Document Summary
Corticobulbar tracts: run from cortex to pons and medulla, and control facial movement. Corticospinal tracts: run from cortex to the spinal cord, and control movement of the trunk and periphery. Controls movement in peripheral areas (hands and feet) Allows control of muscles of the neck, shoulders and trunk. Enables movements such as walking, turning, bending, standing up, and sitting down. Broca"s area (area 45/44) and the supplementary area (dorsal area 6) Ask patient which two things appear twice (requires fine control of eye. Involves response inhibition. need to look at the opposite side of where the stimulus occurs. Relates to the stability of the world as the individual moves. There is a voluntary component to our actions, neural signals prepare for the perception of a stable world if movement is going to take place. The frontal lobe signals the parietal and temporal cortex neurons. This informs the sensory system for anticipated changes.
