Dyskinetic
No, Ataxia is the inability to coordinate muscle activity during voluntary movement. These movements, which are often shaky and unsteady, are most frequently caused by abnormal activity in the cerebellum. Dyskinesia is the distortion or impairment of voluntary movement such as in a tic or spasm.
Apraxia is a cognitive impairment where individuals have difficulty planning and executing purposeful movements even though they have the physical ability to do so. This can affect a person's ability to initiate, coordinate, and carry out voluntary movements.
The distortion or impairment of voluntary movement in the context of tics refers to the involuntary, repetitive muscle contractions or vocalizations that disrupt normal motor control. These tics can manifest as sudden, rapid movements (motor tics) or sounds (vocal tics), which the individual may feel compelled to perform despite being aware that they are inappropriate or unnecessary. This impairment can lead to difficulties in daily functioning and social interactions, as the tics can be distracting and socially stigmatizing. The underlying mechanisms often involve neurological factors, including abnormalities in the basal ganglia and related neurotransmitter systems.
Voluntary motor functions refer to movements that are consciously controlled by an individual, allowing for purposeful actions such as walking, writing, or playing an instrument. These functions are primarily governed by the brain, particularly the motor cortex, which sends signals to the muscles via the nervous system. Unlike involuntary movements, which occur automatically (like reflexes), voluntary movements require cognitive planning and execution. They play a crucial role in daily activities and fine motor skills.
The primary motor cortex, located in the frontal lobe of the brain, plays a crucial role in regulating voluntary movements by sending signals to the muscles. It works in conjunction with other brain regions such as the cerebellum and basal ganglia, which help coordinate and fine-tune motor activity. Together, these areas integrate sensory feedback and plan movements, ensuring smooth and purposeful actions.
The type of conditioning where the response is voluntary and purposeful is known as operant conditioning, as it involves learning through consequences for voluntary behaviors. In contrast, classical conditioning involves learning through associations between stimuli and automatic responses.

Voluntary movements in the brain are controlled by the motor cortex, which is located in the frontal lobe. This area of the brain sends signals to the muscles to initiate and coordinate voluntary movements. Other parts of the brain, such as the cerebellum and basal ganglia, also play a role in coordinating and fine-tuning voluntary movements.
Dystonia
Movements such as reaching, jumping, writing, waving your hand….all these are voluntary movements. You have finely tuned your skills to be able to make these movements when you decide to make them.
