What are five bodily movements that are involuntary.

Movements of the body are classified as voluntary or involuntary. These movements are controlled by the nervous system which has several divisions such as the ANS (autonomic nervous system), CNS (central nervous system) and PNS (peripheral nervous system). Involuntary movements are controlled by the autonomic nervous system (kind of sounds like automatic). A few involuntary movements would include heart rate (HR). The heart is under autonomic control, we do not tell our hearts to beat, it beats without our input. Peristalsis is another example. This is the autonomic, wavelike movement of the GI tract that serves to propel the food mass through the GI (gastrointestinal) system. Third is the movement of the GE (gastroesophageal) sphinchter which is located at the distal end of the esophagus. The GE sphincter opens to allow food and or fluids into the stomach and closes to prevent gastric contents from splashing back on the esophagus (GERD) gastroesophageal reflux disease or “reflux”. Fourth are glandular movements that cause secretion of hormones directly into the bloodstream. The pancreas for example secretes insulin( a hormone) directly into the blood in response to the blood glucose level. Lastly, a seizure is a type of involuntary movement. Seizures like a grand mal seizure is a storm of electrical activity in the brain that causes uncontrollable muscular movements.
