Frontal lobes:, V They have motor area which controls voluntary motor activities or movements of, muscles,, V The premotor area is higher centre for involuntary movements and autonomus, nervous system., V Association area is for coordination between sensation and movements. Broca's, area/motor speech area., v It translates the thoughts into specch. Expression of enmotions, intelligence,, willpower, memory, personality areas are located in the frontal lobe.
