5giant a waves — abnormally tall a waves in tracings of the jugular venous pulse; they occur when either inflow resistance to or outflow resistance from the right ventricle is increased or when atrial contractions occur out of phase, during the period the… …
6Internal gravity waves — Gravity waves occur at interfaces between high and low density fluids. Most people are familiar with water surface waves, which act between water (as in lakes or oceans) and the air.Where low density water overlies high density water in the ocean …
7alpha waves — brain waves in the electroencephalogram which have a frequency of 8 to 13 per second; they are typical of the normal person awake and in a quiet resting state and occur principally in the occipital region …
8beta waves — brain waves in the electroencephalogram, which have a frequency of 18 to 30 per second; they are typical during periods of intense activity of the nervous system and occur principally in the parietal and frontal regions …
9theta waves — brain waves in the electroencephalogram which have a frequency of 4 to 7 per second; they occur mainly in children but also in adults during periods of emotional stress …
