CH2 Central Nervous system •white matter (inner structure) made of myelin-covered axons "myelinated axons" •grey matter (outer layer)made cell bodies & dendrites of neurons Frontal lobe: thinking,coordinate movement Parietal lobe: pain,temperature(sensory cortex) Occipital lobe:sensation from eyes, images, stored in memory Temporal lobe:smell, taste, sound 1. sensory (somatosensory) cortex :receives stimuli from ascending pathway •Sensory (ascending) pathway: Signals from the neurons with general senses (touch, pressure, temperature and pain) 2. CNS interprets: integrates sensory information 3.Motor cortex: sends messages via motor neurons to skeletal muscles (target effectors)
