Biology:Intermuscular coordination
Intermuscular coordination describes the coordination within different muscles and groups of muscles. These are used for sceletoral movement, stabilisation of joints, as well as stabilisation of body positioning.[1]
central nervous system is controlling positioning of joints via anticipatory and correcting adaptions of posture, that work against occurring intersegmental forces.[2]
The specific role and hierarchy of certain muscles and their meaning for certain movements is further differentiated within literature.[3][4]
Usage
Joints are stabilised by interacting muscles, so called synergist muscle. Different synergists feature partial similar functions. Therefore a certain movement can be formed out of different combinations and participations of muscles acting on a certain joint.
Even muscles not being in a direct connection towards a certain joint can fulfill a stabilising function for that very joint. For a clear specification of any muscles function it is necessary to measure precisely muscular function of not directly involved muscles within certain movements via elktromyografia.[5]
Complex movement structures are coordinated within the cerebellum via somatosensoric feedback via psychomotoric learning.
Examples
- Vestibulorcerebellum controls balance and eye-movement. Therefore view is stable, hull- and thighmuscles are keeping their tension within movements
- Spinocerebellum coordinates activity of armmuscles towards each other
- pontocerbellum coordinates fingers and their muscles movements[6]
