Question-1

Ovulation in the human female normally takes place during the menstrual cycle

(a)

(b)

(c)

(d)

Explanation:

Answer: (d)

Ovulation (the release of secondary oocyte from the graafian follicle) takes place at the end of proliferative phase of menstrual cycle. During this phase, the follicle stimulating hormone (FSH) secreted by the anterior lobe of the pituitary gland stimulates the ovarian follicle to secrete estrogen. Estrogen stimulates the proliferation of the endometrium of the uterine wall. The endometrium becomes thicker by rapid cell multiplication and this is accompanied by an increase of uterine glands and blood vessels. This phase ends when the ovarian follicle ruptures and ovulation occurs and at the same time the production of estrogen stops.

(a)

(b)

(c)

(d)

Explanation:

Answer: (b)

The structures marked in the figure of mammary gland are A–mammary lobe, B–mammary duct, C–ampulla, and D–lactiferous duct. The mammary gland is a gland located in the breasts of females that is responsible for lactation. Mammary glands only produce milk after childbirth. Mammary lobe (A) contains clusters of cells called alveoli which secrete milk which is stored in the cavities of alveoli.


Question-4

The sperm head contains:

(a)

(b)

(c)

(d)


Question-5

Read the following statements (i to iv) and answer the following question.
  1. Each testes has highly coiled 250 compartments called seminiferous tubules.
  2. Erection of the penis due to presence of special tissues facilitates insemination.
  3. Immunologically competent cells are also present in the interstitial spaces of seminiferous tubules.
  4. Testes lie outside the abdominal cavity in a thin pouch like skin called scrotum.
  5. Bulbourethral gland is a single accessory gland.
How many of the above statements are incorrect?

(a)

(b)

(c)

(d)

Explanation:

Answer: (c)

Each testes has about 250 compartments called testicular lobules.Each lobule contains one to three highly coiled seminiferous tubules. Bulbourethral glands are paired male accessory glands.
