neurotaxis
1. A tendency of nerve cells to remain close to their sources of stimulation by migrating, both in the course of their development and evolution.
2. Theory that nerve cells tend to grow in the direction of most stimulations.
neutrotaxis
Stimulation of neutrophilic leukocytes by a substance in such a manner that they are either attracted, and move toward it or they are repelled, and move away from it.

In some instances, there is no effect, which is then referred to as indifferent neutrotaxis.

nomotaxia

organotaxis

2. A directed response of a motile organism to an organ.
orthotactic
The positional, constraints on the sequences of graphemes that are used in words.
osmotaxis
1. The movement of cells as affected by the density of the liquid containing them.
2. A directed response of a motile organism to osmotic pressure gradients.
oxygenotaxis (s) (noun), oxygenotaxes (pl)
A directed response of a motile organism towards or away from an oxygen stimulus; aerotaxis: The changes in the amount of oxygen concentration in air, for example, has an influence on bacterial movement, also termed oxygenotaxis, or on other organisms.
oxytaxis (s) (noun) (no pl)
A directed response of a motile organism to an oxygen stimulus: Tests have shown that marine larvae tend to avoid their habitat in low oxygen areas and orient themselves towards a supply of oxygen, and this reaction is termed oxytaxis.
parataxis, paratactic
1. The juxtaposition of clauses or phrases without the use of coordinating or subordinating conjunctions; as, "It was cold; the snows came."
2. The sequential ordering of proposition or clauses, without an indication of the relation (or co-ordination or subordination) between them by means of connecting words; the joining of sentences, phrases, or clauses without the use of conjunctive words; for example, "I came, I saw, I conquered." or "Drive carefully, the road is wet."

phobotactic (adjective); more phobotactic, most phobotactic
A fear of arrangement or order: Clarence never liked organizing things in perfect formation and sequence, but liked them to happen by using a phobotactic method, or by trial and error instead, especially when he was playing a game for the first time!
phobotaxis (s) (noun) (no plural)
In biology, an avoidance reaction of a motile organism: Phobotaxis is a response to a stimulus effectuating a cell or microbe to move in a random direction.
