 The mechanism of postural control As we all know muscles of the body play a major role in attaining both dynamic and static postures but, there is a contribution of some other body systems working simultaneously in co-ordination with the muscles. There is a center governing the simultaneously working systems of the body. Let us discuss all the important elements of postural control and their mechanism. 1.             The governing system of nervous control: The maintenance and adaptation of a posture is controlled by the system of nervous control. The system works on a give and take mechanism of receptor organs (eyes, ears, muscles and joints) giving the afferent stimuli and effector organs (muscles) receiving the command to perform the actions. All that is required for a brain to change a position is an input to produce an output. The input can either be environmental (push, pull, jerk, hit etc.) or internal (bra...

Introduction to posture: Posture is a state or attitude attained by the body either during work or during rest. How a person is standing, sitting or even lying is determined by the posture adapted by the individual. But in all the above mentioned situations the person’s body is at rest. Postures attained during a movement or a series of movements also depends on the action of group of muscles helping the body to attain such rapidly changing positions along with stability. The simplest example can be of walking, the mechanism of gait is governed by several small portions of movements making up a chain of movements called as gait. Let’s have a deeper look at what is the difference between these types of postures. Types of postures: Postures can be broadly classified into two types: 1. Active postures: The posture assumed by the body when the person is active. Meaning, that the body’s muscles are at work and are contracting to keep the body stable and to achie...
