difference between pivot joint and hinge joints
Answers
Explanation:
Like a door hinge, a hinge joint allows backward and forward movement. The pivot joint only allows rotating movement. An example of a pivot joint is the joint between the radius and ulna that allows you to turn the palm of your hand up and down
Explanation:
Pivot Joint:
Pivot joint, also called rotary joint, or trochoid joint, in vertebrate anatomy, a freely moveable joint (diarthrosis) that allows only rotary movement around a single axis. The moving bone rotates within a ring that is formed from a second bone and adjoining ligament
Hinge Joints:
A hinge joint (ginglymus) is a bone joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane. According to one classification system they are said to be uniaxial (having one degree of freedom).
Difference:
- >>Hinge joint is a joint between 2 bones such that it allows movement along one axis only. It is found n ankles, elbow and knees, and it also resembles a door with hinges in many aspects.
>>A pivot joint is a joint between two bones such that the convex surface of one bone is parallel to the axis of the other such that it provides free movement. It is found in the hip, shoulder and neck. It resembles a ball in a socket in many aspects.
- >>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.
