Document Summary

Cerebrum: neural network with 2 large hemispheres that contribute to 85% of brains weight, enables perceiving, thinking, speaking. Cerebral cortex: intricate fabric of interconnected neural cells covering central hemispheres, body"s ulimate control and informaion processing center. Larger cortex: higher capacity for learning and thinking, more adaptable. Glial cells: supports, nourishes, and protects neurons, worker bees , provides nutrients and insulaing myelin, guides neural connecions, mops up ions and neurotransmiters, informaion transmission, memory. Frontal lobe: lies just behind forehead, speaking, muscle, movement, making plans, judgement. Parietal lobe: lies at top near the rear, sensory input and receiver for touch and body posiion. Occipital lobe: lies at back of head, receives info from visual ields. Temporal lobes: above ears, includes auditory and receives informaion from opposite ear. Motor cortex: area at rear of frontal lobe, controls voluntary movement. Sensory cortex: area at front of parietal lobe, registers and processes body touch and movement sensaions.
