TOPIC # 11 DEVELOPMENT OF ENDOCRINE SYSTEM

Question 1

The is composed of the pituitary, pineal, thyroid, parathyroid and adrenal
glands.

Answer 1

endocrine system

Question 2

The consists of adenohypophysis derived from stomodeal ectoderm and
neurohypophysis derived from neural ectoderm.

Answer 2

pituitary gland

Question 3

The is connected to the hypothalamus the infundibular stalk

Answer 3

neurohypophysis

Question 4

is derived from endoderm lining the floor of the pharynx between pharyngeal pouch 1
and 2.

Answer 4

thyroid

Question 5

The gland is classified as

Answer 5

external parathyroid and internal parathyroid

Question 6

The is adjacent to the cranial pole of the kidney.

Answer 6

adrenal gland

Question 7

gland consists of

Answer 7

peripheral cortex and a central medulla.

Question 8

is derived from intermediate mesoderm mesenchymal cells (cells
of mesonephric nephrons that dissociate from the nephron when mesonephros
degenerates and migrate to the future location of the adrenal) around the adrenal
medulla that proliferate, push toward the medulla and form cords.

Answer 8

fetal adrenal cortex

Question 9

is formed by neural crest cells that have migrated into the adrenal
cortex beneath the intermediate mesoderm

Answer 9

adrenal medulla

Question 10

The is derived from the ectoderm lining the root of the diencephalon (neural
ectoderm) that evaginates to form the epiphysis cerebri.

Answer 10

penial gland
