(Greek: arrangement, order, put in order, orientation; the movements or directed responses of motile organisms to stimuli, as indicated by the combining roots)

telotaxis
Orientation or movement of an organism with sensory receptors in response to an external stimulus.
thermotactic (adjective)
1. A reference to the movement of an organism toward or away from a source of heat.
2. The regulation of the bodily temperature.
thermotaxis (s) (noun), thermotaxes (pl)
1. Reaction of living protoplasm to the stimulus of heat.
2. Normal regulation of body heat.
3. The thermo-regulatory function of the nervous system.
4. The movement or simulation in a living body exposed to heat.
5. The directed response of a motile organism towards (positive) or away from (negative) a heat stimulus.
6. The movement of a freely moving organism in response to heat.
thigmotaxis
1. Movement of an organism toward or away from any object that provides a mechanical stimulus or touch.
2. A directed response of a motile organism to a continuous contact with a solid surface.
3. Taxis, or movement, in response to touch stimulus.
tonotaxis
The orientation of osmotic pressure.
topochemotaxis
Directed movement or orientation of a motile organism towards the source of a chemical stimulus.
topogalvanotaxis
The directed movement or orientation of a motile organism towards the source of an electric stimulus.
topophototaxis
The directed movement or orientation of a motile organism towards the source of a light stimulus.
topotaxis
The directed movement or orientation of a motile organism towards the spatial gradients of a stimulus; especially, the source of a stimulus.
traumatotaxis (s), traumatotaxes (pl) (nouns)
1. Movement of motile organisms, cells, or organelles (intracellular structures) in response to injury.
2. Reaction after wounding, as in nuclei and protoplasts (living content of a plant cell).
trichotaxis
The order or arrangement of hair.
trichotaxy, trichotactics
Arranging or putting hair in some kind of order.
trophotaxis
Chemotaxis of an organism in response to nutritive material.
tropotaxis
1. The movement of an organism toward or away from a stimulus as a result of comparing sensory input received from paired receptors on both sides of the body.
2. The movement or orientation of an organism in response to two stimuli, especially lights, by means of different sense organs.
3. The movement or orientation of an organism in response to the difference in stimulation of two symmetrically placed receptors.
vibrotaxis
1. Orientation to vibration; vibrokinesis.
2. The detection of associated movement.
3. An organism's response to mechanical vibrations.
