Tissues are groups of similar cells that work together to perform a common function. This area of biology is called Histology, the study of tissues. The four types of tissues in the human body are 1) Epithelial, 2) Connective, 3) Muscle, and 4) Nervous.

I. EPITHELIAL TISSUE

A. General Characteristics

1.  1.“Free” space or surface
2.2.  Basement membrane
3.3.  Mostly “avascular”
4.4.  Covers external and internal body surfaces
5.5.  Lines digestive, respiratory, reproductive and urinary tracts
6.6.  Lines internal cavities and passageways

B. General Functions

•1.  Protection
•2.  Controls permeability
•3.  Sensation
•4.  Produces special secretions

C. Classification of Epithelial Tissue

1. Number of cell layers

a. Simple
b. Stratified

2. Cell shape

a. Squamous
b. Cuboidal
c. Columnar

 

 

 

 

 

EXAMPLES OF EPITHELIAL TISSUE:

----------------------------
2.  Simple cuboidal epithelium
----------------------------
3.  Simple columnar epithelium
----------------------------
4.  Pseudostratified ciliated columnar epithelium
----------------------------
5.  (Stratified) Transitional epithelium
----------------------------
6. Stratified squamous epithelium

II. CONNECTIVE TISSUE

A. General characteristics

•1.  Extremely diverse group
•2.  All contain (a) specialized cells, (b) protein fibers and (c) ground substance
•3.  Extracellular matrix
•4.  Matrix ranges from fluid to loosely knit fibers to hard calcium phosphate crystals

B. General functions

1. Binds structures and fills spaces
2. Support
3. Protection
4. Transport of materials
5. Stores energy

 

 

 

 

EXAMPLES OF CONNECTIVE TISSUE (CT):  *Know cell types associated with each, specific modifications and locations*

1.  Areolar/loose CT

2.  Adipose

3.  Dense/white fibrous

4.  Cartilage

a. Hyaline

b. Elastic

c. Fibrous

5.  Bone

a. Compact

 

b. Spongy/cancellous

 

6.  Blood

 

 

 

 

 

 

 

III. MUSCLE TISSUE

A. Function - provides movement

EXAMPLES OF MUSCLE TISSUE:

NAME DESCRIPTION LOCATION NERVOUS CONTROL
 

Skeletal muscle

 

      
 

Cardiac muscle

 

      
 

Smooth muscle

 

      

IV. NERVOUS TISSUE

A. Function- 

B. Cell types

1. Neurons - 

2. Neuroglia -
