Testes
Genital passages accessory genital glands Penis |
|
|
Functions of the testes are?
|
spermatogenesis and testosterone secretion
|
|
|
Each testis is covered by thick fibrous capsule called?
|
tunica albuginea
|
|
|
the whole testes is covered outside its capsule by visceral layer of serous membrane called?
|
tunica vaginalis
|
|
|
Stroma is made up of
|
1. tunica albuginea
2, septula testis 3. intertubular or interstitial CT |
|
|
Parenchyma is made up of
|
Convolutede seminiferous tubules: where spermatozoa forms
|
|
|
Parenchyma is also made up of?
|
spermatogenic cells: process by which sperm cells are formed is called spermatogenesis, and is under control of FSH
|
|
|
Spermatogonia differentiate to?
|
primary spermatocytes- these are larger cells that divide by meiosis (FIRST MATURATION DIVISION)
|
|
|
Primary spermatocytes give rise to?
|
Secondary spermatocytes- cells lie closer to lumen of seminiferous tubule, they divide by meiosis(SECOND MATURATION DIVISION)
|
|
|
Secondary spermatocytes give rise to?
|
Spermatids- lie closest to lumen and are small ovoid cells- THEY CHANGE THEIR SHAPE(METAMORPHOSIS) along a series of steps.
|
|
|
Spermatozoa made up of head, neck, middle piece and tail, the head contains?
|
nucleus with 23 chromosomes
|
|
|
the heads of the spermatozoa produce an enzyme called?
|
Hyaluronidase- helps penetrate of sperm into the ovum
|
|
|
Process by which spermatogonia develop to develops to spermatids?
|
spermatocytogenesis
|
|
|
metamorphosis of spermatids to spermatozoa is?
|
spermiogenesis
|
|
|
Intersitial cells (Leidig cells) secrete what make hormone? and are _______ of ICHS of pituitary gland?
|
testosterone
under the influence |
|
|
Male genital passages are?
|
1. tubuli rectae
2. rete testis 3. ductuli efferentis 4. duct of epididymis 5. vas deferens 6. ejac duct |
|
|
Tubuli rectae
|
straight tubules, first to receive spermatozoa, lined with tall co,umnar
|
|
|
rete testis
|
irregular spaces in mediastinum testis, receive spermatozoa from tubuli rectae
simple squam to low cuboidal |
|
|
ductuli efferentis
|
receive from rete testis, alternating columnar and cuboidal, majority are ciliated
|
|
|
Duct of epididymis
|
Site of storage of spermatozoa
|
|
|
Vas deferens
|
continuation of epididymis, muscular, made up of mucosa, musculosa, adventitia
*accompanied by group structures of spermatic cord |
|
|
Ejaculatory duct
|
terminates into prostatic urethra, same structure as vas def.
|
|
|
Male genital glands consist of?
|
seminle vesicle
prostate bulbourethral gland |
|
|
Seminle vesicle
|
represent diverticual at terminal end of each vas deferens. *seminle vesicles secrete a viscid secretion rich in sugar fructose, nourishes the spermatozoa
|
|
|
Prostate
|
lies under the baldder. surrounding first part of urethra.
|
|
|
Prostate gland is made up of
|
stroma and parenchyma
|
|
|
the parenchyma of prostate is made up of
|
prostatic acini: lined with simple epithelium from cuboidal to pseudostratified.
2. ducts of prostatic acini 3. prostatic urethra |
|
|
Prostate secretes?
|
milky secretion rich in citric acid, phosphatase and proteolytic enzymes
|
|
|
Bulbourethra glands (of Cowper)

compound tubulo-alveolar glands, lie behind membranous urethra, ducts open into proximal part of penile urethra
|
|
|
Bulbourethra gland is made of ?
|
stroma and parenchyma
|
|
|
Parenchyma is composed of Acini and Ducts. The acini is lined with?
|
cuboidal to columnar epithelium secreting mucus
