Complex motor tics appear slower and more deliberate than simple motor tics
The cerebellum is the part of the brain that coordinates complex somatic motor patterns by integrating sensory information and coordinating movement.
The most complex forms of life, such as animals, began to appear during the Cambrian period around 541 million years ago. This period is often referred to as the "Cambrian Explosion" due to the rapid diversification and emergence of various complex organisms.
a combination of different brain regions and neural pathways. These activities involve coordination of multiple muscles and require the integration of sensory information. The primary motor cortex, cerebellum, and basal ganglia play key roles in planning, executing, and refining complex motor movements. Additionally, sensory areas, such as the somatosensory cortex, provide feedback to help monitor and adjust movements.
Yes, hexane is generally soluble in motor oil. Hexane is a non-polar solvent while motor oil is a complex mixture of hydrocarbons, so they are likely to mix together.
The cerebellum is the part of the brain responsible for planning and coordinating complex motor activities. It receives information from the sensory systems, the spinal cord, and other parts of the brain to fine-tune movements and maintain balance.
Tics may be motor or vocal
Complex vocal tics involve meaningful words, phrases or sentences
Complex tics are coordinated patterns of stepwise movements that involve multiple muscle groups
Complex tics consist of a repeated pattern of movements that can involve several muscle groups and usually occur in the same order.
The only real way to diagnose the condition is to talk to a specialist, but in general, tourettes is characterized by an involuntary tic, noise or speech pattern. The popular concept of Tourette's is involuntary verbal expression, in some cases as incoherent words or offensive ones. Most Tourette's cases do not include such unusual speech.

Distinguishing between certain complex motor tics and certain compulsions (e.g., repetitive touching) can be a problem. By convention, tics are distinguished from "tic-like" compulsions (e.g., compulsive touching or blinking) based on whether the patient attaches a purpose or meaning to the behavior. For example, if a patient feels an urge to repeatedly touch an object, this would be classified as a compulsion only if it was preceded by a need to neutralize an unwanted thought or image; otherwise it would be labeled a complex motor tic. Tics are often identified by "the company that they keep": if a complex motor act is accompanied by clear-cut tics (e.g., head jerks), it is most likely a tic itself.
A repetitive movement that is difficult, if not impossible, to control. Tics can affect any group of muscles. The most common are facial tics, such as eye- blinking, nose-twitching, or grimacing. Tics that affect the muscles used to produce speech are known as vocal tics, and can range from grunts or whistles to the repetition of complete words or phrases. Complex motor tics involve multiple, sequenced movements, and can include behaviors such as twirling in place, tapping a certain number of times, or stooping to touch the ground. You can have a tic without having Tourette's Syndrome. Tourette's syndrome is a disorder that prominently features tics, often to the point of causing significant distress and problems functioning. It is more common in people with ADHD, obsessive compulsive disorder and anxiety but it can occur on its own.
Uhh, no.
Jumping is a complex motor tic
Pinching is a complex motor tic
Smelling is a complex motor tic
Twirling about is a complex motor tic
