Q

What organ is this from?

What does the arrow point to?

Star?

1, 2, 3?

A

Ovary

Arrow: ​Peritoneal Epithelium (simple cuboidal)

Star: Graafian Follicle (although it’s labeled as a Tertiary Follicle, but looks much like a deeper Graafian. Gonna ask about this one)

1: Primary Follicles
2: Primordial Follicles
3: Secondary Follicle (probably)

(lemme know if you think one of these is wrong! if I remember correctly, the Hungarian way to classify these is slightly different than in English books, maybe more similar to German books)

Q

What tissue is this?

A

Vagina

Note:

  • Wide lamina propria mucosae has lots of CT with elastic fibers
  • Vaginal wall has neither glands nor submucosa
  • Esophagus easily distinguished from vagina bc esophagus has muscularis mucosae, tela submucosa, and glands
  • Ureter has transitional epithelial lining and regular smooth muscle in its tunica muscularis

Q

What tissue is this?

What glands are here?

A

Non-Lactating Breast

There are Areolar Glands of Montgomery here: apocrine secretion

Areolar glands or Glands of Montgomery are sebaceous glands in the areola surrounding the nipple. The glands make oily secretions (lipoid fluid) to keep the areola and the nipple lubricated and protected. Volatile compounds in these secretions may also serve as an olfactory stimulus for newborn appetite.

Q

What 2 parts of the pituitary gland do you see here?

A

Intermediate Part to the left

Neurohypophysis takes up the rest of the image

25
Q

What tissue is this?

What important cell types/structures are here?

A

Neurohypophysis

Look for pituicytes: special glial cells, only their oval pale nucleus can be seen

I don’t think the Herring Bodies are supposed to be easily visible on the regular H-E stain, but with the chrome-hematoxylin-phloxin stain they should be dark greyish-blue, irregular spots

26
Q

What tissue is this from?

What are the characteristic features you see of that tissue?

A

Pineal Gland

There are a few places of brain sand / acervulus

Also see pinealocytes with large, oval, granular nuclei and prominent nucleoli

Plus interstitial glial cells between pineaolocytes and blood vessels

27
Q

What tissue is this?

What parts and cell types do you see?

A

Thyroid Gland

Look at answer image for identification

28
Q

What tissue is this?

A

Thyroid Gland again

This time the image says “Autoradiographia”

29

What layer of that tissue makes up the majority of the image?

What is the thinner layer towards the bottom of the image?

And the lower-most layer?

A

Adrenal Cortex

(image is upside-down from the normal order)

Most of the image is Zona Fasciculata

Below that is Zona Glomerulosa

Then there’s the Capsule

31
Q

What layer makes up the lower half of the image?

What layer is the top-right corner?

A

Adrenal Gland Cortex

Lower half of image is Zona Fasciculata

Top-right = Zona Reticularis

32

What are the important layers/cells?

A

Adrenal Gland

Shows Zona Reticularis and Medulla

Notice the ganglion cells and chromaffin cells in the medulla

33
Q

What tissue is this from?

What formation do you see?

A

Adrenal Gland Medulla

See the sinusoid capillary, feel the sinusoid capillary, know the sinusoid capillary

probably some other important stuff too

34
Q

What tissue is this?

What stain?

What are the different layers of lining called?

A

Peripheral Nerve

Osmium Tetroxid stain

Outermost lining = epineurium, then there’s perineurium over each of the two balls, and endoneurium over individual nerve fibers

35
Q

What is this tissue?

A

Peripheral Nerve

36
Q

What’s this round blob here?

A

Peripheral Nerve

37
Q

Can you spot the peripheral nerve in this one?

A

Go on, find it!

This is a scalp skin slide

38
Q

What tissue is this?

A

Spinal Ganglion with Pseudounipolar Neurons

Very large round cell bodies with nuclei that are poorly stained except for their nucleoli

Perikarya should be basophilic due to Nissl substance

Note also the:

Satellite cells around the neurons

Schwann cells whose nuclei are among the nerve fibers

39
Q

Wtf is this thing

A

Another example of pseudounipolar neurons but with silver staining

40
Q

What tissue is this?

What stain?

A

Autonomic Ganglion with Multipolar Cells

Silver Nitrate Impregnation

The nuclei are “negatively stained”

41
Q

What is the paler mass here?

A

This is a pancreas slide

This is labeled as a Vegetative / autonomic ganglion and does not really look like the alpha/beta cells of islets of Langerhans

42
Q

What slide is this?

What stain?

A

Spinal Cord Cross-Section

I think this only shows half of the spinal cord, with the dorsal horn being in the lower half of the image (flipped from how you probably normally would draw it)

Cajal Silver stain

43
Q

What are the most prominent type of cells you see here?

What slide might they be in (tissue and stain)

A

(Multipolar) Motor Neurons

Taken from the ventral horn of the spinal cord

Nissl stain (with cresyl-violet), which gives the rER a bluish-purple (Nissl Substance)

44
Q

What tissue is this?

A

Cerebral Cortex

Remember the 6 layers

(could be worse, i mean it’s less layers than are in a burrito from taco bell)

Note that the image just has one pyramidal layer and also a ganglionic layer, but our department usually calls these the outer and inner pyramidal layers

45
Q

What tissue is this image from?

What stain?

A

Cerebral Cortex

Bielschowsky Stain

Those 6 layers are more visible with this stain

Note that the image just has one pyramidal layer and also a ganglionic layer, but our department usually calls these the outer and inner pyramidal layers

46
Q

What tissue is this from? What stain?

What notable cell is here?

A

Cerebral Cortex - Golgi stain

Pyramidal Cell

(maybe even a Betz cell, but hard to tell when it’s zoomed in)

47
Q

What tissue is this from?

What is the light layer at the bottom and the darker layer above that?

What are the big dark cells at the border of those 2 layers?

A

Cerebellum

Light layer = Molecular Layer

Dark layer = Granule Cell Layer

Big cell in the border = Purkinje Cell, which make up a Purkinje Cell Layer aka Stratum Ganglionare

48
Q

What tissue is this from? Stain?

What is the layer at the bottom and the darker layer above that?

What are the big dark cells at the border of those 2 layers?

A

Cerebellum - Bielschowsky stain

Light layer = Molecular Layer

Dark layer = Granule Cell Layer

Big cell in the border = Purkinje Cell, which make up a Purkinje Cell Layer aka Stratum Ganglionare

49
Q

What type of cell is this?

What stain?

A

Purkinje Cell (in cerebellar cortex)

Golgi stain

50
Q

There are 2 types of astrocytes here to find

A

It’s the fibrous and protoplasmic astrocytes

This is a Cajal gold impregnation stain

51
Q

What is the green microsoft paint arrow pointing at?

A

a Meissner Corpuscle

52
Q

This thing is fucking crazy, what is it?

A

A Pancreatic Paccinian Corpuscle

So your pancreas can feel vibration

53
Q

What tissue is this?

What stain?

A

Motor End Plate

Acetylcholinesterase Histochemistry stain

You can lightly see the muscle fibers, while the dark splotches are the motor end plates

54
Q

What tissue is this from?

There’s a ton of shit here, be able to find it

A

This is the Eye with the sclera, iris, etc

Make sure you know the Canal of Schlemm

55
Q

What’s this tissue from?

What are all these layers?

56
Q

What tissue is this from?

What stain?

A

Cochlea

Semithin Section, Toluidine Blue stain

57
Q

What tissue is this from?

Can you identify some of the cells?

A

Organ of Corti

This image has all the important shit, but our school still tries to teach us all the names of the douchebags who wanted some phalangeal cells in the ear named after them like Hensen, Deiter, Claudius, and Boettcher

Corti was the only one of those dudes who mattered

58
Q

What tissue is this from?

A

Lacrimal Gland

May be easy since this deck is separate from most of the other ones with gland cards, but it’s similar to parotid gland and pancreas

Although it’s exclusively serous, it has much less adipose than the parotid gland, and of course it doesn’t have islets of Langerhans
