Document Summary

Last major organ system to be understood. Alzheimer"s disease: 4 million americans, 14 million americans projected by middle of the century. Phrenology (19th century: feel the head for contours. Brain imaging (21st century: electrodes on specific sections of the brain, ethical issues. Nervous system extends to and controls all body. Somatic nervous system: sensory and motor. Diffuse enteric nervous system: digestive tract. Cns - brain spinal cord cauda equina. Sagittal - parallel from front to back: mid-sagittal - divide into left and right hemisphere. Subcortical nuclei: limbic system, basal ganglia. Frontal lobe: motor, cognitive function, higher intellectual capacity, precentral gyrus - primary motor cortex. Parietal lobe: sensory, postcentral gyrus - primary sensory cortex. Temporal lobe: auditory function, temporal sulcus/sylvian fissure. Corpus callosum: connects left and right hemisphere. Pons: bridge - goes around the brainstem. Cerebrospinal fluid (csf: transported through ventricles, produced in lateral ventricles, third ventricle located at thalamus, fourth ventricle at spinal cord. Basal ganglia: motor system, parkinson""s disease.
