- &nbsp; neurohypophysis
- &nbsp; neurohypophysis
|| Incorrect! The {{neurohypophysis}} ({{posterior pituitary}}) originates from neural ectoderm.
+ &nbsp; adenohypophysis
+ &nbsp; adenohypophysis
|| Correct? The adenohypophysis (anterior pituitary) originates from a midline surface ectoderm placode lying outside the buccopharyngeal membrane
|| Correct! The {{adenohypophysis}} ({{anterior pituitary}}) originates from a midline surface ectoderm {{placode}} lying outside the buccopharyngeal membrane.

- &nbsp; thyroid
|| Incorrect!
- &nbsp; parathyroid
- &nbsp; parathyroid
|| Incorrect!
{Which of the following arise from the endoderm?
|type="()"}
- &nbsp; the pancreatic acinous cells
|| Correct! But not the correct answer option to this question. All of the endocrine and exocrine structures of the {{pancreas}} are derived from endoderm.

|| Correct! But not the correct answer option to this question. All of the endocrine and exocrine structures of the {{pancreas}} are derived from endoderm.
+ &nbsp; all of the above
|| Correct? All of the above endocrine and exocrine structures of the {{pancreas}} are derived from endoderm.
{The neural crest cells from the sympathetic ganglia migrate to form the:

- &nbsp; pars nervosa of the pituitary gland
+ &nbsp; medulla of the adrenal gland
|| Correct! Neural crest cells from the sympathetic ganglia migrate to form the adrenal medulla.
- &nbsp; follicular cells of the thyroid gland
- &nbsp; inferior parathyroids
- &nbsp; pars intermedia of the pituitary gland
{During fetal life the parathyroid glands:
|type="()"}
- &nbsp; contain oxyphil cells that degenerate before birth
|| Incorrect!
+ &nbsp; contain parafollicular cells that secrete hormones to regulate
fetal calcium metabolism
|| Correct! During fetal life the parathyroid glands secrete hormones to regulate
fetal calcium metabolism.
- &nbsp; develop in situ from cervical somites
|| Incorrect!
- &nbsp; migrate cephalically from the thymus to reach the cervical region
|| Incorrect!
{The parafollicular cells of the thyroid originate from the:

- &nbsp; mesoderm
|| Incorrect!
+ &nbsp; endoderm
|| Correct! The parafollicular cells of the thyroid originate from pharynx endoderm.
- &nbsp; neuroepithelium
|| Incorrect!
- &nbsp; neural crest
|| Incorrect!
{Congenital suprarenal hyperplasia:
|type="()"}
- &nbsp; causes an increase in adrenal cortical hormones
|| Incorrect!
- &nbsp; inhibits release of ACTH by the pituitary
|| Incorrect!
+ &nbsp; causes masculinisation of external genitalia in female fetuses
|| Correct!
- &nbsp; may lead to adrenal cortical insufficiency, although there is an

- &nbsp; hypoplastic gonads
|| Correct! But not the correct answer option to this question.
+ &nbsp; all of the above
|| Correct! And the correct answer option to this question. Pituitary hypoplasia (under or incomplete development) and the associated decrease in the endocrine effects can lead to "downstream" endocrine organ abnormalities.
{In congenital adrenal hypoplasia due to unresponsiveness to ACTH:
|type="()"}
cthe electrolyte levels are normal
|| Correct! But not the correct answer option to this question.
- &nbsp; the aldosterone levels are normal
|| Correct! But not the correct answer option to this question.
- &nbsp; the skin is hyperpigmented
|| Correct! But not the correct answer option to this question.
- &nbsp; the ACTH level is increased
|| Correct! But not the correct answer option to this question.
+ &nbsp; all of the above are correct
|| Correct! And the correct answer option to this question.
{Which of the following is the most correct statement concerning the '''thyroid pyramidal lobe''':
|type="()"}
- &nbsp; is a failure of thyroid descent
|| Incorrect! This is lingual thyroid gland
- &nbsp; is a persistance of thyroglossal duct
|| Incorrect! this is a thyroglossal cyst
- &nbsp; occurs in about 1 in 3000 births
|| Incorrect! This is the congenital hypothyroidism rate
- &nbsp; is associated with neurological abnormalities
|| Incorrect! This is the congenital hypothyroidism
+ &nbsp; occurs in about 50% of people
|| Correct!
{Endocrine disruptors are exogenous chemicals that interfere with the function of hormones. Which of the following best describes the endocrine action of "Diethylstilbestrol (DES)"?
|type="()"}
+ &nbsp; Mimics to replicate the effects of natural hormones by binding receptors
|| 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.
- &nbsp; Blocks to inhibit the binding of a hormone to receptor or hormone synthesis
|| Incorrect!
- &nbsp; Interferes to compromise with the hormone transport or elimination
|| Incorrect!
