Question

1. Synovial joints can be classified based on the shape of the bone ends that make up the joints. For example, a  ____________  joint consists of two flat (or nearly flat) bone ends that can slide over each other.
2. Joints classified as  ____________  joints have one cylindrical bone end that articulates with a ring made up of another bone and a ligament.
3. Joints consisting of the head of one bone fitting into a cup-shaped depression on the other bone are called  ____________  joints.
4. If one bone end within a joint is convex and the other is concave, the joint is called a  ____________  joint. If both bone ends each have convex and concave regions, the joint is a  ____________  joint.
5. Joints with one oval-shaped rounded bone end that articulates with an elliptical cavity on another bone end are classified as  ____________  joints.

Answer 1

Answer

1. Synovial joints can be classified based on the shape of the bone ends that make up the joints. For example, a plane joint consists of two flat (or nearly flat) bone ends that can slide over each other.
   
   
2. Joints classified as pivot joints have one cylindrical bone end that articulates with a ring made up of another bone and a ligament.
   
   
3. Joints consisting of the head of one bone fitting into a cup-shaped depression on the other bone are called ball and socket joints.
   
   
4. If one bone end within a joint is convex and the other is concave, the joint is called a hinge joint. If both bone ends each have convex and concave regions, the joint is a  saddle joint.
   
   
5. Joints with one oval-shaped rounded bone end that articulates with an elliptical cavity on another bone end are classified as condyloid joints.
