Endocrine I Picture Questions Flashcards
What are the arrows pointing to?
Acidophils of the pars distalis.
What are the arrows pointing to?
Basophils of the pars distalis.
What are the arrows pointing to?
Chromophobes of the pars distalis.
Fill in the blanks.
Left to right: pars nervosa, intermedia, distalis
What is the arrow pointing to?
Remnants of Rathke’s pouch.
What cells are the arrows pointing at?
Folliculostellate cells in the pars distalis.
Fill in the blank.
Herring bodies in the axon terminals of the pars nervosa.
Diagnose the tissue and fill in the blanks.
Pineal gland. Top: interstitial (glial) cells. Bottom: Pinealocytes.
Diagnose the tissue and fill in the blanks.
Pineal gland. Top: Interstitial (glial) cells. Bottom: Pinealocytes
Fill in the blanks.
Left: Posterior pituitary (pars nervosa). Right: Anterior (pars distalis).
What are the arrows pointing to?
Remnants of Rathke’s pouch (pituitary)
What are the arrows pointing to?
Islets of Langerhans
Diagnose the tissue and name the thing at the tip of the arrow.
Pineal gland - brain sand (corpora arenacea)
The cells indicated by the arrows:
a) are acidiphiles
b) contain oxytocin
c) reside in the pars distalis
d) contain MSH
e) are lactotrophs
C - Reside in the pars distalis
In the image, the region labeled “1” is derived from?
a) neuroectoderm
b) gut endoderm
c) mesoderm
d) neural crest
e) oral ectoderm
E - Oral ectoderm
In this CT image, the region indicated by the arrow:
a) contains corpora arenacea
b) contains melanin
c) contains Herring bodies
d) contains pituicytes
e) contains cysts (remnants of Rathke’s pouch)
A - Contains corpora arenacea
Which of the following does NOT describe the majority of the cells in this image:
a) they produce MSH
b) are active during darkness
c) the hormones made are derived from serotonin
d) they are pinealocytes
e) they participate in circadian rhythms
A - They produce MSH
They actually produce melatonin. Pars intermedia (pituitary) cells produce MSH.
Which of the following can NOT be said of the structure indicated?
a) it contain fenestrated
capillaries
b) secretes glucagon
c) secretes somatostatin
d) regulated by blood glucose levels
e) secretes steroid hormones
E - Secretes steroid hormones
The regions indicated by the arrows:
a) are islets of Langerhans
b) are derived from the oral cavity
c) are Herring bodies
d) are corpora arenacea
e) are lactotrophs
B - Derived from oral cavity
What is your diagnosis of the cell at *?
a. Basophil
b. Herring body
c. Un-myelinated axon
d. Pituicyte
B - Herring body of the pars nervosa
Which of the following can NOT be said of the cells in this image?
a. Secrete into fenestrated capillaries
b. Produces anti-inflammatory hormones
c. Hormones stored in granules
d. Controlled by ACTH
C - Hormones stored in granules
The picture is of a zona fasciculata (adrenal cortex) rotated 90 degrees. These cells make glucocorticoids like cortisol. The hormones made are not stored, they are released. The storage lipid droplets are cholesterol esters.
This cell can be described by which of the following?
a. Controlled by angiotensin II
b. Involved in glucose metabolism
c. Stimulated by acetylcholine
d. Secretes DHEA
D - Secretes DHEA
It is a cell from the zona reticularis. Note the smooth ER and mitochondria.
Which of the following does NOT apply to this tissue?
a. Increases osteoclast activity
b. Cells are axon-less neurons
c. Secretes a polypeptide hormone
d. Responds to low serum calcium
B - Cells are axon-less neurons
These are parathyroid gland cells. Chief cells make PTH, a peptide hormone to increase osteoclast activity and increase calcium levels.
Chromaffin cells of the adrenal medulla are referred to as axon-less neurons - they secrete epi and norepi.
What disease is this diagnostic of?
Iodine deficiency goiter.
