There is something called the Homunculus that illustrates which parts of the motor cortex control which region. It ends up looking like a C with the leg being the smallest part and the face especially the tongue being the largest.

Motor cortex is a region found in the cerebral cortex of the brain. It main function is to plan, control, and execute voluntary motor processes.

Motor functions are controlled in the motor cortex (particularly, the primary motor cortex and premotor cortex), which are substantially located in the parietal lobe (roughly the rear third of the top of the brain).
I have no idea but I need to now for my science project
The motor cortex is found in the brain.
Motor neurons are nerve cells that are located in the motor region of the cerebral cortex or brain stem.
Probably the best-known region of the brain associated with motor control (movement) is the primary motor cortex. The primary motor cortex is located in the precentral gyrus, just anterior to the central sulcus.However, the pre-motor areas of the frontal lobe, as well as the cerebellum are also very involved with motor control.
The somatic motor cortex is located in the human brain. It can be found in the posterior portion of the frontal lobe.

Pre central gyrus has got the motor cortex. Through this area you get the initiation of final motor pathway.
