Calcium is actually the main cation (positively charged ion) responsible for muscle contraction. Most people think it is Sodium or Potassium. Sodium is an anion (negatively charged ion) which controls your body's saturation (all the way down to the cellular level) and also aids in transporting minerals. What happens when you are dehydrated? Your muscles cramp up. Potassium is a cation which creates electricity. In muscle movement, sodium and potassium create a channel in which sodium rushes in and potassium rushes out causing the muscle fiber membrane to become more positively charged, triggering an action. This ultimately would not be possible without calcium, which starts the whole process. For more information check out the following link.

∙ 9y agoThe contraction of the muscle of the heart relies on the presence of the calcium-ion element. This was based on the study on the heart of a frog in 1882.

The portion of the nervous system that most closely associated with the contraction of cardiac muscle is The?
The portion of the nervous system that is most closely associated with the contraction of the cardiac muscle is the autonomic nervous system.
What is muscle contraction without muscle shortening is what kind of contraction?
Isometric contraction
The portion of the nervous system that is most closely associated with the contraction of the cardiac muscle is the?
autonomic nervous system
Constant contraction of a muscle is?
constant contraction of a muscle is called the muscle tone
What is a concentric contraction?
concentric contraction is atype of muscle contraction which the muscle shortens while genrating aforce The muscle shortens to produce movement. A muscle contraction in which shortening occurs.
What does the contraction of the gastrocnemius muscle usually result in?
type of contraction of gastrocnemius muscle?
Describe the events of muscle cell contraction?
6 steps in a muscle contraction
What is the difference between isotonic and isometric contractions?
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
What factors affect muscle contraction?
the degree of muscle stretch is affect the strength or force of skeletal muscle contraction
The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
What is a contraction in which the muscle shorten and work is done?
This is muscle flexion or isotonic contraction.
What component is not essential for the process of muscle contraction?
Actomyosin does not seem to be essential for the process of muscle contraction. The most important elements of muscle contraction include potassium and ATP.
