WorksheetsThyroid, Parathyroid and Thymus Glands Review
Total questions: 22
Worksheet time: 19mins
Thymosins are paracrine hormones secreted by the (a) gland.
Thymosins:
regulated the metabolism by affecting the mitochondria
lower blood calcium
raise blood calcium
aid in development of immune cells
turn off the thyroid gland secretion
The most abundant cell of the thyroid gland is called the:
parafollicular cell
follicular cell
colloid cell
C cell
Identify the substance at the arrows in the image.
(a)
What is the function of the colloid?
a storage area for iodine
a storage site for T3 and T4
a storage site for calcitonin
a storage site for TSH
What element is necessary for the T3 and T4 to be produced properly?
(a)
Which thyroid cells are shown here?
C cells
parafollicular cells
follicular cells
colloid cells
(Select all that apply.)
Which thyroid cells are shown here at the red circles?
C cells
parafollicular cells
follicular cells
colloid cells
Which hormone(s) are produced by the cells shown here? (Select all that apply)
calcitonin
T3
T4
TSH
What hormone(s) are produced by the cells shown here at the red circles?
calcitonin
T3
T4
TSH
parathormone
What hormone(s) are produced by the cells shown here at the red circles? (select all that may apply)
calcitonin
T3
T4
TSH
Thyroid hormones are:
steroid based
amino acid based
Select all correct statements.
Calcitonin....
is released when blood calcium is high
is triggered by a humoral stimulus
is produced by follicular cells
increases calcium absorption by intestines into blood
is the functional OPPOSITE of parathormone
Which of the following are a thyroid hormone related disorders? Select all that apply.
Hashimoto's
gigantism
Graves'
Diabetes insipidus
goiter
Iodine deficiency causes:
Hashimoto's
gigantism
Graves'
Diabetes insipidus
goiter
Which of the following are actions of thyroid hormones? Select all that apply.
elevates blood calcium levels
increases ATP production in mitochondria
lowers blood calcium levels
secretes hormones to control the adrenal cortex
increases rate of cellular metabolism
Identify the small portion of the thyroid connecting the right and left lateral lobes.
(a)
The hormone produced by the parathyroid gland is called:
(a)
When blood calcium is high, the (a) is/are stimulated to secrete the hormone called (b) .
When blood calcium is low, the (a) is/are stimulated to secrete the hormone called (b) .
Match the following hormones to their actions.
parathormone
raises blood calcium
calcitonin
lowers blood calcium
tetraiodothyronine & triiodothyronine
elevates ATP production in mitochondria
thymosins
helps immune cells develop
ACTH
turns on the adrenal cortex
Parathormone:
is released during hypocalcemia
speeds up one's metabolism
elevates blood calcium levels
lowers blood calcium levels
is released during hypercalcemia
