internal os line by simple columnar epithelium
external os is stratifed squamous epithelium
Under epithelium are tubulo-alveolar gland s
vagina is made up of
mucosa line with non-keratinising stratified squamous epithelium connective tissue in blood vessels and elastic fibers no glands
musculosa is inner circular and outer longitudinal smooth muscles
adventiais is connective tissue
