How do synovial joints differ from fibrous and cartilaginous joints?

I’m trying to wrap my head around the different types of joints in the body. What are the key differences between synovial, fibrous, and cartilaginous joints in terms of structure and function? Why does the body need all three types, and where are some common examples of each found?

Synovial joints are the most mobile-they have a joint cavity filled with fluid, like your knee or shoulder. Fibrous joints are basically immovable, like the sutures in your skull.

Cartilaginous joints allow for a little movement and are connected by cartilage, like the discs between your vertebrae or the pubic symphysis.

The fluid in synovial joints helps reduce friction and nourish the cartilage. That’s why injuries to these joints can be so painful-they’re complex and take a lot of stress.
