1) Epithelial
2) Connective 3) Muscle 4) Nervous What are these? |
tissue types
|
|
|
What are these?
• By cell shape & number of layers • If you determine the shape and layers, you know the type |
cell classifications
|

|
What cell shape is this?
Square, with a round nucleus in the center, looks like a box with a dot in the middle |
cuboidal
|
|
|
What cell shape is this?
Rectangle, vertical with the nucleus at the bottom in the center, looks like Lego with only one dot on the bottom |

How many layers in the stratified layer type?
|
several
|
|
|
How many of the epithelial cell types lay on a basement membrane?
|
all
|
|
|
What cell type is this?
• Lung air sac • 1 cell thick • Diffuses oxygen • Sits on a basement • Round |
Simple squamous epithelial
|
|
|
What cell type is this?
• 1 cell thick • Sits on a basement • Kidney tubules • Urine |
Simple cuboidal epithelial
|
|
|
What cell type is this?
• Digestive stomach area • Sits on a basement • Stomach, small intestine, large intestine |
Simple columnar epithelial
|
|
|
What cell type is this?
• Has cilia on top • Looks stratified but its not • Basement • Respiratory tract • Trachea • Nasal • Looks like a mountain range with hair on top • Round nucleus |
Pseudo stratified columnar epithelium
|
|
|
What cell type is this?
• Protective • Esophagus • Basement • Looks like oblong smooth rocks stacked |
Stratified squamous epithelial
|
|
|
What cell type is this?
• Bladder Can accommodate the increasing urine in the bladder • 6 layers to 3 layers as bladder fills • Slides show empty bladder • Dome shape • Basement • Look like round circles stacked neatly with nucleus in the center |
Transition epithelium
|
|
|
Are embedded in an extracellular matrix?
|
Connective tissue
|
|
|
Fibers are present (collagen & elastic)
|
Connective tissue
|
|
|
• Holds skin to muscle as we saw with dissected rats.
• Attaches skin to underlying muscle. • Packing material surrounds blood vessels. • Looks like river currents with cross strands and dots. |
Arelor CT
|
|
|
• Nucleus pushed to the side by fat globules
• Looks like roundish squarish shapes stuck together with dots on the side of each shape |
Adipose (fat) CT
|
|
|
• Strongest tissue
• Tendons • Collagen fiber • Fibroblast • Looks like long flowing river strands with flattened pancake looking nucleuses |
Dense Rectangular CT
|
|
|
• Bones
• Nose • Most common type of cartilage • Fibers that you can’t see • Very fine collagen • Chondrates (cell name) • Lacuna • Cavity that contains the cell • Looks like a cell in a bubble (nucleus, in a round membrane that is in a bubble). |
Hyaline cartilage
|
|
|
• Ears
• Fibers with black strands • Black staining elastic fibers • Elastic fiber • Looks like black lines and dark areas around hyaline cartilage (cell in a bubble) |
Elastic cartilage
|
|
|
• Color on this one, that’s how you memorize it
• In vertebral discs • Discs between the vertebra • Looks like flat oval pancake with nucleus in the middle |
Fibro cartilage
|
|
|
• Red blood cells all over
• A few white blood cells • White blood cells are much bigger than the red • No nucleus • Looks like a sea of round small dots with a few bigger irregular looking cells in the soup. |
Blood
|
|
|
• Living tissue
• Osteocyte (bone cell) • Central canal • Contains blood vessels & nerves • Looks like petrified tree stocks |
Bone
|
|
|
• Looks like an uneven propeller
• Cell processes |
Nervous tissue
|
|
|
• Voluntary
• Striated • Proteins that allow muscles to contract • Multi nucleated • Looks like a 2 by 4 with vertical lines every centimeter with the nucleuses squished on the top and bottom |
Skeletal muscle
|
|
|
• Striated (2 by 4 with horizontal lines every centimeter)
• Involuntary • Uni nucleated • All cells contract at once (intercalated disc) • Allows the stimulus to contract spread from one cell to another to speed the process. • Looks like striated (2 by 4 with horizontal ticks, train tracks), but with junctures (the tracks branch at intersections) |
Cardiac muscle
|
|
|
• No striations
• Uni nucleated • Intestines, bladder, blood vessels • Involuntary • Looks like big flat pancakes with nucleus in the center |
Smooth muscle
|
