Question

How would your hand function differently if your thumb contained a pivot joint? What if it contained a ball and socket joint?

Answer 1

Answer:

The saddle joint that can be found in the thumbs ensures that it moves from side to side and rotate on its own axis alone.

The saddle joint allows movement in different directions but only a small amount of rotation. The thumb is the only organ that has a saddle joint.

It should be noted that the bones that are in the saddle joint ensure the back and forth movement of the thumbs.

The pivot joint is the joint that's responsible for ensuring that one bone rotates around another bone. Ball and socket joint can be found in the shoulder and the hip and it allows for greater freedom of movement.

When compared to other movable joints, the saddle joint is prone to dislocation because it's free-moving and rotates on its own axis alone.

In conclusion, if the thumb contained a pivot joint or a ball and socket joint, it'll be able to move more freely.



 I hope this helps! :)

Answer 2

Answer:

Explanation:

if the thumb had a pivot point joint, the thumb will not be as flexible and only be able to movie in a rotary motion.

A ball and socket joint will help movement in all directions and has a greater range of movement when in comparison to other joints.
