To obtain the pattern for the database record, an individual inserts a finger into an attester terminal containing a near-infrared light-emitting diode (LED) light and a monochrome charge-coupled device (CCD) camera. The hemoglobin in the blood absorbs near-infrared LED light, which makes the vein system appear as a dark pattern of lines. The ...

Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...
Nearly forty years later in 1880, the piezoelectric effect was discovered and confirmed by Pierre and Jacques Curie. Both of these findings were used in the development of ultrasonography. The first ultrasound was applied to the human body for medical purposes by Dr. George Ludwig, University of Pennsylvania, in the late 1940s. [41] [42]

There are three sizes of veins: large, medium, and small. Smaller veins are called venules, and the smallest the post-capillary venules are microscopic that make up the veins of the microcirculation. [2] Veins are often closer to the skin than arteries. Veins have less smooth muscle and connective tissue and wider internal diameters than ...
Mean arterial pressure (MAP)is a weighted average of systolic and diastolic blood pressures, and is a better measurement of perfusion over the duration of the cardiac cycle. [16] Vasodilation works to decrease vascular resistance and blood pressure through relaxation of smooth muscle cells in the tunica media layer of large arteries and smaller ...
