4. Connective Tissues
• Functions: Bind structures together,
support, transport, protection
• Contains few cells and an abundant
intercellular matrix (Matrix = space
between cells)
• The matrix is filled with fibers that are
produced by the cells, including collagen
fibers and elastic fibers
5. Types of connective tissue
1. Loose (areolar): packing material.
Attaches skin to underlying tissues. Fills
the spaces between muscles.

1. Loose (areolar): packing material.
Attaches skin to underlying tissues. Fills
the spaces between muscles.
2. Adipose tissue: Fat. Provides energy
storage, cushioning around organs, and
insulation

3. Dense fibrous: Forms tendons (connect
muscle to bone) and ligaments (connect
bones to each other)

4. Elastic: Can stretch and then return to
normal length. Vocal cords, ligaments
between vertebrae

5. Cartilage: Contains protein chondrin,
which is stiff but flexible

5. Cartilage: Contains protein chondrin,
which is stiff but flexible
a. Hyaline cartilage: Found at end of long
bones, where ribs attach to sternum,
rings of trachea, fetal skeleton

a. Hyaline cartilage: Found at end of long
bones, where ribs attach to sternum,
rings of trachea, fetal skeleton
b. Fibrocartilage: strong shock absorber.
Found in pads between vertebrae and in
the knee

b. Fibrocartilage: strong shock absorber.
Found in pads between vertebrae and in

c. Elastic cartilage: more flexible. Found
in external ear, epiglottis
13. Types of connective tissue
6. Bone: Most rigid connective tissue. Fibers
are surrounded by calcium salts.
Provides framework for body.

6. Bone: Most rigid connective tissue. Fibers
are surrounded by calcium salts.
Provides framework for body.
7. Blood: Red and white blood cells are
suspended in a liquid matrix (plasma).
Transports oxygen and nutrients
