  • Question 1
    1 / -0
    Sertoli cells occur in
    Solution
    Sertoli cells occur in the germinal epithelium of seminiferous tubules. Sertoli cells are also known as nurse cells. They provide nutrition to germ cells called spermatozoa. Spermatozoa are developing sperms. Heads of spermatozoa are embedded in the sertoli cells. Sertoli cells also secrete called inhibin which suppresses FSH synthesis.
  • Question 2
    1 / -0
    Connective tissue around seminiferous tubules possess endocrine cells called?
    Solution
    Connective tissue around seminiferous tubules possesses endocrine cells called Leydig cells. The region outside the seminiferous tubules in testes is called interstitial spaces. It contains small blood vessels and interstitial cells. These interstitial cells are called Leydig cells. Leydig cells constitute the endocrine tissue of the testes. It synthesizes and secretes testicular hormones called androgens. Androgens are a group of male sex hormones, mainly testosterone.
    Thus, the correct answer is option A. 
  • Question 3
    1 / -0
    Cell division that occurs in zygote is known as
    Solution
    When the blastocyst becomes embedded in the endometrium of the uterus, it us known as implantation. 
    Gastrulation is a process in which single layered blastula rearrange itself into multilayered gastrula.
    When zygote undergoes mitotic division it is known as cleavage.
    When a cell differentiates i.e. changes from one type to another, it is known as differentiation.
    So, the correct option is 'Cleavage'.
  • Question 4
    1 / -0
    Accessory genital gland found only in male is
    Solution
    Cowper's gland or Bulbourethral gland is found in males responsible for lubrication of penis. It is homologous to Bartholine gland found in females. The perineal gland is found near the anus responsible for odorous substance. The prostate gland is found in males which makes the semen alkaline in nature to neutralize the acidity of the vagina.
    So, the correct option is 'Prostate gland'.
  • Question 5
    1 / -0
    Which among the following describe the sperm production in adult males?
    Solution
    Testes are the primary sex organs in males. They have tightly packed tubules involved in the production of sperms and testosterone that are called seminiferous tubules. Seminiferous tubules start producing sperms when a male reaches puberty and continue to do so their entire life. The sperm formation does not depend on some particular occasion or time period instead, sperm-production happens continuously.
    So, the correct answer is 'Continuously'.
  • Question 6
    1 / -0
    Sertoli cells are found in?
    Solution
    The seminiferous tubule is lined on its side by two types of cells called male germ cells which undergo meiotic divisions finally leading to sperm formation and sertoli cells provide nutrition to germ cells.
    So the correct answer is option C. 
  • Question 7
    1 / -0
    Identify Cowper's gland from the following figure. 

    Solution
    In the figure 
    $$D =$$ Epididymis 
    $$C =$$ Cowpers gland 
    $$B =$$ Prostate gland 
    $$A =$$ Seminal vesicle 
  • Question 8
    1 / -0
    The capsule enclosing testis of mammal is called as
    Solution
    Tunica albuginea is the fibrous envelope of the testes.
    Tunica media lies between the tunica intima on the inside and the tunica externa on the outside.
    Tunica vasculosa is the vascular layer of the testis.
    Tunica vaginalis is a mesothelium-lined sac.
    Thus, the correct answer is option A.
  • Question 9
    1 / -0
    The duct which conveys sperm from the testis to the ejaculatory duct, is
    Solution
    The correct answer is vas deferens
    • The vas deferens is a muscular tube in the male reproductive system that carries sperm from the epididymis to the ejaculatory duct. seven up is a nemonic used to remember the ejaculation pathway of sperm. This represents the Seminiferous tubules, Epididymis, Vas deferens, Ejaculatory ducts, nothing, Urethra and Penis.

    • Ureter is a tube that carries urine from the kidney to the urinary bladder
    • Ductus dodo lymphaticus is a lymphatic duct.
    • primordial analog of the female reproductive tract. They differentiate to form the fallopian tubes, uterus, the uterine cervix, and some aspects of the vagina.
  • Question 10
    1 / -0
    Which of the following is an accessory reproductive gland in male mammals? 
    Solution
    The prostate gland is a single exocrine gland located between the bladder and penis in male mammals, which produces a large portion of the fluid, which makes up the semen when mixed with sperm. Whereas the gastric glands or fundic glands are found in the body, the gastric mucosa and fundus of the stomach (in all mammals), the mushroom shaped gland is not present in males and the inguinal canal is the passage in the abdominal wall present in both men and women.
    Thus, the correct answer is option A.
