Fibrous joints are important for keeping our skeleton strong and working properly. Here’s a simple breakdown of what they are and how they help us:

1. Types of Fibrous Joints:

   • Sutures: These are found in our skulls. They don’t move much, but they allow our skulls to grow when we are young.
   • Syndesmoses: These joints, like the ones between our tibia (shin bone) and fibula (calf bone), let us move a little bit. They help keep our legs stable while still allowing some bending.
   • Gomphoses: Think of these as peg-and-socket joints. They connect our teeth to their sockets in the jaw. They don’t move much, but they hold our teeth in place really well.

2. How They Help Us:

   • Stability: Fibrous joints are made of strong tissue. This makes them very stable and helps hold our bones together.
   • Protection: These joints protect important parts of our bodies. They help stop our bones from dislocating or getting hurt.
   • Growth: In sutures, they allow our skulls to grow during our early years. On average, our skulls grow about 0.5 mm per year until we are fully grown.

In short, fibrous joints are key to keeping our bones stable and safe as we grow up and go through different stages of life.
