Intermuscular coordination describes the coordination within different
muscle
Muscle is a soft tissue, one of the four basic types of animal tissue. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Muscle tissue gives skeletal muscles the ability to muscle contra ...
s and groups of muscles. These are used for sceletoral movement, stabilisation of joints, as well as stabilisation of body positioning.
central nervous system
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina. The CNS is so named because the brain integrates the received information and coordinates and influences the activity o ...
is controlling positioning of joints via anticipatory and correcting adaptions of posture, that work against occurring intersegmental forces.
The specific role and hierarchy of certain muscles and their meaning for certain movements is further differentiated within literature.
Usage
Joints are stabilised by interacting muscles, so called
synergist muscle
Anatomical terminology is used to uniquely describe aspects of skeletal muscle, cardiac muscle, and smooth muscle such as their actions, structure, size, and location.
Types
There are three types of muscle tissue in the body: skeletal, smooth, a ...
. 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.
Complex movement structures are coordinated within the
cerebellum
The cerebellum (: cerebella or cerebellums; Latin for 'little brain') is a major feature of the hindbrain of all vertebrates. Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or eve ...

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
