Involuntary muscle movement includes peristalsis in the GI tract and the beating of your heart. Generally involuntary muscles are smooth muscles (intestines, blood vessels), but the cardiac muscles are sometimes categorized as striated due to their structural similarities to skeletal muscles.
The muscular system directly causes movements and facial expressions by contracting and relaxing muscles in response to stimuli from the nervous system. The coordination between the nervous system and muscular system allows for a wide range of movements and facial expressions to occur.
Smooth muscles
GABA is an inhibitory neurotransmitter that plays a role in the basal ganglia of the brain. The basal ganglia is related with movement and coordinates with the cerebellum in order to control our movements. GABA neurotransmitters are destroyed in Huntington's disease, which causes an imbalance in motions because of the decreased inhibitory neurotransmitters. This causes the involuntary movements that are characteristic of Huntington's.
Opposing muscles use connective tissues to cause movement in a joint.

Birds twitch as a way to adjust their balance and maintain stability while perched or moving. This behavior is caused by their nervous system sending rapid signals to their muscles, helping them make quick and precise movements to stay steady.
The causes of loose abdominal muscles include extreme weight loss and pregnancy.
volcanos and earthquakes
The muscles do not have enough oxygen for aerobic respiration.
