Flashcards in Block 4 - Thyroid Gland Deck (21):
1

secretory cells in thyroid gland are organized into blank

follicles

2

synthesis of hormone in thyroid is initiated blank the cell and completed blank the cell

inside, outside

3

secretion of thyroid is stored in follicles blank the cell as a blank rather than in blank

outside, prohormone, secretion granules

4

parathyroid is formed from these gill arches

3,4

5

two very distinguishable parts of parathyroid

oxyphil cell, lipids

6

oxyphil cells have a blank function

unknown

7

parathyroid also has blank cells that respond to decreased calcium in the blood

chief

8

follicle cells look like this in 3 dimensions

golf balls

9

clear cell in thyroid that makes calcitonin (C cell)

parafollicular cells

10

calcitonin is released when blood calcium is blank

high

11

thyroid blank calcium while parathyroid blanks calcium

decreases, increases

12

parafollicular cells are in thyroid or parathyroid?

thyroid

13

things between follicles

collagen, blood vessels, lymphatics

14

colloid is made up of blank

prohormone

15

more colloid looks more blank

basophilic

16

areas of terminal bar

zonula occludens (tight junction), zonula adherens, macula adherens (desmosome)

17

terminal bar prevents blank of colloid and blank the cells

leakage, holds together

18

phagosome retrieves prohormone from the blank and brings it to blank

colloid, inside of the cell

19

phagosome releases blank and blank

T3, T4

20

phagosome doesnt release these and brings them back in

T1, T2

21

thyroid is a blank organ

endocrine
