Document Summary

Connection between central system and muscles and nerves. Heart rate blood pressure and respiration (pump oxygen to muscles) Cold feet and hands (blood flows to central parts of body) Suppression of immune system, response to pain, and fertility. Communication between peripheral nervous system and brain. When there is an injury to the spinal cord, Loss of sensations for touch and pain. Magnet (its basically a really big strong magnet) All the hydrogen molecules in your body align with the magnetic force. Resonance: the pulse will bring them out of alignment. Stop pulse: the molecules will go back into alignment. Imaging: different molecules take a different amount of time to go back into alignment (eg. water 4000ms, cell bodies 920ms, axons 100ms) Visualizing the fiber bundles (axons, white matter) Diff activities that you do demand diff amount of activity brain does fmri- functional magnetic resonance imaging. Active brain regions need oxygen, which is delivered by blood.
