55
Identify the region defined by the square (high magnification of area in right panel)
zona glomerulosa
56
what is the hormone product of the cells?
mineralocorticoids
57
Identify the region defined by the square (high magnification to right).
zona fasciculata
58
In the above image what hormone do the cells produce?
glucocorticoids
59
what is the region immediately deep to the boxed in area (but still within the cortex)?
The cells in this area secrete glucocorticoids and also sex hormones (e.g., estrogens and androgens) in response to ACTH. Usually in the Cushing's syndrome (hyperadrenocorticism) you anticipate the production of excess glucocortcoids - but imagine what clinical signs you might see with the concurrent excess production of the sex hormones??
The correct answer is: zona reticularis
60
what are the two hormones produced by the medullary cells (please separate your answers with a comma).
epinephrine, norepinephrine
61
The cells of this medullary region are really modified post-ganglionic ________ neurons.
Recall that this region is derived from neuroectoderm so it makes sense that the cells are neurons. This also means that the cells are directly innervated by a preganglionic axon and as part of the sympathetic nervous system you would expect stimulation of the cells during "fight or flight" type situations.
The correct answer is: sympathetic
62
The cell indicated by the blue arrow belongs to the "diffuse neuroendocrine system" - a group of cells scattered throughout the body which produce hormones. Please (accurately) write out the entire name of these cells.
The name of these cells actually describes their function i.e., they uptake amines and then decarboxylate them to produce the active hormone.
The correct answer is: amine precursor uptake and decarboxylation cells
63
Identify the cell labelded "A" (Please write the name of the organ then the cell type i.e., Answer _______ cell).
thyroid follicular cell
64
Name one of the active forms of the hormone produced by the thyroid follicular cell (you can write the answer as a single letter number combination or you can write the full name out).
T3
65
In the above image identify cell "B". Again, please write the name of the organ as the first part of the answer i.e., Answer ______ cell
thyroid parafollicular cell
66
What is the hormone produced by the thyroid parafollicular cells?
Calcitonin
67
Indicate how Calcitonin alters the blood calcium level. Please write your answer as one of the following choices: increases / decreases
Note that parathyroid hormone alters blood calcium in the opposite direction to this hormone.
The correct answer is: decreases
