What Role Do Joints Play?

If your leg had only one long bone, how would you get out of bed?
Luckily, your leg has many bones so you can move it easily. A joint is a place where two bones come together. Joints allow bones to move in different ways. You have two kinds of joints:
immovable and movable.

Immovable Joints Immovable joints connect bones but allow little or no movement. The bones of the skull are held together by immovable joints.

Movable Joints Most joints are movable. They allow the body to make many different movements such as those shown in the picture. The bones in movable joints are held together by ligaments, which are made of strong connective tissue.

And the reason they're confusing is because they don't sound anything like they look. This is a common problem in English. But WHY? Because English is not a phonetically-spelled language. In other languages, the way a word looks is the way it sounds. In English, not so much! Now, I need to say something before started. This lesson is about memorization . I'm sorry but sometimes memorizating is a mandatory stuff. If you want to speak like an American you have to say it like this. Why? I don't know. I'm sorry to tell you that. There's no answer...
