Document Summary

Parietal lobe - one of four cerebral lobes; located just posterior to the central fissure. The posterior parietal association cortex plays a role in knowing the positions of various body parts and of objects in the external world. Posterior parietal association cortex an area of association cortex that receives input from the visual, auditory, and somatosensory systems and is involved in the perception of spatial location and guidance of voluntary behavior. Left parietal lobe - is specialized for operation of limbs, hands, and eyes within immediate interpersonal space. Basal ganglia -collection of subcortical nuclei (the caudate, putamen, globus pallidus, and amygdala) that have important motor functions, including the modulation and coordination of motor activity. Cerebellum - the metencephalic structure located just dorsal of the pons. modulates balance and adjustments in posture. Brainstem - part of the brain on which the cerebral hemispheres rest; regulates reflex activities that are critical for survival (heart rate and respiration.
