Biology Prefixes and Suffixes: -kinesis, -kinesia

Cancer Cell Mitosis

Suffix -kinesis


The suffix (-kinesis) refers to undirected movement, motion, or activation that may be caused by a stimulus. The word or suffix kinesia refers to a motion-related sickness or disorder.


Angiokinesis (angio-kinesis) - refers to the movement of a blood vessel.

Chemokinesis (chemo-kinesis) - activity or stimulation of a cell or organism as the result of the presence of a chemical substance.

Diakinesis (dia-kinesis) - the last of five stages in Prophase I of meiosis. In this stage, chromosomes shorten, the nuclear membrane disappears and the spindle fibers form.

Electrokinesis (electro-kinesis) - behavior exhibited in microbes, such as bacteria, that involves the consumption of electrochemical energy from metal surfaces in order to produce certain movements.

Cytokinesis (cyto-kinesis) - the process of dividing the cytoplasm of a cell in order to form two distinct daughter cells. This cell-splitting happens at the end of mitosis and meiosis. In meiosis however, four daughter cells are produced after two division processes.

Karyokinesis (karyo-kinesis) - the division of the nucleus that occurs in the mitosis and meiosis stages of the cell cycle.

Lymphokinesis (lympho-kinesis) - refers to the movement of lymph as it travels through lymphatic vessels in the lymphatic system.

Parakinesis (para-kinesis) - motor function disorder that results in abnormal movements.

Photokinesis (photo-kinesis) - the movement or response of a cell or organism to a light stimulus.

Psychokinesis (psycho-kinesis) - refers to uncontrolled, impulsive behavior. It also refers to the supposed ability to move objects with only the mind.

Telekinesis (tele-kinesis) - the movement of an object without any physical contact.

Thrombokinesis (thrombo-kinesis) - refers to blood coagulation. Thrombocytes, also called platelets, are blood cells that are responsible for blood clotting.

Suffix -kinesia

Akinesia (a-kinesia) - loss of voluntary motor function or temporary paralysis of muscles. It also means without movement.

Acrokinesia (acro-kinesia) - excessive movement of the limbs.

Bradykinesia (brady-kinesia) - exhibiting abnormally slow movement. This condition is often exhibited by individuals with nervous system disorders such as Parkinson's disease.

Dysdiadochokinesia (dys-diadocho-kinesia) - the inability to perform movements that exhibit a wide range of motion, typically caused by disorders of the cerebrum.

Dyskinesia (dys-kinesia) - family of disorders that result in impairment of voluntary movement.

Echokinesia (echo-kinesia) - behavioral disorder that involves imitating the movements of others. It is also called echopraxia.

Hyperkinesia (hyper-kinesia) - excessive movement caused by increased activity of muscle tissue.
