*Make sure you are on the right part of the slide!

The stratified squamous is the multiple layers at the top!

(It’s the top layers of skin!)

**The “bulls-eye” is not one cell. It is a group of cells, with a canal in the middle.

Compact Bone (ground)

*Be careful! Make sure you focus on some of the pink spongy bone, NOT only on the bone marrow- see diagram.

Blood (liquid tissue)

(Label red blood cells,white blood cells,

platelets)

**Striations are hard to see- they do NOT go the same direction as the cell- they go perpendicular (90 degrees) like markings on a ruler.

***Notice they have more than one nucleus per cell!

Skeletal muscle

(Label one cell, nucleus and striations)

one cell

Striations (lines)

**There are no striations on smooth muscle cells. If you get a slide that says “teased,” they were pulled out so you can see individual cells.

**Striations are hard to see- they do NOT go the same direction as the cell- they go perpendicular (90 degrees) like markings on a ruler.

***The intercalated discs allow communication between cells. One cell is from one disc to another- they define the lateral borders.

**Glial cells are cells that help and support the neurons.

Neuron

(Label one cell, nucleus, cell membrane, axon, glial cells)

The salmon/pink colored cells are red blood cells. They may be in clumps on our slide.

The purple cells are dyed white blood cells. There are MANY more white blood cells than normal (in a normal slide, you only see 2 or 3) Leukemia is cancer of the white blood cells.
