Which of the following objects is correctly matched with a type of joint that performs a similar movement?

Question

A cabinet which is similar to a pivotal joint
A doorknob, which is similar to a pivot joint
A swivel chair, which is similar to a hinge joint
A shower head,which is similar to a hinge joint

Answer 1

The object that is correctly matched with a type of joint that performs a similar movement is:

A doorknob, which is similar to a pivot joint.

In this case, the rotational movement of turning a doorknob resembles the movement at a pivot joint, where one bone rotates around another.

The other options involve misalignments with joint types and their respective movements. For example, a swivel chair operates more like a pivot joint than a hinge joint, and a shower head does not function like a hinge joint.
