Male Reproductive System Flashcards
(37 cards)
What is the function of the acrosome in spermatozoa?
It contains enzymes that help the sperm penetrate the outer layers of the egg during fertilization.
Q: How long can spermatozoa survive in the female reproductive tract?
Several days, depending on conditions.
What do seminal vesicles contribute to semen?
They produce a fluid rich in sugars that nourishes sperm.
What are the three main parts of a spermatozoon?
Head, midpiece, and tail (flagellum).
What are spermatozoa?
The mature male gametes (sperm) involved in fertilization.
What is spermatogenesis?
The process of sperm production that occurs in the seminiferous tubules
What is the function of Sertoli cells in the seminiferous tubules?
They support and nourish developing sperm cells and create a blood-testis barrier.
What do Leydig cells produce?
Testosterone, the main male sex hormone.
What role does the epididymis play in the male reproductive system?
It stores and matures sperm produced in the testes.
What are the testes responsible for?
Producing sperm (spermatogenesis) and testosterone
What is the function of the scrotum?
It holds the testes outside the body to regulate their temperature for optimal sperm production.
What is the primary function of the male reproductive system?
To produce sperm and hormones, primarily testosterone.
What is the role of the prostate gland?
It produces a fluid that nourishes and protects sperm, and it helps to form part of the semen.
What is the primary function of the male reproductive system?
To produce sperm and hormones, primarily testosterone.
What are seminiferous tubules?
Coiled structures within the testes where spermatogenesis (sperm production) occurs.
What is the vas deferens?
A muscular tube that transports sperm from the epididymis to the ejaculatory duct.
What are bulbourethral glands?
Glands that secrete a pre-ejaculatory fluid that lubricates the urethra and neutralizes acidity.
What are seminal vesicles?
Glands that produce a fluid rich in fructose, which nourishes sperm and forms a significant portion of semen.
What is the urethra?
A tube that carries urine from the bladder and semen from the reproductive system out of the body through the penis.
What is the penis?
The external organ that delivers sperm to the female reproductive system and expels urine from the body.
Describe the pathway of sperm from production to ejaculation.
Sperm are produced in the testes, mature in the epididymis, travel through the vas deferens, mix with seminal fluid from the seminal vesicles and prostate gland, and are expelled through the urethra during ejaculation.
What is the primary role of testosterone in males?
It is responsible for the development of male secondary sexual characteristics, such as facial hair, deep voice, and muscle growth.
Which hormones regulate the male reproductive system?
Testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).
What is the function of the acrosome in spermatozoa?
It contains enzymes that help the sperm penetrate the outer layers of the egg during fertilization.
