allo-, all-

1. Passive or involuntary movement; drifting: The elderly Mr. Brown suffered from allokinesia and had problems eating at the table because of couldn't control his muscle movenents.

Allokinesia involves the involuntary copying in one limb of a voluntary movement in the opposite limb.

1. Pertaining to something that moves passively: Plankton, for example, are allokinetic and drift in moving ocean water, the external stimulus.
2. Regarding something that moves in a passive or reflexive manner: Lightweight debris that is high in the water can be allokinetic and are affected by wind drift or windage.

A speech defect that results from a disorder of the speech center: Susan was diagnosed by Dr. Kilfoil as having allolalia, which resulted from a cerebral injury.

Allolalia is a type of dysphasia in which words are spoken unintentionally, or inappropriate words are substituted for appro0priate ones.

A behavior pattern in which an animal applies some scent-marking substance to another of its own species: Allomarking has a number of functions, one of which can be a way of communication.

Pertaining to an allomother: In hthe hospital,allomaternal care was given to the baby girl until the real mother recovered from her operation.

In crystallography, an allomeric compound: An allomer is part of the crystalline structure of matter of dissimilar chemical composition

The co-ordinated activity of the lower brain stem and spinal cord: Allomeric function is considered to be the activeness of the lower section of the brain and the medulla spinalis when considered as a single performing unit.

Substances with a different chemical composition but the same crystalline form: Consistence in crystalline shape accompanied by variation in chemical composition is termed allomerism.

A reference to an organism which differs in the number of the parts of any organ from that which is customary in the group to which they belong: Jane read about allomeristic animals that had just one kidney instead of two like the other animals of its kind.

To go through allomerization: Joan learned that to allomerize was to mutually converst the allomeric shapess or forms.

fering in growth rate: Allometric growth is the development of different parts of the body of a living organism at different rates or at different times.

In humans, for example, allometric growth can be seen in brain growth that stops at about the age of five years, while other parts Difof the body continue to develop.

The study of relative growth: Allometry includes the investigation of the changes of proportions with an increase of size.

Allometry also consists of growth rates of a part differing from a standard growth rate or from the growth rate of the whole.

In addition, allometry involves the variations in the relative size of a part, either in the course of an organism's growth or within a series of related organisms, or the measurement and study of such variations.

Asexual development of an embryo or seeds: Sometimes allomixis can imply the substitution of the seed by a young or little plant or by a small bulb-like structure.

A chemical substance produced and released by one species in order to communicate with another species: Allomone is produced by an organism which induces in a member of another species a behavioral or physiological reaction favorable to the emitter and may be mutualistic or antagonistic.

1. Any of two or more different forms of the same chemical compound: One of various crystalline forms of a substance is termed an allomorph
2. In linguistics, one of the alternate contextually determined phonological shapes of a morpheme: An example can be "en" in "oxen", which is an allomorph of the English plural morpheme.
