(Greek: arrangement, order, put in order, orientation; the movements or directed responses of motile organisms to stimuli, as indicated by the combining roots)
acroataxia
Ataxia affecting the distal portion of the extremities; such as, hands and fingers, feet, and toes.
Ataxia is the inability to coordinate muscle activity during voluntary movement, so that smooth movements occur.
adelphotaxis, adelphotaxy
1. The tendency of motile cells to assume a particular arrangement, usually a mutual relationship.
2. The mutual attraction between spores after extrusion.
aerotaxis, aerotactic
1. A movement of an organism in response to the presence of molecular oxygen.
2. The directed movement of a motile organism towards (positive) or away from (negative) an air-liquid interface, or a concentration gradient of dissolved oxygen.
allelotaxis, allelotaxy
1. The formation, during development, of one organ from more than one embryologic structure.
2. Development of a part from several embryonic structures or tissues.
amyotaxia, amyotaxy
Muscular incoordination attributable to cerebellar lesions; ataxia.
anemotaxis
An orientation or movement of a free-living organism in response to wind or air currents.
angioataxia
An irregular tension of the blood vessels.
angiostaxis
1. An obsolete term for the oozing of blood; bleeding.
2. The oozing of blood, as seen in hemophilia.
anthesmotaxis
The organization and arrangement of the various parts of a flower.
anthotaxia, anthotaxy
1. The arrangement or disposition of flowers in a cluster.
2. The science of the relative position of flowers; inflorescence.
aphototaxis, aphototactic
The absence of any directed response to a light stimulus in a motile organism; negative phototaxis.
aphydrotaxis, aphydrotactic
1. The absence of a directed response of a motile organism to water.
2. The directed reaction of a motile organism away from moisture.
apothermotaxis
The absence of a directed response of a motile organism to a thermal (heat) stimulus.
argotaxis, argotactic
Passive movement due to surface tension.
asyntaxia
Lack of proper and orderly embryonic development.
