1
Q

What tissue is this? How is it arranged?

A

Smooth Muscle, Longitudinal Section

Nuclei appear longer in longitudinal sections, don’t mix up with tendon! These SMC’s are more strongly stained and the nuclei don’t run in such clear lines as they do in the tendon

2
Q

What is the slide of? How was the tissue cut?

A

Smooth muscle cells in cross section

3
Q

What type of tissue is this?

What type of section?

A

Striated Muscle

Longitudinal Section

Q

What tissue is this?

(Unusual stain, not part of normal slides)

A

Striated muscle, longitudinal section

Iron Hematoxylin stain

Longitudinal Section

7
Q

What tissue is this?

A

Cardiac Muscle

8

Elastic fibers of Tunica Media are shown

with Resorcin Fuchin stain

9
Q

What type of tissue?

10
Q

What’s the structure on the top right?

And the one on the bottom left?

A

Top right = muscular artery

Bottom left = vein

11
Q

-has internal and external elastic membranes

Resorcin Fuchsin stain

12
Q

What structure is this?

What stain?

(not normal slide)

A

Muscular artery

Iron Hematoxylin

13
Q

What type of structure is this?

A

Muscular Venous Plexus (Pampiniform)

14
Q

What do you see in the middle of this image?

A

Venules,

including a longitudinal section of the vessel wall

15
Q

1?

2?

3?

A

1: Arteriole
2: Venule
3: Capillary

16
Q

There are capillaries, arterioles, and venules here. Find them!

A

Not gonna label all these myself

17
Q

What structure is this between the two blood vessels?

A

Carotid Glomus (Glomus Caroticum)

Wasn’t in the histo classes as far as I remember, but who knows what they’ll do for competition

18
Q

What are the two non-RBC cells in this image?

What stain?

A

The paler top one is a neutrophil

Below that is an eosinophilic granulocyte

Stain is Pappenheim blood smear

19
Q

What are the 3 non-RBC cells in this picture?

A

Top one is neutrophil

Below that is basophil

Bottom right is lymphocyte

20
Q

What is the non-RBC in the picture?

A

Monocyte

21
Q

What two non-RBC cells are seen in this image?

A

Lymphocytes

the smallest WBC’s, they can be around the same size as an RBC (6 to 8 micrometers) to almost twice as large (11-12 micrometers)

22
Q

What tissue is here?

(not a typical department slide)

A

Bone Marrow

23
Q

What organ is this?

What stain?

A

Lymph Node

Azan

24
Q

What organ is this?

What stain?

(not a typical department thing, can probably forget it..)

A

Lymph Node

Silver stain, showing fibers

25
Q

What organ is this?

What is the lighter-colored region to the right?

What is the general darker region to the left of that?

A

Lymph Node

To right is the capsule

Darker region is cortex with follicles

26
Q

This is the lymph node

The dark cluster of cells in the middle and top is the cortex

Towards the bottom of the image you can see a capsule

What is the paler region between the cortex and capsule?

A

The marginal sinus

Image has it labeled as subcapsular

27
Q

This is in the lymph node

What general region of the node is this?

A

The Medulla

has plasma cells, macrophages and B-lymphocytes

28
Q

What organ is this?

A

Spleen

  • has lymph follicles and a capsule
  • does not have distinct cortex/medulla structure as in lymph nodes
  • does not have pits, muscle and adipose tissue as in tonsils
29
Q

This is the spleen

What stain is this?

What are the empty spaces called?

A

Washed spleen

What looks like empty spaces are sinusoids

30
Q

What organ is this?
