Cardiac glycoside specifically categorized based on the plant they are derived from, as in the following list. For example, cardenolides have been primarily derived from the foxglove plants "Digitalis purpurea" and "Digitalis lanata", while bufadienolides have been derived from the venom of the cane toad "Bufo marinus", from which they receive the “bufo” portion of their name. Below is a full list of plants from which cardiac glycosides can be derived. Cardiac glycosides affect the sodium-potassium ATPase pump in cardiac muscle cells to alter their function. Normally, these sodium-potassium pumps move potassium ions in and sodium ions out. Cardiac glycosides, however, inhibit
Where Mathematics Comes From Where Mathematics Comes From Where Mathematics Comes From: How the Embodied Mind Brings Mathematics into Being (hereinafter "WMCF") is a book by George Lakoff, a cognitive linguist, and Rafael E. Núñez, a psychologist. Published in 2000, "WMCF" seeks to found a cognitive science of mathematics, a theory of embodied mathematics based on conceptual metaphor. Mathematics makes up that part of the human conceptual system that is special in the following way: Nikolay Lobachevsky said "There is no branch of mathematics, however abstract, which may not some day be applied to phenomena of the real world." A common type of conceptual
