Quiz 2 Flashcards
Starting with the Seminiferous tubule, what places does the sperm travel to before exiting the penis?
Seminiferous tubule, Rete testis, Efferent ducts, epididymis, vas deferens, ampulla, penal shaft
What are two functions for the spermatic cord?
- suspends the testis in the scrotum
2. Thermoregulation mechanism
Leydig cells are responsible to produce _______.
Testosterone
Sertoli cells produce _______ and _______.
Androgen binding hormone
Estrogen
Without the blood-testis barrier, what would happen?
the immune system would attach the developing germ cells as if they were foreign material to the body
True or False
As spermatozoa move down the body of the epididymis, it become more concentrated.
True
True or False Vesicular glands (seminal vesicles) are responsible to add fructose to the seminal plasma.
True
True or False
The gel fraction of seminal plasma is provided by the prostate gland.
False, cowpers gland
True or False
During the translocation of cytoplasmic droplet, as spermatozoa move through the epididymis, the cytoplasmic droplets move down the sperm tail.
True
True or False
The sperm motility decreases as we move from the head to the tail of the epididymis.
False, increases
True or False
The cremaster muscle works as a pulse pressure eliminator.
False, pampiniform plexus
True or False
Sertoli cells synthesize several hormones including androgen binding protein, and FSH.
False, not FSH
True or False
Sigmoid flexture is one of the cavernous bodies that exists in horses and sheep
False, not horses
What would happen if the pampiniform plexus was not functioning correctly? Why?
Pampiniform plexus is a thermoregulator, without this, the testis would become too warm. If the testis became too warm, spermatogenesis would not occur, thus there would be no sperm production.
What is important about the blood-testis barrier?
the blood-testis barrier keeps the immune system from attacking the developing sperm as if they were foreign material to the body
