Motor control is the regulation of movements in organisms that possess a nervous system. Motor control includes conscious voluntary movements, ...
The motor system is the set of central and peripheral structures in the nervous system that support motor functions, i.e. movement. [ 1 ] [ 2 ] Peripheral structures may include skeletal muscles and neural connections with muscle tissues. [ 2 ]
This feedback allows for more fine control of movement. In the brain, proprioceptive integration occurs in the somatosensory cortex, and motor commands are generated in the motor cortex. In the spinal cord, sensory and motor signals are integrated and modulated by motor neuron pools called central pattern generators (CPGs).
The motor cortex is the region of the cerebral cortex involved in the planning, control, and execution of voluntary movements. The motor cortex is an area of the frontal lobe located in the posterior precentral gyrus immediately anterior to the central sulcus. Motor cortex controls different muscle groups
Muscles which possess more motor units (and thus have greater individual motor neuron innervation) are able to control force output more finely. Motor units are organized slightly differently in invertebrates: each muscle has few motor units (typically less than 10), and each muscle fiber is innervated by multiple neurons, including excitatory ...
The motor areas are located in both hemispheres of the cortex. The motor areas are very closely related to the control of voluntary movements, especially fine fragmented movements performed by the hand. The right half of the motor area controls the left side of the body, and vice versa. Two areas of the cortex are commonly referred to as motor:

The major function of this pathway is fine voluntary motor control of the limbs. The pathway also controls voluntary body posture adjustments. corticobulbar tract: from the motor cortex to several nuclei in the pons and medulla oblongata: Involved in control of facial and jaw musculature, swallowing and tongue movements.
