Laws of Physiology
Irene Gold Laws of physiology
Law | Name of Law |
---|---|
Anterior roots are motor, Posterior spinal roots are sensory | Bell Magende |
at constant temperature, gas volume is inversely proportional to pressure | Boyle's Law |
at constant pressure, gas volume is proportional to absolute temperature | Charles' Law |
minimum interval of time necessary to electrically stimulate a muscle or nerve fiber using twice the minimum current to elicit threshold response | Chronaxie |
membrane potential on the inside of a membrane when 2 univalent positive ions, Na+ and K+ and one univalent negative ion, chloride, are involved | Goldman |
gas solubility in a liquid is proportional to gas pressure | Henri's Law |
limits respiratory excursion via Vagus nerve | Hering Breuer |
The tension in an artery will be proportional to the radius of the vessel | La Place's Law for ARTERIES |
The ventricular pressure depends on muscular tension, size, and shape of the heart | La Place's Law for the HEART |
Potential level across a membrane exactly opposes net diffusion of particles through the membrane | Nernst |
minimum electrical current of infinite duration to elicit a threshold response | Rheobase |
cardiac output is equal to venous return | Frank-Starling's Law |
Peripheral resistance is directly proportional to the viscosity of blood and to the length of the vessel and inversely proportional to the radius of the vessel to the 4th power | Poiseuille's law |
