4 Male & Female Reproduction Flashcards
What are the principle cells found in the supporting tissues between the seminiferous tubules of the testes?
Leydig Cells
Testosterone is the main hormone secreted by what cells within the testis?
Leydig Cells
Where are the Leydig cells found?
The interstitium, around the seminiferous tubules
How are the seratoli cells of the testis bound to one another?
Tight junctions
The parietal layer of the testis is known as the:
Tunica Vaginalis
The visceral layer (nearest the seminiferous tubules) of the Tunica Vaginalis is known as:
Tunica Albuginea
The Ductus Deferens (epididymis) receives sperm from the seminiferous tubules via a plexus known as the:
Rete Testes
Which class of the germ cells lining the seminiferous tubules go on to become sperm, type A or B?
Type B
Within the seminiferous tubules of the testis, maintenance of the germ cell pool is carried out by which cells?
Spermatogonia Type A
What is the name of the process by which sperm become motile?
Spermiogenesis
During spermiogenesis, the golgi apapratus elaborates a structure which will eventually cap the nucleus - this is known as:
Acrosomal Vesicle
What cellular organelles are found in abundance in the midpiece of a sperm cell?
Mitochondria
Cells expressing stereocilia are found in what structure of the male testis?
Epididymis
In what structure of the testes do the sperm become mature?
In the epididymis
The majority of ejaculate is secreted by the seminal vesicle, or by the prostate gland?
Seminal Vesicle
