    Incorrect

    • All of the following organs are involved in oestrogen production except:

      Your Answer: Testes

      Correct Answer: Anterior pituitary

      Explanation:

      Oestrogen can be produced by variety of organs including the corpus leuteum, placenta, adrenal glands and testes. However it is not produced by the anterior pituitary. The anterior pituitary produces LH and FSH which in turn causes oestrogen secretion.

    Correct

    • The following hormones are secreted from the anterior pituitary gland, EXCEPT:

      Your Answer: HCG

      Explanation:

      The following hormones are excreted from the anterior pituitary gland: TSH, GN, ACTH, LH, FSH, MSH, PRL.
      Human chorionic gonadotropin (hCG, or human chorionic gonadotrophin) is a placental hormone secreted by syncitiotrophoblasts during the second week of gestation.

    Correct

    • The source of progesterone that maintains the pregnancy during early 1st trimester:

      Your Answer: Corpus luteum

      Explanation:

      In early pregnancy Progesterone is produced by the corpus luteum.. This organ is fundamental for pregnancy maintenance until the placenta (syncytiotrophoblast) takes over its function at the 7-9th week of gestation, just after the expression of major histocompatibility complex antigens is suppressed in extra-embryonic fetal tissue.

    • In girls what is the first sign of puberty?

      Your Answer: Breast development

      Explanation:

      The first sign of puberty in females is the development of breasts.

    Incorrect

    • Adult Polycystic Kidney Disease (PKD) typically follows which pattern of inheritance

      Your Answer: Polygenic

      Correct Answer: Autosomal Dominant

      Explanation:

      Polycystic kidney disease (PKD) can either be autosomal dominant or recessive. The autosomal dominant variant is more common in adult PKD however, the recessive pattern is more common in infantile PKD.

    Correct

    • Gonadotropin-releasing hormone (GnRH) stimulates the release of:

      Your Answer: Luteinizing hormone

      Explanation:

      Gonadotropin-releasing hormone (GnRH) is the hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland.

  • Question 7 - Which of the following changes would you expect in pregnancy? ...

    Incorrect

    • Which of the following changes would you expect in pregnancy?

      Your Answer: No change TSH Increased Total T3 and T4

      Correct Answer: Decreased TSH Increased Total T3 and T4

      Explanation:

      Human chorionic gonadotrophin (hCG) has thyrotrophic activity owing to subunit homology with thyroid-stimulating hormone (TSH) and maternal TSH production is suppressed during the first trimester of pregnancy, when hCG levels are highest. The TSH response to thyrotrophin-releasing hormone (TRH) is reduced during the first trimester but returns to normal after this. Thyroid binding globulin increases in the first 2 weeks of pregnancy and reaches a plateau by 20 weeks. This leads to increased production of total T3 (tri-iodothyronine) and T4 (thyroxine).

    Correct

    • High levels of alpha feto protein are found in all, EXCEPT?

      Your Answer: Trisomy 21

      Explanation:

      Pregnant maternal serum AFP levels elevated: Neural tube defects (e.g., spina bifida, anencephaly); Omphalocele; Gastroschisis.

      Pregnant maternal serum AFP low levels: Down syndrome

    Incorrect

    • Where are ADH (vasopressin) and Oxytocin synthesised?

      Your Answer: Posterior Pituitary

      Correct Answer: Hypothalamus

      Explanation:

      ADH and vasopressin are synthesized in the supraoptic and periventricular nuclei of the hypothalamus, they are eventually transported to the posterior pituitary where they are stored to be released later.

  • Question 10 - Which of the following hormones are required for alveolar morphogenesis during pregnancy? ...

    Correct

    • Which of the following hormones are required for alveolar morphogenesis during pregnancy?

      Your Answer: Progesterone, Prolactin and hPL

      Explanation:

      The changes seen in breast tissue with the menstrual cycle are accentuated during pregnancy. Deposition of fat around glandular tissue occurs, and the number of glandular ducts is increased by oestrogen, while progesterone and human placental lactogen (hPL) increase the number of gland alveoli. Prolactin is essential for the stimulation of milk secretion and during pregnancy prepares the alveoli for milk production. Although prolactin concentration increases throughout pregnancy, it does not then result in lactation since it is antagonized at an alveolar receptor level by oestrogen.
