**Movement planning and execution** are the products of distributed neural processing involving many areas of the brain[1].
==**The movement initiation** is a function of the motor cortex==, while the coordination and fine-tuning of movements appear to be distributed across several brain centers[2].
**Types of movements[3]**
- **Voluntary Movements**: Controlled consciously.
- **Rhythmic Movements**: Can be consciously initiated but are primarily autonomously regulated by spinal cord/brainstem circuits.
- **Reflexes**: Automatic, stereotyped responses to stimuli, mediated by spinal cord/brainstem (sometimes cortex), and faster than voluntary actions.
In primates, the **primary motor cortex** is crucial in control of fine hand and finger movements[1].
Among all the voluntary hand actions, **grasping an object** is one of most common[1].
