Test: The Male Reproductive System (November 1) - Question 1

What is the primary function of the testes in the male reproductive system?

Detailed Solution for Test: The Male Reproductive System (November 1) - Question 1
The primary function of the testes in the male reproductive system is to produce testosterone, which is a male sex hormone, and to produce sperm through a process called spermatogenesis. Testosterone plays a crucial role in the development of male secondary sexual characteristics, such as facial hair and deepening of the voice, while spermatogenesis involves the production of sperm, which are the male gametes responsible for fertilization.
Test: The Male Reproductive System (November 1) - Question 2

Which male accessory gland is responsible for generating fluid rich in fructose, calcium, and enzymes that nourishes sperm?

Detailed Solution for Test: The Male Reproductive System (November 1) - Question 2
The seminal vesicles are responsible for generating fluid rich in fructose, calcium, and certain enzymes. This fluid, known as seminal plasma, nourishes the sperm and constitutes the majority of the volume of semen. It provides important nutrients to support sperm function.

Test: The Male Reproductive System (November 1) - Question 3

What is the function of the urethra in males?

Detailed Solution for Test: The Male Reproductive System (November 1) - Question 3
The urethra in males serves the function of transporting urine from the bladder and, in addition, it is the channel through which semen is ejaculated during ejaculation. It is part of both the urinary and reproductive systems.
Test: The Male Reproductive System (November 1) - Question 4
What is the function of Leydig cells in the male reproductive system?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 4
Leydig cells, also known as interstitial cells, are responsible for producing male sex hormones, specifically androgens like testosterone. These hormones play a key role in regulating various aspects of male reproductive development and function.
Test: The Male Reproductive System (November 1) - Question 5
Which part of the male reproductive system becomes rigid when filled with blood during sexual arousal?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 5
The penis becomes rigid when its erectile tissue, consisting of the corpora cavernosa and corpus spongiosum, is filled with blood during sexual arousal. This rigidity facilitates sexual intercourse and insemination.
Test: The Male Reproductive System (November 1) - Question 6
Which part of the male reproductive system is responsible for temperature regulation of the testes?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 6
The scrotum is responsible for temperature regulation of the testes. It houses the testes in a pouch of skin and muscle, allowing them to hang slightly away from the body. This positioning helps maintain a temperature slightly lower than the body's core temperature, which is essential for proper sperm production.
Test: The Male Reproductive System (November 1) - Question 7
Where does spermatogenesis, the production of sperm, primarily occur in the male reproductive system?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 7
Spermatogenesis primarily occurs in the seminiferous tubules of the testes. These tubules are lined with two types of cells: spermatogonia (male germ cells), which undergo spermatogenesis to produce sperm, and Sertoli cells, which provide nutrition to the germ cells.
Test: The Male Reproductive System (November 1) - Question 8
What is the function of the male accessory glands in the male reproductive system?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 8
The male accessory glands, including the seminal vesicles, prostate, and bulbourethral glands, generate fluid that nourishes sperm. This fluid, known as seminal plasma, contains nutrients like fructose, calcium, and enzymes and constitutes a significant portion of semen.
Test: The Male Reproductive System (November 1) - Question 9
Which part of the male reproductive system covers and surrounds the testes, helping to regulate their temperature?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 9
The scrotum covers and surrounds the testes in a sac of thick skin and muscle. It plays a vital role in regulating the temperature of the testes, ensuring they are slightly cooler than the body's core temperature for optimal sperm production.
Test: The Male Reproductive System (November 1) - Question 10
What is the primary function of the prostate gland in the male reproductive system?
Detailed Solution for Test: The Male Reproductive System (November 1) - Question 10
The primary function of the prostate gland in the male reproductive system is to generate fluid that nourishes sperm. The prostatic fluid, when combined with seminal plasma from the seminal vesicles and other secretions, forms semen, which carries and nourishes sperm during ejaculation.
