- B.
Where two bones meet and move
- C.
The outer coating of the bone
- D.
The hard part of a skeleton
Correct Answer
B. Where two bones meet and moveExplanation
A joint is where two bones meet and move. Joints are responsible for allowing movement and flexibility in the body. They are found throughout the body and come in various types, such as hinge joints, ball-and-socket joints, and pivot joints. The cushion between two bones is actually called cartilage, which helps to reduce friction and absorb shock in the joint. The outer coating of the bone is known as the periosteum, and the hard part of a skeleton refers to the bones themselves.Rate this question:

Which two joints move the same way in our skeleton?
- A.
Knee joints and neck joints
- B.
Knee joints and elbow joints
- C.
Shoulder joints and elbow joints
- D.
Ankle joints and neck joints
Correct Answer
B. Knee joints and elbow jointsExplanation
The knee joints and elbow joints move in the same way in our skeleton. Both of these joints are hinge joints, which means they allow movement in only one plane, like a door hinge. They enable flexion and extension movements, allowing the limbs to bend and straighten. In contrast, shoulder joints are ball-and-socket joints, allowing a wider range of movements, and ankle joints are also hinge joints but have a different range of motion compared to knee joints and elbow joints. Neck joints, on the other hand, allow for rotation and tilting movements, which are different from the movements of knee and elbow joints.Rate this question:
