is only area-4 of the brain can initiate fine movements
1 answer
No, area-4 (also known as the primary motor cortex) is responsible for the initiation of voluntary movements, including fine movements. However, it does not solely control all fine movements in the body. Other areas of the brain, such as the supplementary motor area and the premotor cortex, also contribute to the planning and execution of fine motor skills. Additionally, other regions of the brain, such as the cerebellum and the basal ganglia, play important roles in coordinating and refining fine movements.
