  • noun Protoplasm or cytoplasm.
  • noun The fluid portion of milk from which the curd has been separated by coagulation; whey.
  • noun Physics An electrically neutral, highly ionized phase of matter composed of ions, electrons, and neutral particles. It is distinct from solids, liquids, and gases.
  • adjective Of or relating to a flat-panel display used in televisions, made up of an array of tiny cells each containing a gaseous mixture of xenon and neon that is changed into a plasma state to illuminate a phosphor coating on the inside of the cell.

from The Century Dictionary.

  • noun A variety of translucent quartz, or silica, of a rich grass-green or leek-green color, occurring in large pieces, associated with common chalcedony. Many fine engraved ornaments of this stone have been found among the ruins of Rome.
  • noun The liquid part of unaltered blood, lymph, or milk, as distinguished from the corpuscles of the blood or lymph, or the oil-globules of the milk; also, the juice expressed from fresh muscle; the muscle-plasma
  • noun The primitive indifferent nitrogenized hydrocarbon which forms the basis of all tissues of plants and animals; the “physical basis of life,” in its simplest expression: now generally called protoplasm.
  • noun In pharmacy, same as glycerite of starch.

  • noun (Min.) A variety of quartz, of a color between grass green and leek green, which is found associated with common chalcedony. It was much esteemed by the ancients for making engraved ornaments.
  • noun (Biol.) The viscous material of an animal or vegetable cell, out of which the various tissues are formed by a process of differentiation; protoplasm.
  • noun Unorganized material; elementary matter.
  • noun (Med.) A mixture of starch and glycerin, used as a substitute for ointments.
  • noun same as blood plasma.
  • noun (physics) a state of matter in which charged particles such as electrons and atomi nuclei have sufficiently high energy to move freely, rather than be bound in atoms as in ordinary matter; it has some of the properties of a gas, but is a conductor of electricity.
  • noun (Physiol.) the colorless fluid of the blood, in which the red and white blood corpuscles are suspended. It may be obtained by centrifuation of blood to remove the blood cells. It is distinguished from serum in that plasma still has the fibrin of blood, and may be clotted, while in serum the fibrin has been removed.
  • noun (Physiol.) the fundamental part of muscle fibers, a thick, viscid, albuminous fluid contained within the sarcolemma, which on the death of the muscle coagulates to a semisolid mass.
