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

​If for some reason, the vasa efferentia in the human reproductive system get blocked, the gametes will not be transported from

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 1

Vasa efferentia are fine ciliated ductules that arise from the seminiferous tubules of testis (where sperms are formed) and open into epididymis which is a mass of long narrow closely coiled tubule lying along the inner side of testis. Epididymis stores the sperms. Thus, if vasa efferentia get blocked, sperms will not be transposed from testes to epididymis.

Topic in NCERT: Male Reproductive System

Line in NCERT: "The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis."

Test: The Male Reproductive System (NCERT) - Question 2

The nutritive cells found in seminiferous tubules are

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 2

Wall of each seminiferous tubule is formed of a single layered germinal epithelium. Majority of cells in this epithelium are male germ cells and at centain places, there are persent tall Sertoli cells. These cells act as nurse cells providing nutrition to the developing sperms.

Topic in NCERT: Gametogenesis

Line in NCERT: "Sertoli cells provide nutrition to the germ cells."

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 3

Secretion of seminal vesicle, prostrate gland and bulbourethral gland Constitute seminal plasma which is rich in fructose, calcium and certain enzymes.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Test: The Male Reproductive System (NCERT) - Question 4

In most mammals, the testes are located in scrotal sac for

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 4

In mammals, scrotal sacs (containing testes) act as thermoregulator, maintaining the temperature of the testes 2C lower than that of the body. This temperature is required for the spermatogenesis to occur, otherwise, the sperms could be destroyed by high temperature, resulting in sterility.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The scrotum helps in maintaining the low temperature of the testes (2-2.5°C lower than the normal internal body temperature) necessary for spermatogenesis."

Test: The Male Reproductive System (NCERT) - Question 5

Read the following statements about the given diagram carefully and state which of them are correct?

(i) A carries urine and C stores sperms.
(ii) B secretes a fluid that helps in the lubrication of penis.
(iii) D produces testosterone but not sperms
(iv) C stores sperms

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 5

In the given figure, part 'A' is vs deferens that carries sperms. Part 'B' is Cowper's glands that secreate fluid which helps in the lubrication of the penis during copulation. Part 'C' is epididymis that stores sperms and part 'D' is testis that produces sperms and testosterone.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The secretions of bulbourethral glands also helps in the lubrication of the penis."

Test: The Male Reproductive System (NCERT) - Question 6

Where is the male reproductive system located?

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 6

  • The male reproductive system is located in the pelvis region.
  • It includes a pair of testes along with accessory ducts, glands and the accessory or external genitalia.

Topic in NCERT: THE MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The male reproductive system is located in the pelvis region."

Test: The Male Reproductive System (NCERT) - Question 7

Prostate glands are located below

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 7

The prostate gland (small and walnut-shaped) is located beneath the seminal vesicle and secretes a fluid that nourishes and protects sperm. The prostate is just in front of the rectum. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The male accessory glands (Figure 2.1a, b) include paired seminal vesicles, a prostate and paired bulbourethral glands."

Test: The Male Reproductive System (NCERT) - Question 8

Which one is correct for mammalian testis?

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 8

Graafian follicles are present in human ovaries.

Test: The Male Reproductive System (NCERT) - Question 9

Match each function below with the associated part or parts of the human male reproductive system shown in the figure.
(i) Produces sperm
(ii) Conducts the sperm through the penis to the outside of the body
(iii) Produces seminal fluid
(iv) Connects the epididymis with the urethra

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 9

In the given figure: 
A. Seminal vesicle
B. Vas deferens
C. Prostate gland
D. Bulbourethral gland
E. Urethra
F. Epididymis
G. Seminiferous tubules

Test: The Male Reproductive System (NCERT) - Question 10

The given diagram refers toT.S. of testis showing sectional view of a few seminiferous tubules. Identify the parts labelled A-D and select the correct option.

Biology Question Image

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 10

The testis consists of seminiferous tubules that consist of Sertoli cells that provide nutrition to the germ cells and these cells are lined on the inside along with Spermatogonia or the male germ cells. The regions towards the outside (interstitial spaces) contain interstitial cells. The matured spermatogonia are the spermatozoa or sperms that are present in the interior of the seminiferous tubule.

Topic in NCERT: GAMETOGENESIS

Line in NCERT: "The seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells."

Test: The Male Reproductive System (NCERT) - Question 11
Where does the urethra extend from and what is its external opening called?
Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 11

The urethra originates from the urinary bladder and extends through the penis to its external opening, which is called the urethral meatus.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The urethra originates from the urinary bladder and extends through the penis to its external opening called urethral meatus."

Test: The Male Reproductive System (NCERT) - Question 12
What is the enlarged end of the penis called, and what covers it?
Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 12

The enlarged end of the penis is called the glans penis, and it is covered by a loose fold of skin known as the foreskin. The foreskin is also referred to as the prepuce.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "The enlarged end of penis called the glans penis is covered by a loose fold of skin called foreskin."

Test: The Male Reproductive System (NCERT) - Question 13
Epididymis is located on the….of the testis.
Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 13

The epididymis is located on the posterior surface of the testis, where it plays a key role in the storage and maturation of sperm.

Topic in NCERT: MALE REPRODUCTIVE SYSTEM

Line in NCERT: "the vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis."

Test: The Male Reproductive System (NCERT) - Question 14

(i) Rete testis
(ii) Vasa efferentia
(iii) Vas deferens
(iv) Epididymis

Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 14

The vas deferens and epididymis are ducts located outside the testis:

Vas deferens: A duct that transports sperm from the epididymis to the ejaculatory duct.
Epididymis: A coiled tube that stores and matures sperm.
The rete testis and vasa efferentia are located within the testis. Therefore, the correct answer is Option B.

Test: The Male Reproductive System (NCERT) - Question 15
Which human male accessory reproductive duct receives a duct from the seminal vesicle?
Detailed Solution for Test: The Male Reproductive System (NCERT) - Question 15

The vas deferens is the duct that receives a duct from the seminal vesicle. The vas deferens joins with the duct from the seminal vesicle to form the ejaculatory duct, which then leads to the urethra. This process is essential for the transport of sperm and seminal fluid during ejaculation.

Topic in NCERT: Male Reproductive System

Line in NCERT: "It receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct."
