Identify Its got lots of big purple granules

Identify

• Its got lots of big purple granules • It’s a basophil

What layer is indicated

• First… what are you looking at in general? – A large vein… you know because the tunica media is really SMALL • Remember that the tunica adventitia of some large veins can have longitudinally oriented smooth muscle… this is the case in this image so this is the tunica adventitia

Identify

• Myelinated Axons

Identify

• Hints: – Shape of nucleus – Color of cytoplasm – Neutrophilic band/stab cell

Identify

• First, what type of vessel? – lumen/wall thickness ratio Artery – Tunica media has TONS Of muscle – Also you can see the internal elastic lamina – MUSCULAR/MEDIUM Artery

Identify

• Basophilic erytrhoblast

What is predominant below the red line

• Bullseye appearance of the cell • GANGLIA

Identify

• Eosinophilic myelocyte

Identify

• Reticulocyte – Has the RNA fragments still in it

Identify

• medium vein – You know it’s a vein because the lumen got all mashed up and it doesn’t have a very thick wall – You know its medium because of its relative size

Identify

• Neutrophilic stab cell – You know because it has a horseshoe shaped nucleus band cell and that its cytoplasm is salmon colored neutrophil

Identify

• Lymphocyte – Because its not much bigger than RBCs – And its got a THIN layer of cytoplasm around it

Identify

• Orthochromatophilic erythroblast – You know because it’s the same color as the RBC – And the nucleus is condensed

ID the red arrow

• Eosinophilic metamyelocyte – Eosinophilic because its got a shitload of bright red/pink granules – Metamyelocyte because its got a kidney shaped nucleus

Identify

• A happy neutrophil – Happy because you all got it right
