Flashcards in Lec 3-6 - Thyroid Deck (17):
1

hormone that enables other hormones to work normally

permissive hormone

2

cells in the thyroid that actually make thyroid hormone

follicular cells

3

where thyroid stores thyroid hormone

colloid inside thyroid itself

4

t4 is aka

thyroxine

5

t4 is the blank

prohormone

6

t3 actually blank

does the most activity

7

t3 is aka

triidothyronine

8

enzyme required to put iodine on to thyroglobulin to make t3 and t4

thyroid peroxidase

9

steps in making t3 and t4

iodine comes into follicular cell, thyroid peroxidase puts iodine on thyroglobulin and stores in colloid, long chain goes back into follicular cell and is snipped into t1,t2,t3,t4; we use the t3 and t4 and recycle t1 and t2

10

not enough iodine causes blank

no negative feedback so amount of thyroid stimulating hormone in colloid increases and thyroid gets huge because t3 and t4 doesnt get released from the colloid

11

does t3 or t4 actually do the negative feedback on thyrotrophs

t3

12

transport of thyroid hormone is via

thyroxine binding globulin, albumin (main one)

13

thyroid hormone causes growth of blank by setting the stage for other hormones

skeletal system, teeth, central nervous system

14

thyroid hormone causes increased metabolism by using more blank by breaking down more lipids and proteins

oxygen

15

therefore, hyperthyroidism causes blank which leads to feeling blank all the time and blank heart rate

catabolism, hot, increased

16

hyperthyroidism is aka blank

grave's disease

17

hypothyroidism is aka blank

hashimoto's disease
