Cell Junctions | Structural Features of Epithelia | Types of Epithelial Tissue | Glandular Secretion | Glands |
---|---|---|---|---|
What is a Desmosome?
An anchoring junction where cadherins anchor lateral surfaces of adjacent cells together.
|
What is the Basement Membrane?
Composed of basal lamina that attaches epithelium to deeper reticular lamina.
|
What is Keratinized Stratified Squamous Epithelium?
The top layers of these cells are dead and they function as dry protection against abrasion.
|
What are Hormones?
The secretions of endocrine glands.
|
What is a Gland?
A structure made up of one or more cells modified to synthesize and secrete chemical substances.
|
What is a Gap Junction?
An intercellular passageway that allows ions to pass between adjacent cells.
|
What is the Lumen?
The free space of an epithelial cell.
|
What is Ciliated Psuedostratified Columnar Epithelium?
Tall, narrow apical cells with cilia. One lay of cells but they may appear to have more than one layers.
|
What is Holocrine Secretion.
Type of glandular secretion where the cell is destroyed as it releases its product.
|
What is a Exocrine Gland?
Gland with duct that opens directly or indirectly to external environment.
|
What is a Tight Junction?
A structure that separates cells into apical and basal compartments.
|
What is a Cell Junction?
A specialized intercellular connection between epithelial cell membranes.
|
What is Simple Cuboidal Epithelium?
Epithelium with one layer of box shaped cells, found lining the renal tubules.
|
What are Exocrine Gland Secretions.
Mucous, sweat, saliva and breast milk.
|
What is a Serous Membrane?
These glands produce watery, enzyme rich secretions.
|
What is an Adherens Junction?
These junctions influence the shape and folding on the epithelial tissue.
|
What is the Apical Surface?
The exposed surface of an epithelial cell.
|
What is Non-Keratinized Stratified Squamous Epithelium?
Epithelium that functions for moist protection against abrasion; found lining the human oral cavity and esophagus.
|
What is Merocrine Secretion.
Secretion where the cell itself remains intact and the contents are released through exocytosis.
|
What is a Endocrine Gland?
Ductless gland that secretes into surrounding tissue and fluid.
|
What is an Anchoring Junction?
A cell junction that helps stabilize epithelial tissue.
|
What is the Basal Lamina?
This structure provides an attachment site for epithelium, separating it from underlying connective tissue.
|
What is Transitional Epithelium?
This type of Epithelium is found in the human urinary system and functions to provide stretching and distension.
|
What is Apocrine Secretion.
Secretion where the apical portion of the cell is released as well.
|
What is a Mucous Gland?
Glands that produce secretion rich in glycoprotein mucin.
