Attempt the Quiz - Endocrine Development

Here are a few simple Quiz questions that relate to Endocrine development and abnormalities from the lecture. Some questions may require some additional research. 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 Additional Information: endocrine | BGD Lecture | Science Lecture | Lecture Movie | pineal | hypothalamus‎ | pituitary | thyroid | parathyroid | thymus | pancreas | adrenal | endocrine gonad‎ | endocrine placenta | other tissues | Stage 22 | endocrine abnormalities | Hormones | Category:Endocrine
