Flashcards in Male reproductive system histology Deck (39):
What is the endocrine function of the the testes?
What is the exocrine function of the testes?
Spermiogenisis is what part of the process?
The maturation process
Spermatocytogenisis refers to what?
Formation of the spermatogonia
Spermatogonial phase is related to what?
The spermatocyte phase is related to what?
The temperature in the scrotum needs to be ____ degrees. Why?
34 degrees celsius. This is the required temperature for sperm production
T/F there are different lobules in the testes?
True- each lobule contains seminiferous tubules
Which cells produce testosterone?
The leydig cells
The straight tubule is also called what?
What houses the rete testis?
the mediastinum of the testes
What types of cells are found in the seminiferous tubules?
The seminiferous tubules are line with what type of cells?
Complex stratified epithelium
What is the role of the sertoli cells?
Support- create a physical barrier- a blood testes barrier
Spermatogonia are the most _______ of the cells.
In the seminiferous tubes, where will spermatogonia be found?
Around the outside- the more mature the cell, the further it moves towards the center
Type A dark spermatogonia give rise to what?
More type A dark as well as type A pale spermatogonia
T/F type A pale spermatogonia are dedicated to move on
What type of division do type A and B go through?
What are the cells called sitting on the basal layer (the outside with cells growing inward)?
Spermatogonia (the most immature cells)
Type A pale and Type B spermatogonia begin to divide, what type of division is seen?
When the cells go through meiosis 1, what are they called?
Once the cell is going through meiosis 2, what is it called?
Secondary spermatocyte (won't see these)
Once meiosis 2 is finished, what is the cell called and where is it found?
spermatids- found towards the lumen (the center)
Straight tubules are lined with which cells?
What is the rete testis?
interconnected network of channels lined with cuboidal/columnar epithelium with cilium and a few microvilli
What are the three excretory ducts?
Ductus deferens/vas deferens
What are the three parts/divisions of the urethra?
There are three male accessory glands- what are they?
The seminal vesicles
The prostate gland
The bulbourethral glands
What do the male accessory glands produce?
What is seminal fluid?
It is the medium in which the sperm leave the male body
What is the shape of the nucleus of a sertoli cell?
The seminal vesicles connect with what to form the ejaculatory duct?
the vas deferens (ductus deferens)
T/F The prostate gland is a collection of 30-50 tubuloalveolar glands.
From outside to inside, what are the levels of cells in the seminiferous tubules
Spermatogonia (type A and B- found on the outside)
The prostate gland empties into what?
The prostatic urethra
What is the flow of the spermatocyte?
Starts in the seminiferous tubules, goes to the straight tubules, to the rete testes, to the efferent ductules- to the epididymis- to the ductus deferens- to the ejaculatory duct to the urethra and out
The bulbourethral glands (cowper's glands) empty into what?
The proximal part of the penile urethra
