Question

Which two joints move the same way in our skeleton?

• A. Knee joints and the neck
• B. Knee joints and elbow joints
• C. Shoulder joints and the elbow joint
• D. Ankle joints and the neck joints
  

Answer 1

The correct option is B Knee joints and elbow joints

A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend.
An example of a pivot joint in the human skeletal system is the rotation of the atlas around the axis.
The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket.
