All cells in the body are specialised in some way. Each type of cell has a specific job to do. There are about 200 different types of cells in our bodies. These types of cells form all of the different types of tissues. There are 4 broad categories of tissues, classified according to their function and characteristics. Each category has many variations; tissues that serve many different purposes.

3. Tissues
A tissue is a group of cells that are similar in structure and function
Four basic types of tissue:
Epithelial tissue
Connective tissue
Muscular tissue
Nervous tissue

4. Epithelial tissue Function Characteristics Examples:
Covering or lining
Characteristics
Cells closely joined together
Various shapes – thin and flat (squamous), column- shaped (columnar), cube-shaped (cuboidal)
Smooth surface
Examples:
outer layer of skin
outside lining of many organs
inside lining of the stomach, heart and intestines

5. Connective tissue Function Characteristics Examples Bone & cartilage
Provides support
Holds body parts together
Characteristics
Cells spaced apart, forming a matrix
The matrix is filled with
non-cellular material
Examples
Bone & cartilage
Tendons & ligaments
Fat storage tissue
Blood

6. Muscular tissue Function Characteristics
Can respond to stimuli and contract (become shorter)
Facilitates controlled movement
Characteristics
Skeletal muscle (voluntary muscle)
Cells are shaped like long fibres
Cells are striated (striped)
Involuntary muscle
Cells are more round in shape, with pointy ends
Cells are smooth or not striated
Cardiac muscle
Cells are branched fibres

7. Muscular tissue

8. Nervous tissue Function Characteristics Examples
Send signals or electrical impulses from one cell to another
Allows us to perceive and respond to the environment
Characteristics
Have a cell body, dendrites
and an axon
Are spindly or thread-like
in shape
Examples
Brain, spinal cord, nerves
