Question

why is it that we are able to move a few parts of our body easily in various directions and some only in one direction?​

Answer 1

Answer:

We can bend or move our body parts only at those places where two bones join together. Such places are called joints. The amount of movement depends on the type of joint, e.g. Ball and socket joint allows movement in all directions whereas hinge joint allows only one directional movement.
