|| Correct! Diethylstilbetrol (DES) mimics acts as a potent {{estrogen}} (mimics the natural hormone) and therefore a potential endocrine disruptor. DES was a drug prescribed to women from 1938-1971 to prevent miscarriage in high-risk pregnancies. In a female fetus, increased risk abnormal reproductive tract (vaginal abnormalities) and cancer. In a male fetus, abnormal genitalia.

Endocrine Development Interactive Component

Attempt the Quiz - Endocrine Development  
BGDsmall.jpg

Here are a few simple Quiz questions that relate to Endocrine development and abnormalities from the lecture. Some questions may require some additional research.


Syntax error

1

Which of the following originates from surface ectoderm?

  neurohypophysis
  adenohypophysis
  adrenal cortex
  thyroid
  parathyroid

2

Which of the following arise from the endoderm?

  the pancreatic acinous cells
  B-cells
  a-cells
  pancreatic duct cells
  all of the above

3

The neural crest cells from the sympathetic ganglia migrate to form the:

  pars nervosa of the pituitary gland
  medulla of the adrenal gland
  follicular cells of the thyroid gland
  inferior parathyroids
  pars intermedia of the pituitary gland

4

During fetal life the parathyroid glands:

  contain oxyphil cells that degenerate before birth
  contain parafollicular cells that secrete hormones to regulate
  develop in situ from cervical somites
  migrate cephalically from the thymus to reach the cervical region

5

The parafollicular cells of the thyroid originate from the:

  ectoderm
  mesoderm
  endoderm
  neuroepithelium
  neural crest

6

Congenital suprarenal hyperplasia:

  causes an increase in adrenal cortical hormones
  inhibits release of ACTH by the pituitary
  causes masculinisation of external genitalia in female fetuses
  may lead to adrenal cortical insufficiency, although there is an
  overproduction of adrenal cortical hormones

7

Pituitary hypoplasia may result in:

  achondroplasia
  maldevelopment of the adrenal cortex
  maldevelopment of the thyroid gland
  hypoplastic gonads
  all of the above

8

In congenital adrenal hypoplasia due to unresponsiveness to ACTH:

  the aldosterone levels are normal
  the skin is hyperpigmented
  the ACTH level is increased
  all of the above are correct

9

Which of the following is the most correct statement concerning the thyroid pyramidal lobe:

  is a failure of thyroid descent
  is a persistance of thyroglossal duct
  occurs in about 1 in 3000 births
  is associated with neurological abnormalities
  occurs in about 50% of people

10

Endocrine disruptors are exogenous chemicals that interfere with the function of hormones. Which of the following best describes the endocrine action of "Diethylstilbestrol (DES)"?

  Mimics to replicate the effects of natural hormones by binding receptors
  Blocks to inhibit the binding of a hormone to receptor or hormone synthesis
  Interferes to compromise with the hormone transport or elimination
