AP PSYCHOLOGY

Detailed explanation-1: -When you want to lift your fork, wave your hand, brush your hair or wink at a cutie, you form the thought and then an area in the cerebellum translates your will into action. The largest of the three brain sections, accounts for about 85 percent of the brain’s weight, and has four lobes.

Detailed explanation-2: -Frontal Lobes These include motor skills such as voluntary movement, speech, intellectual and behavioral functions. The areas that produce movement in parts of the body are found in the primary motor cortex or precentral gyrus.

Detailed explanation-3: -The Cerebellum This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.

Detailed explanation-4: -Collectively, your cerebral cortex is responsible for the higher-level processes of the human brain, including language, memory, reasoning, thought, learning, decision-making, emotion, intelligence and personality.

Detailed explanation-5: -What part of the brain modifies the activity of upper motor neurons to produce voluntary movements and inhibit involuntary ones? Dopamine binds receptors in the cerebral cortex to activate upper motor neurons to produce coordinated and smooth movements.
