The major motor pathway that controls (the majority of) our muscles is called the Corticospinal Tract. This set of neurons starts (has its cell bodies/dendrites) in the Primary Motor Cortex (M1), and projects (sends axons) down through the brain and into the spinal cord, allowing us to move.
The neurons that control the left side of our body do indeed begin on the right side of our brain in the M1 area. The axons of these neurons stay on that side of the brain through the internal capsule, through the cerebral penduncle (in the midbrain), and to the medullary pyramid (in the medulla).
At this point, the axons decussate - cross over from one side to the other - and continue down the corticospinal tract in the spinal cord, where they eventually synapse to other neurons that leave the spinal cord and affect our muscles. It is this decussation in the medullary pyramid that leads to one side of our brain controlling the other side of our body.
Since axon decussation has evolved in many distinct systems and organisms, it seems reasonable to presume that decussation confers a significant functional advantage - yet if this is so, the exact nature of this advantage is not clearly understood.
Current research seems to indicate that in order to reduce connection errors in a complex computing network such as the human brain and CNS, with its 3-dimensional somatotropy, axonal decussation across the midline and corticospinal tract would be necessary.
The brain is responsible for coordinating all body activities. It receives and processes information from the senses, sends out signals to different parts of the body, and controls functions such as movement, thinking, and breathing.
The communication network that controls and coordinates most body activities is called the nervous system. It is a complex network of specialized cells called neurons that transmit signals between different parts of the body, allowing for rapid communication and coordination of various physiological processes.
The brain.
Your right brain is on the right side of your head. However, the motor cortex (or motor strip) controls movements on the left side of your body. The right brain is more involved in spatial activities, overall, whereas the left brain has more involvement with speech and language (Broca's and Wernicke's areas).
The cerebral cortex, specifically the prefrontal cortex, plays a significant role in controlling conscious activities of the body. This region is responsible for executive functions such as decision-making, planning, and voluntary movements.

The primary motor cortex, located in the frontal lobe of the brain, is responsible for controlling and directing motor activities in the body. It sends signals to the muscles to initiate movement and coordinates the execution of voluntary movements.
