Destruction of the upper motor neurons in the left lateral pathway results in loss of

Right side's movement

Explanation:

The left lateral side of the brain is responsible for the movement of the right side

There is a primary motor cortex that is responsible for the movement of right side of the body. The sensation produced in right limb cross to the other side and causes movement of the left side or vice versa.  In such case destruction of the upper motor neurons in the left lateral pathway results in loss of Right side's movement

Movement on the right side

Explanation:

Motor neurons are a type of nerve cell that functions to send impulses from central nervous system cells to muscle cells or glands so that the body will respond to these stimuli by moving or producing secretory products. Motor nerve cells usually have short dendrites with very long axons.

On the left side, the left has control over the movements on the right side and vice versa.

So when there is destruction of the upper motor neurons in the left lateral path it will cause loss of movement on the right side.
