Endocrine Histology

Question 1

Answer 1

Adrenal gland

Left most side you can see the capsule

Then you can see glomerulosa- Part of kidney. Quite rounded

Zona fasiculata- look like fascicles

Then criss cross cells- zona reticularis

Question 2

Answer 2

Anterior pituitary

Yellow things on the left- RBCs

Question 3

Answer 3

Parathyroid hormone

Sometimes see cells clumped up with you don’t see in the anterior pituitary

Chief cell- Bluey puink

Blood vessles

Oxyphil cells- Pinker cells

Question 4

Answer 4

Glial cells

Capillaries

Posterior pituitary

Very uncharacteristic of an endocrine- That’s because they just release into blood stream

Oxyphils and adh secreted

Question 5

Answer 5

Question 6

Answer 6

Parathyroid gland

Chief cells and oxyphils which are pinker and the capillaries

Thyroid on the outside whiter area

Question 7

Answer 7

Anterior pituitary gland

Can see pink cells- acidophils

Darker staining- Basophils

Niot stain so well- Chromophones

Bigger red bits are capillaries

Question 8

Answer 8

Thyroid

Cells can be cuboidal or more columnar

Once it produces T3 or T4 it becomes more elongated again

C cells/parafollicular- Secretes calcitonin

Question 9

Answer 9

Pancreas

Islet of Langerhans- around that can see the acinar cells (pancreatic exocrine- serous secretory)

3 different islets int this image

Question 10

Answer 10

This is not an endocrine glands- these are neatly arranged

Acini cells- dark cells

Adipose- clear

Can even see secretory granules- parotid gland

Question 11

Answer 11

Anterior pituitary- Mass of cells with capillaries

Some of them are random but some of them are clumped together

Therefore anterior pituitary

Question 12

Answer 12

Adrenal cortex- Zoomed in

At the top is the capsule

Zona glomerulosa

Then zona fasiculata

Then at the bottom the zona reticularis
