| Cuboidal | Box-shaped or cube-shaped cells; structure is ideal for secretion/re-absorption |
| Columnar | Tall, rectangular-shaped cells; structure is ideal for storage/absorption or protection |
| Simple | Term used to describe only ONE layer of cells |
| Stratified | Term used to describe 2 or more layers of cells |
| Pseudostratified | Term used to describe a tissue that appears to have more than one layer, but is really only one layer; FAKE layers |
| Basal surface | Part of epithelial tissue that is at the bottom of the tissue and attached to the basement membrane |
| Free surface | Part of the epithelial tissue that is exposed to an open area (either the external environment or to the inside of a hollow organ). |
| Endocrine Glands | Glandular tissue that releases its products (hormones) directly into the bloodstream |
| Exocrine Glands | Glandular tissue that releases its products (mucus, saliva, oil, wax, sweat, digestive enzymes, milk) directly onto a surface |
| Transitional | Term used to describe cells that have the ability to change shape from columnar/cuboidal to squamous/flat |
