Intermuscular coordination

from Wikipedia, the free encyclopedia

Intermuscular coordination describes the coordination between different muscles and muscle groups. This is used for skeletal movement, joint stabilization, as well as posture and body position stabilization.

The central nervous system controls the joint positions through anticipatory and corrective posture adjustments, which counteract the intersegmental forces that occur.

The role of individual muscles and their importance for individual movements has been further differentiated in science.

application

Joints are stabilized by interacting muscles, so-called synergists . Different synergists sometimes have similar functions. As a result, a particular movement can result from different combinations and involvements of the muscles acting on a joint.

Muscles that are not directly related to a specific joint can also have a stabilizing function for it. In order to clearly define the function of individual muscles, it is helpful to take a close look at special muscles, even those not directly involved in a movement, using electromyography .

Complex movement processes are coordinated in the cerebellum through somatosensory feedback through motor learning processes .

Examples

  • The vestibulor cerebellum controls balance and eye movement. As a result, the view is stable and the core and thigh muscles keep their specific tension in motion
  • The spinocerebellum regulates the activity of the arm muscles in relation to one another
  • The pontozerbellum coordinates the movement of the fingers and their muscles

terminology

Science calls kinetors muscles that handle the skeletal movement during movement. Stabilizers are called muscles which stabilize a joint and prevent unintended movements. Joint moments are movements of a joint. The need for stabilization arises from muscle actions kinetors of two joints, which result in joint moments in both overstretched joints.
