The correct answer is the right side.
The brain is divided into two hemspheres: the right and the left. Each hemisphere controls the opposite side of the body, so if the left arm is paralized, the right side of the brain is injured. Hemispheres have different functions, meaning that they control different activities and skills.
Answer:
The correct answer is the motor cortex association.
Explanation:
The motor cortex refers to a component of telencephalon that in turn is the component of the brain. Its prime activity is to encourage movement. With the help of this one can produce, sustain, and complete the movements.
With the help of the motor cortex, one can produce voluntary movements deliberately. This part of the brain is situated in the frontal lobe, just in the anterior part of the somatosensory region and Rolando's fissure.
If the section of the brain, where the motor cortex is present get injured, then the movement of certain parts of the body may get restricted or may even get lost. Due to this, if Marta lost her movements of the arm after suffering a brain injury due to an accident, it can be concluded that the accident incapacitated the motor cortex region.
