ser·vo·mech·a·nism

(ser'vō-mek'ă-nizm),
1. A control system using negative feedback to operate another system.
2. A process that behaves as a self-regulatory device; for example, the reaction of the pupil to light.
[L. servus, servant, + G. mēchanē, contrivance]

servomechanism

[sur′vōmek′əniz′əm]
a control system in which feedback is used to correct errors in another system. A biological example is the mechanism that controls the size of the pupil of the eye as the intensity of light changes.

servomechanism

(sŭr″vō-mĕk′ă-nĭzm)
In biology and physiology, a self-regulatory control mechanism that operates by negative feedback. For example, when the blood glucose level rises in the normal person, the pancreas responds by releasing insulin, which enables cells to take in and metabolize glucose. The level of other hormones is also regulated by this mechanism.

servomechanism

a control system that uses negative feedback (see FEEDBACK MECHANISM to maintain a level of output or performance.
