Answer:
involuntary movements
Step-by-step explanation:
Involuntary movements are those that happen without the person having control over them. Some are part of our normal functioning, such as heartbeat and bowel movement, but others may happen that are unnatural. They affect virtually all parts of the body, such as the neck, face, arms, legs and trunk, which can move alone or together. One of the most common involuntary movements is tremor, but we can use as an example of involuntary movement the information Dean's brain sent to his body alerting the right time to breathe.
