The Four Basic Tissue Types

1) Epithelial

2) Muscle

3) Nervous

4) Connective

Epithelial Tissue:

Cells, Extracellular Matrix, Functions

Cells: Aggregated polyhedral cells

Extracellular Matrix: Very small amount

Functions: Lining of surface of body or body cavities; glandular secretion

Muscle Tissue:

Cells, Extracellular Matrix, Functions

Cells: Elongated contractile cells

Extracellular matrix: Moderate amount

Function: Movement

Nervous Tissue:

Cells, Extracellular Matrix, Functions

Cells: Intertwining elongated processes

Extracellular Matrix: None

Function: Transmission of nervous impulses

Connective Tissue:

Cells, Extracellular Matrix, Functions

Cells: Several types of fixed & wandering cells

Extracellular matrix: Abundant

Functions: Support; protection
