Study Notes

Epithelial Tissue Characteristics

Epithelial tissue is avascular, lacking blood vessels.
It covers the exterior surfaces of the body.
It lines internal closed cavities.
It forms the secretory portion of glands and their ducts.
It constitutes the receptors of certain sensory organs.
Epithelial tissue exhibits diverse types.
Cells are arranged in sheets.
Cells possess intercellular junctions (junctional complexes).
Cells display distinct surface domains: apical (free), lateral, and basal.
Cell properties are determined by specific membrane proteins.
Epithelial tissue rests on a basal lamina, a non-cellular, protein-polysaccharide-rich layer.

Types of Epithelial Tissue

Further detail on types of epithelial tissue requires additional information (e.g., squamous, cuboidal, columnar, stratified, simple).

Basic Tissue Types

Basic tissue types include epithelial, connective, muscle, and nervous tissues.

Questions

Name the four basic tissue types.
