What's the difference between auriculated and bivalve?

Auriculated


Definition:

  • (a.) Having ears or appendages like ears; eared. Esp.: (a) (Bot.) Having lobes or appendages like the ear; shaped like the ear; auricled. (b) (Zool.) Having an angular projection on one or both sides, as in certain bivalve shells, the foot of some gastropods, etc.

Example Sentences:

  • (4) The following criteria of the myocardial insufficiency were revealed on myocardial fragments of the human auricule tissue (auricula atrii) removed in correction of the valvular cardiac defects: 1) fall of the contraction amplitude in the rhythmic row even with the stimulation frequency of 1--3 Hz (normal mycadrium is characterized by increased contraction amplitude--positive Bowdwitch steps) 2) monophasic character of the frequency-force curve (in a normal myocardium the curve is three-phasic in shape); 3) the absence of positive or the appearance of negative inotropic effect in response to reduction of the external Na concentration or removal of K ions from the solution.

Bivalve


Definition:

  • (n.) A mollusk having a shell consisting of two lateral plates or valves joined together by an elastic ligament at the hinge, which is usually strengthened by prominences called teeth. The shell is closed by the contraction of two transverse muscles attached to the inner surface, as in the clam, -- or by one, as in the oyster. See Mollusca.
  • (n.) A pericarp in which the seed case opens or splits into two parts or valves.
  • (a.) Having two shells or valves which open and shut, as the oyster and certain seed vessels.

  • (6) Attempts to introduce infectious or foreign material into oysters and other bivalve mollusks usually involve force or trauma because of immediate, prolonged adduction of the tightly closing valves.
  • (7) This observation, together with the finding that the oyster shell has a strong affinity for virus, suggests that surface properties, rather than size, are the principal factors governing the accumulation of viruses by filter-feeding marine bivalves.
