Connective tissue
Nervous tissue
Muscle tissue
Epithelial tissue
Covers body surfaces or lines a body cavity
Connective tissue
Connects, binds, and supports
Nervous tissue
Controls body functions, initiates and transmits impulses
Muscle tissue
Contracts to produce movement
Epithelial tissue: simple
Single layer of cells
Epithelial tissue: stratified
Two or more layers of cells
Epithelial tissue: pseudostratifed

Epithelial tissue: squamous
Flat, scale like cell with flattened nucleus
Epithelial tissue: cuboidal
Boxlike cell with round nucleus
Columnar
Tall, column shaped cell with elongated nucleus near base
All epithelial tissue rest on
Basement membrane
