Sample questions

  1. 1.Why is it that most often only one embryo is formed at a time in women, despite the presence of two ovaries?
    • A.Only one ovary is functional at any given time.
    • B.Normally, only one egg matures in each ovary every alternate month.
    • C.The uterus can only support one embryo at a time.
    • D.Fertilization usually occurs in only one fallopian tube.
  2. 2.What best describes the concept of a positive feedback mechanism with reference to uterine contractions during childbirth?
    • A.Each uterine contraction inhibits further contractions, maintaining a stable state until childbirth.
    • B.Uterine contractions stimulate further contractions, intensifying until childbirth is complete.
    • C.Uterine contractions occur randomly and independently of each other during childbirth.
    • D.Contractions weaken over time due to fatigue, requiring medical intervention to complete childbirth.
  3. 3.In female after how much time after fertilisation does the fertilised egg get implanted in the uterine wall?
    • a.few months
    • b.one month
    • c.about seven days
    • d.three weeks
  4. 4.Which of the following correctly identifies an accessory gland in the male reproductive system and describes the function of its secretion?
    • A.Prostate gland; its secretion forms part of the semen and provides nourishment to the sperm.
    • B.Seminal vesicle; its secretion produces testosterone to enhance sperm motility.
    • C.Bulbourethral gland; its secretion lubricates the penis but does not affect semen.
    • D.Epididymis; its secretion stores sperm and allows them to mature before ejaculation.
  5. 5.What are the accessory reproductive organs?
    • A.Organs that produce gametes such as testes and ovaries.
    • B.Structures that support gamete production, transport, or nourishment but do not produce gametes themselves, like ducts, glands, and external genitalia.
    • C.Organs responsible solely for hormone production in the reproductive system.
    • D.Parts of the reproductive system that store gametes indefinitely until fertilization.
