Connective tissue
Muscle tissue
Neural tissue
Characteristics of Epithelial Tissue Very little space between the cells
Arranged in sheets or layers
Have an apical surface and a basal surface
basal surface is attached to the basal lamina
avascular (lack blood vessels)
Are highly regenerative

Specializations of epithelial tissue Microvilli= Increased surface area
Sterocilla= receptors for hearing and balance
Cillia= Movement of extracellular substances

Maintaining the Integrity of the Epithelium Intercelluar Connections= Intercelluar cement, junctions, interlocked infoldings
Attachment to the basal lamina
Maintenance renewal= Division of germinative cells near the basal lamina

Simple Epithelia One layer
Stratified Epithelia Multiple layers
Sqamous Thin flat cells
Cuboid Height= Width
Columnar Height several times the width
Simple Squamous Epithelium Functions: Friction Reduction
