Skeleton – Movement and Locomotion – Notes
Body Movement – Joints and Their Types
Bones are joined together at places called joints and help in body movements.
Different animals use to different body parts for movement.
Each body part is capable of different movement, and is hence controlled by different types of joints.
Ball and socket joints allow flexible movement in all directions.
Ball and socket joints connect the arms to the shoulder and the legs to the hip.
The head is connected to the neck through the pivotal joint.
The pivotal joint contains a cylindrical bone that rotates in a ring.
The hinge joint at the elbow and the knee allows them to move back and forth.
Fixed joints make the bones immovable.
