Question

The bones at the elbow are joined by a ___ joint.

• A. pivot
• B. hinge
• C. gliding
• D. ball and sockets

Answer 1

The correct option is B

hinge

Hinge joints are joints like door hinge where only back and forth movement is possible. These are found in fingers and toes, knee, elbow, etc. Pivot joints consist of the rounded end of one bone fitting into a ring formed by the other bone. Ball and socket joints possess a rounded, ball-like end of one bone fitting into a cuplike socket of another bone. Examples of ball-and-socket joints are the shoulder and hip joints. Gliding joints occur between the surfaces of two flat bones that are held together by ligaments. Some of the bones in the wrists and ankles move by gliding against each other.
