A twitch is when only one muscle is affected, usually the result of a nerve impulse, while a spasm is when multiple muscles contract involuntary, due to a chemical imbalance.

What occurs when a muscle contracts spasmodically and involuntary?
The a voluntary muscle contracts involuntarily, you will see a little movement through your skin. These movements are often called Tics, Twitches, and Spasms. If the involuntary contractions are widespread and very energetic, they may be called, "Seizures".
Why would a person may shiver?
Muscle contract and expand involuntarily to produce heat
What type of muscle tissue lines hollow structures like ducts and blood vessels that contract involuntarily?
Smooth muscle (involuntary)lines ducts and vessels.
Why can I make a rumbling noise in my ears?
The rumbling noise in your ears is likely caused by the contraction of a small muscle in your ear called the tensor tympani muscle. This muscle can contract involuntarily in response to certain sounds or movements, creating the rumbling sensation.
What muscle types are involuntarily controlled?
Skeletal muscle
What are the two muscle types?
One type of muscle is called smooth muscle. A smooth muscle works involuntarily. The other type of muscle is called skeletal muscle. Skeletal muscle only works with a command.
What is the physiology behind muscle cramps?
Muscle cramps occur when muscles contract involuntarily and do not relax. This can happen due to various reasons such as dehydration, muscle fatigue, or electrolyte imbalances. When a muscle cramps, the normal communication between the nerves and muscles is disrupted, causing the muscle to contract and stay contracted. This can lead to pain and discomfort until the muscle relaxes.
Why do we get muscle cramps and what are the possible causes behind them?
Muscle cramps occur when muscles contract involuntarily and do not relax. Possible causes include dehydration, electrolyte imbalances, muscle fatigue, poor circulation, and certain medical conditions.
What is happening at the cellular level during a muscle cramp?
During a muscle cramp, the muscle fibers contract involuntarily and do not relax. This is often caused by an imbalance of electrolytes like calcium and potassium, which are essential for muscle function. The excessive firing of nerve signals can also contribute to muscle cramps.
How does a deficiency in potassium contribute to muscle cramping?
A deficiency in potassium can lead to muscle cramping because potassium helps regulate muscle contractions. When potassium levels are low, it can disrupt the balance of electrolytes in the muscles, causing them to contract involuntarily and result in cramping.
How does a deficiency in potassium contribute to the occurrence of muscle cramps?
A deficiency in potassium can lead to muscle cramps because potassium helps regulate muscle contractions. When potassium levels are low, it can disrupt the balance of electrolytes in the muscles, causing them to contract and spasm involuntarily, resulting in muscle cramps.
Is skeletal muscle involuntarily controlled?
No they are in the buttocks
