(Anatomy and Physiology) Reproductive System Flashcards
In the anatomy of the male reproductive system, what does it make and do?
Creates sperm cells
Has the means to deliver them to the female’s reproductive tract
What does the male reproductive system anatomy include?
Includes the output of both organs and structures
Describe:
Testes (2)
Situated outside the abdomen in the male
Housed in a skin-covered bag called the scrotum
What is the singular form of testes?
Testis
What is the skin-covered bag that contains the testes called?
Scrotum
What covers the scrotum? Where does it come from?
The peritoneum, extending from within the abdomen
What allows the testes to be drawn closer to the abdomen? Where is it located?
The cremaster muscle
Within the scrotum wall
What does the cremaster muscle allow?
Allows the testes to be drawn closer to the abdomen
True or False:
Scrotal temperature must be higher than body temperature in order for sperm production to occur optimally
False, scrotal temperature must be LOWER than body temperature in order for sperm production to occur optimally
The testes conform closely to the __________
Epididymis
Describe:
Epididymis
A long (highly folded) tube that is connected to the teste’s outer surface
What does the epididymis do? (2)
Acts as a storage area within the testes for the sperm produced
The sperm goes through their final maturation in here
Why does the sperm go through their final maturation in the epididymis?
This final development is required before the sperm can fertilize an egg
The sperm cord contains: (3)
The artery
The vein
The nerve of the testicular
The source of arterial blood originates from the _______ descending _____
Abdomen
Aorta
Besides the _____ vessels, there is also the ______ ________ in the _____ cord
Blood
Ductus deferens
Sperm
The sperm cord reaches the abdomen through a slit called and situated in:
Injuinal canal
Muscles of the abdomen
What do the tissues on either side of the inguinal canal do? (2)
Are in close contact with each other
Provide a possible gap through which other structures can protrude
Describe:
Ductus deferens
Carries sperm to the prostate gland from the epididymis
Like many other tubular structures, the ductus deferens has a _______ muscle wall that enables the ______ cells to be transported __________ by ___________
Smooth
Sperm
Physically
Peristalsis
Where is the prostate gland found?
Around the urethra at the base of the urinary bladder
True or False:
The prostate is a dog’s supplementary sex organ
False, the prostate is the dog’s ONLY supplementary sex organ
Where does ductus deferens enter in the prostate?
Enters the urethra in the prostate
The prostate-produced secretions are important for what?
The sperm’s survival and motility
