What's the difference between confluence and convergence?

Confluence


Definition:

  • (n.) The act of flowing together; the meeting or junction of two or more streams; the place of meeting.
  • (n.) Any running together of separate streams or currents; the act of meeting and crowding in a place; hence, a crowd; a concourse; an assemblage.

  • (15) The total number of lesions varied, though not greatly, over the whole follow-up, but there was an influence of the clinical course of MS on the pattern of lesions in MR imaging, mostly in respect to the number of confluences and the size of the lesions.
  • (16) 3) The pressures of the inferior vena cava at the confluence of right and left common iliac veins with 20 and 40mmHg showed no significant difference immediately after the pressurization, but thereafter showed a increasing tendency in the group with 40mmHg (p less than 0.05).

  • (19) After the preselection of patients based on knowledge of the anatomical patterns, a systemic-pulmonary artery shunt may be performed without cardiac catheterization if these rules for definitive patient selection are followed: (1) accurate clinical assessment to identify the patients with restricted pulmonary blood flow; (2) precise intracardiac diagnosis by 2-D and Doppler echocardiography; and (3) definitive 2-D echocardiographic visualization of the pulmonary venous connection and the confluence of the pulmonary arteries.
  • (20) Novel transformed variants generally arise after prolonged confluence and cessation of net growth, with these new types of foci appearing during a second round of confluence, although not in the first round.

Convergence


Definition:

  • (n.) Alt. of Convergency

Example Sentences:

  • (1) The ophthalmic headache's crisis is caused, in fact, by a spasm of convergence on an unknown exophory of which the amplitude of fusion is satisfying, and the presence of which can only be seen with test under screen.
  • (2) Since only a few of these medium sized terminals in any one cluster degenerate after tectal lesions, and none degenerate after cortical lesions, it is suggested that the morphological arrangement of these clusters may permit the convergence of axons from several sources, some of which are unidentified, onto the same dendritic segment.
  • (3) Eye movements of convergence and divergence were recorded by a limbus tracker.
  • (4) The silver impregnated axons of these cells converge to a paired centrosuperficial tract forming terminal enlargements at the ventrolateral surface of the spinal cord.
  • (5) The aim was to find out to what extent information from homonymous muscles of the forelimbs converge on the same CBM neurons and whether the probability of such a convergence depends on location (axial, proximal, distal) or function (flexor, extensor) of the tested muscles.
