A collection of identical cells working together with a substance in between them serves a specific function in living beings with many cells. Animal Tissues can be grouped into four categories: epithelial tissue, connective tissue, muscle tissue, and neural tissue.
Epithelial Tissue
- This type of tissue acts as a protective layer or lining for different parts of the body.
- It has an exposed surface that comes into contact with body fluids or the outside world.
- Covering tissues are further divided into two kinds: simple covering tissue and compound covering tissue.
- Examples include the skin, the linings of body openings, and various ducts and tubes.
Connective Tissue
- Connective tissues connect and provide support to different parts of the body, including organs and tissues.
- They encompass soft supporting tissues as well as specialized types like cartilage, bone, fat tissue, and blood.
- In all supporting tissues except blood, cells produce collagen or elastin fibers.
- These cells also release modified sugars that create a framework between cells and fibers.
- Supporting tissue can be classified into three forms: dense supporting tissue, specialized supporting tissue, and loose supporting tissue.
Muscle Tissue
- Muscle tissue is composed of small, elongated cells that together form muscles.
- Muscles are responsible for all body movements.
- There are three types of muscles: skeletal muscles for voluntary movements, smooth muscles for involuntary actions, and cardiac muscles for the heart.
Neural Tissue
- Neural tissue primarily controls how the body responds to changing conditions.
- Neural tissue consists of two types of cells: glial cells and neurons.
