Motility

Motility ( lat. Motio "movement") describes the ability to actively move. On the other hand, the property of being able to move is called mobility (passive mobility). The opposite word is sessility .

Importance in biology and medicine

In biology and medicine , the term motility is more narrowly defined and is restricted to involuntary movement processes in the body (e.g. movements of the intestine ; see peristalsis ). An excessive movement activity is called hypermotility , a decreased activity is called hypomotility .

• Especially in ophthalmology , motility is the ability to move the eyes .
• In a broader sense, the term is also used to describe the mobility of the skeletal muscles .
• In diseases of the nervous system , a distinction is made between increased ( hyperkinesis ), decreased ( hypokinesis ) or lack of motility ( akinesia ).

Cell biology: cell motility

Cell motility is an amoeboid movement of the entire cell (as in leukocytes ) or a flow and stream in the protoplasm of the cell.

The motility of the sperm is an important criterion for the quality of the sperm in artificial insemination or artificial insemination .

Social Sciences: Human Motility

The term is used by Vincent Kaufmann , Max Bergman and Dominique Joye in sociology . It describes the ability of people to move, which is unevenly distributed among the population. Usually this is treated as "Horizontal Mobility ". Canzler et al. define motility as the capacity or competence of an actor to move socially and spatially.
