Motor control is the regulation of movements in organisms that possess a nervous system.Motor control includes conscious voluntary movements, subconscious muscle memory and involuntary reflexes, [1] as well as instinctual taxes.
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).
For evaluating proprioception's contribution to motor control, a common protocol is joint position matching. [57] The patient is blindfolded while a joint is moved to a specific angle for a given period of time and then returned to neutral. The subject is then asked to move the joint back to the specified angle.
The arm's desired trajectory, Xref(t), is input into the model, which generates the necessary motor commands, ũ(t), to control the arm. Inverse models use the desired and actual position of the body as inputs to estimate the necessary motor commands which would transform the current position into the desired one.
To generate a motor command, first, the current sensory state is compared to the desired or target state. Then, the nervous system transforms the sensory coordinates into the motor system's coordinates, and the motor system generates the necessary commands to move the muscles so that the target state is reached.

A motor program is an abstract metaphor of the central organization of movement and control of the many degrees of freedom involved in performing an action. Biologically realistic alternatives to the metaphor of the "motor program" are represented by central pattern generators .
Holidays are steeped in tradition, whether it’s a handmade gift you give each year or the pressure to cook the holiday meal just how your grandmother used to make it.
Development is age-related but is not age dependent. In regard to age, it is seen that typical developments are expected to attain gross motor skills used for postural control and vertical mobility by 5 years of age. [9] There are six aspects of development: Qualitative – changes in movement-process results in changes in movement-outcome.
