Fibrous Connective Tissues
There are lots of varieties. As you can see here, the top example (Dense Regular) is organized in a linear fashion and works like a rope for your body and makes up tendons and ligaments. The middle one (Dense Irregular) has a more woven arrangement and is usually around the outside of organs and helps prevent them from expanding or stretching too far. The bottom example (Loose Fibrous) is more of a net with more empty space and less fibers. It is the weakest of the one pictured here and often is used to fill spaces in the body.
