Four Major Types of Tissue?

Definition




 

epithelial, connective, muscle & nerve

Term

 

 

Epithelium Cellularity

Definition

~usually packed together forming continuous sheets of cells with little extracellular fluid


~bound together at many points by cell junctions such as desmosomes or tight juctions

 

Term

 

 

Epithelium Polarity

Definition

Epithelium has two surfaces..

 

1) apical surface - exposed to either the exterior of the body or a cavity

 

2) basal surface - the deepest surface which rest on a basement membrane

Term

 

 

Epithelium has

conncective tissue support..

Definition

~all epithelium rest on a membrane called basement membrane - 2 layers

1) basal lamina - primarily protein made by the cells.

2)  reticular lamina of connective tissue

 

 

Term

 

 

Characteristics of the epithelium

Definition

~Avascular - it has no blood supply on its own, recieves nourishment from underlying tissue.

 

~has nerve supply

 

~regenerative

Term

 

 

 

Locations of the Epithelium

Definition

~Body Coverings (surface of body)

 

~lines internal cavities

 

~Glandular epithelium - lines the secretion portion of glands

Term

 

 

 

Functions of the Epithelium

Definition

~Protects the body (skin)

~Absorption (intestinal cells)

~Filtration (kindeys)

~Secretion (glands)
