Term
Avascular
Definition

Lacking blood vessels; characteristic of epithelial tissue.

Term
Basement Membrane
Definition

A layer of carbohydrates and proteins to which the deepest or most superficial epithelial cells are attached.

Term
Ciliated Pseudostratified Columnar Epithelium
Definition
  • Lines respiratory tract; parts of the reproductive tract
  • Function: protection; secretion; movement of mucus and sex cells
Term
Columnar Epithelium
Definition

Epithelium consisting of one or more cell layers, the most superficial of which is composed of elongated and somewhat cylindrical cells projecting toward the surface.

Term
Cuboidal Epithelium
Definition

Epithelial tissue consisting of one or more cell layers, the most superficial of which is composed of cells of equal height and width.

Term
Epithelial Tissue
Definition
  • membranous tissue covering internal organs and other internal surfaces of the body.
Term
Meninges
Definition

     3 membranous layers which line the posterior body cavity (brain and spinal cord)

Term
Pseudostatified Columnar Epithelium
Definition

Epithelial tissue, often ciliated and columnar, in which all of the cells rest upon the basement membrane.  However, not all cells touch the free surface.  The nuclei appear staggered.

Term
Simple Columnar Epithelium
Definition
  • Lines gastro-intestinal tract; the ducts of many glands
  • Function: secretion; absorption
Term
Simple cuboidal epithelium
Definition
  • Function:  Secretion; absorption
  • Lines Kidney tubules; ducts of many glands; surface of ovaries
Term
Simple squamous epithelium
Definition
  • Location:  line air sacs of lungs; blood vessels; heart
  • Thin flat cells, tightly joined
  • Filtration; diffusion; osmosis
Term
Squamous
Definition

epithelium consisting of one or more layers of scalelike cells.

Term
Stratified Epithelium
Definition

Epithelium made up of a series of layers, the cells of each varying in size and shape.

Term
Stratified Squamous Epithelium
Definition
  • Location:  Lining of esophagus; mouth; vagina; epidermis
  • Function: protection from abrasion & desication in keratinized form.
  • keratinized or non-keratinized
  • multiple layers of scale-like cells
Term
Transitional Epithelium
Definition
  • epithelial cells that may be flattened or cuboidal; found in the urinary bladder and in the first expansion of the ureters as they leave the kidneys
  • these cells have the capacity to stretch and flatten so the calyx and bladder can expand.
Term
free surface
Definition

Outer/Inner area that the most superficial or deepest cells in epithelial tissue are exposed to.

Term
simple epithelium
Definition

Epithelium made up of one layer of cells.
