Answer:
The cerebellum (back of the brain) and the brainstem (middle of the brain)
Explanation:
Muscle movement coordination can be<em> voluntary</em> or <em>involuntary</em>. There are different sections of the brain responsible for the two;
- Voluntary movement of muscles is coordinated by the brainstem in addition to other functions such as sneezing, swallowing, vomitting, etc.
- Involuntary coordination of muscles is controlled by the cerebellum in addition to maintaining posture, balance and body equilibrium.
Hence, both the cerebellum and the brainstem are responsible for coordinating muscle movement.
