| salt-losing nephritis | A rare disorder resulting from renal tubular damage of a variety of aetiologies; mimics adrenocortical insufficiency in that abnormal renal loss of sodium chloride occurs, accompanied by hyponatraemia, azotemia, acidosis, dehydration, and vascular collapse. Synonym: salt-losing syndrome, Thorn's syndrome. (05 Mar 2000) |

Beating or palpitation; as, the saltation of the great artery. 3. <biology> An abrupt and marked variation in the condition or appearance of a species; a sudden modification which may give rise to new races. "We greatly suspect that nature does make considerable jumps in the way of variation now and then, and that these saltations give rise to some of the gaps which appear to exist in the series of known forms."

| saltatory | Leaping or dancing; having the power of, or used in, leaping or dancing. <biology> Saltatory evolution, an affection in which pressure of the foot on a floor causes the patient to spring into the air, so as to make repeated involuntary motions of hopping and jumping.

| saltatory chorea | Rhythmic dancing movements, as in procursive chorea. (05 Mar 2000) |
| saltatory conduction | A method of neuronal transmission in vertebrate nerves, where only specialised nodes of Ranvier participate in excitation. This reduces the capacitance of the neuron, allowing much faster transmission. See: myelin, Schwann cells. (18 Nov 1997) |
