Reproduction - Part 3

What is the most relevant definition of puberty?

• It is the age at which primary sex organs starts to develop in foetus

• It is the age at which, male starts to develop sperms in testes and female starts to develop follicles in ovaries

• It is the age at which, testes starts to produce testosterone in males and ovaries starts to produce progesterone in females

• It is the age at which all the organs are fully developed in foetus

Which substance control puberty in humans?

• Proteins

• Hormones

• Carbohydrates

• Vitamins

Which statement is not correct?

• Testosterone stimulate growth of facial hairs in males

• Oestrogen stimulates the growth and development of breasts

• Oestrogen stimulates the start of first menstrual cycle and the first period

• Testosterone stimulates the widening of hips

What is the average time period of normal menstrual cycle in females?

• 25 days

• 30 days

• 20 days

• 28 days

What happens during the menstrual cycle?

• A follicle matures and release the ovum in one of the ovary called as ovulation

• The oocyte released by the ovary, if not fertilised, comes out of vagina as dead cell along with the shading of uterine wall and blood

• The wall of uterus, called as endometrium fully develops and ready for the implantation

• All of the above

Which statement is correct?

• The development of sperms in testes starts at the age of puberty in males

• The development of follicles in the ovaries starts during the embryonic stage in females

• When female child takes birth, she already have thousands of undeveloped follicles in each ovary

• All of above

What is the most relevant definition of implantation?

• It is the stage at which, fertilized egg divides into ball of cells and sinks in the endometrium wall of uterus

• It is the stage at which fertilized egg moves down the fallopian tube and converts into the ball of cells

• It is the stage at which egg enters in the fallopian tube and ready to be fertilized with the sperm cell

• It is the stage at which a mature follicle ruptures and releases the egg cell

Stages in the menstrual cycle includes:

1. Ovulation releases egg cell from one of the ovary

2. Wall of uterus sheds away

3. No fertilization takes place

4. Dead egg cell along with uterine wall and blood comes out of vagina

What is the correct order of the stages given?

• 1 --> 2 --> 4 --> 3

• 1 --> 3 --> 2 --> 4

• 2 --> 3 --> 1 --> 4

• 2 --> 1 --> 3 --> 4

After ovulation, the left out mass of follicle develops a yellow body. What is the biological term for this yellow body?

• Endometrium

• Pineal body

• Corpus luteum

• Granulosa cell mass

What is the correct match?

• Ovaries secretes the Follicle stimulating hormone (FSH)

• Pituitary gland secretes the hormone progesterone

• Pituitary gland secretes the Luteinising hormone (LH)

• Ovaries secretes the Luteinising hormone (LH)
