Histology IntroOh, Say, can you see?
Organs are made of lots of tissues!
Muscle: Cardiac
Muscle: Smooth
Muscle: Skeletal
Epithelial: Skin
By definition, this tissue exists at the outside edge… Look for it! The “Free” surface = apical
Free faces outside or lumen of a tube The “attached” surface = basal
Finding Epithelium
Simple: Stratified:
Determine the number of layers
Squamous Cuboidal
Columnar
… and shape
Pseudostratified…
Transitional…
…or something else…
Comparing epithelium
Simple columnar Stratified squamous
More epithelium…
Simple cuboidal
Neuron histology
Nerve histology
Loose (areolar)
Connective Tissue Types
Dense Connective Tissue
Dense Regular Tendons, ligaments
Dense Irregular Joint capsules, skin,
hollow organs
Connective Tissue
Adipose (fat) Blood
Connective tissue
Cartilage
