Epithelial- transportation of materials and protection of underlying tissues

Nervous- transmit nerve impulses

Connective- provides structural support for the tissues and organs of the body


Muscular- skeletal or cardiac muscle

Epithelial- cell shape and arrangement

Nervous- neurons ad neuroglia

Connective- holds body together

Specializations of epithelia:

the movement of fluids over the epithelial surface, providing protection and lubrication

the movement of fluids through the epithelium, to control permeability

the production of secretions that provide physical protection or act as chemical messengers
