In addition to movement, what is the other function of the skeletal
system?

The other function is for "protection." The skeletal system protects the body's internal organs.

Explanation:

The "skeletal system" refers to the "skeleton" or the framework of bones of the human body, including the joints. It has several functions. One of these is to protect the body's internal organs. It prevents these organs from getting injured. For example, the skull protects the brain (which is very delicate) while the thorax protects the viscera organs such as the lungs and heart.

Besides this, the skeletal system also functions for support, movement, storage of important minerals, production of red blood cells and white blood cells, etc.
