The places where two or more bones meet are called joints. Bones are held together by strong bands of tissue called ligaments. There are several kinds of joints in your body. The joints in the skull are an example of immovable joints. The curved bones in a skull join together in what look like cracks. These bones do not move.

1. What do you call the places where two or more bones meet?





2. How would you describe a ligament?





3. What is an example of an immovable joint?






Level#2

The places where two or more bones meet are called joints. Bones are held together by strong bands of tissue called ligaments. There are several kinds of joints in your body. The joints in the skull are an example of immovable joints. The curved bones in a skull join together in what look like cracks. These bones do not move. The joint between your skull and neck is a pivotal joint. This type of joint allows your head to nod up and down. It also allows your head to move from side to side. Your hip and shoulder joints are examples of ball-and-socket joints. These joints allow bones to move in several directions.

1. What type of joint is found between the skull and neck and what does it allow you to do?

The joint between your skull and neck is a pivotal joint. This type of joint allows your head to nod up and down. It also allows your head to move from side to side. Your hip and shoulder joints are examples of ball-and-socket joints. These joints allow bones to move in several directions. The joint at your elbow is a hinge joint. It can only move in two directions--back and forth. Your knees, toes, and fingers also have hinge joints.

1. Explain the function of ligaments.






2. Give an example of a pivotal joint and explain its action.
