Question

Match the following and choose the correct option
$\begin{array}{cc}\text{Types of synovial~joints}& \text{Bones involved}\\ \text{A. Ball and socket}& \text{1. Carpal and metacarpal of thumb}\\ \text{B. Hinge}& \text{2. Atlas and axis}\\ \text{C. Pivot}& \text{3. Frontal \& Parietal}\\ \text{D. Saddle}& \text{4. Knee}\\ & \text{5. Humerus and pectoral girdle}\end{array}$

• A. A = 1, B = 3, C = 4, D = 5
• B. A = 5, B = 4, C = 2, D = 1
• C. A = 5, B = 4, C = 3, D = 1
• D. A = 1, B = 2, C = 5, D = 4

Answer 1

The correct option is B

A = 5, B = 4, C = 2, D = 1

A synovial joint is a connection between two bones consisting of a cartilage lined cavity filled with fluid, which is known as a diarthrosis joint. These joints help in locomotion and many other movements. Ball and socket joint (between humerus and pectoral girdle), Hinge joint (knee joint), Pivot joint (between atlas and axis), Gliding joint (between the carpals) and Saddle joint (between carpal and metacarpal of thumb) are some examples.
