I'll assume you mean in the extracellular space, and not inside the muscle cells. Acetylcholine is the neurotransmitter released from motor end-plates to trigger muscle contraction. So it anything BUT relaxes muscles. High levels of Ca ions on the other hand, make the muscle fibers unable to respond to stimuli, so effectively relax the muscle. (Intracellular Ca release causes contraction though!)

How can running affect your water balance- ion balance and temperature?
ion- think it would affect it in a couple of ways: Muscles use ions to do work and therefore need a delicate balance of sodium, potassium and calcium in order to function well. Any type of prolonged exercise would disrupt this balance. More obviously, sweat contains lots of ions. So, the more you exercise the more ions you lose through sweat.

Why do muscles contract and relaxes rapidly?
When muscles contract and relax rapidly it is usually called twitching, or fasciculation. It is usually harmless and sometimes caused by a reflex action through the spinal cord, or from an imbalance in electrolytes in the blood, or even excess calcium inside the muscle cells. Rarely it is caused by a neurological problem. So unless it is constant and severe, it is more likely nothing to worry about.
What are all of the skeletal muscles in the body?
Muscles are set kind off like sets. Muscles can only contract and relax. It takes at least two muscles to move a part of the body fully. For example, when your arm is straight, your triceps (back of your arm) contract and the bicep relaxes. When your move your arm to a l shape, the bicep contacts and the tri relaxes. This happens through out the whole body.
Are there beneficial substances that disslove in water?
yeah there are many disolved substances in water.some being calcium ions,fluoride ions,iron and many more which benefit us
What effect changing the concentration of calcium ions has on the rate of coagulation of milk?
Rennin is an enzyme that converts the soluble milk protein caseinogen into the insoluble protein paracasein, producing the curd that can be processed into cheese or other milk products. Inorganic ions such as metal ions can act as cofactors. The ion may combine with either the enzyme or the substrate to reduce the activation energy. These ions are called activators. Activators are thought to make the enzyme substrate complex form more easily. For example, the action of amylase on starch is quicker in the presence of chloride ions. Calcium ions are required to activate the enzyme rennin. In this demonstration, calcium ion is removed by precipitating it as calcium citrate. In the tube containing the sodium citrate, calcium citrate forms as a precipitate. what effect changing the concentration of calcium ions has on the rate of coagulation of milk how calcium ions influece the activity of rennin in bringing about the coagulation of milk because it does
What are the goodness of calcium?
well it gives you brain power and is very good for your muscles and if you've got white patches on your nails it means that you need more calcium..
How would a decrease in the concentration of calcium ions in the blood affect the process of hemostasis?
coagulation would proceed more slowly
How do I explain this hypothesis 'The higher the amount of calcium hydroxide added the more the pH will increase'?
Calcium hydroxide has a low solubility in water yet if the concentration of hydroxyl ions increase the pH increase.
What compound is formed from sodium bicarbonate and calcium chloride?
When calcium chloride dissolves, it is rather exothermic (which makes it a good deicer for sidewalks). After mixing: the sodium and chloride ions will remain in solution and do nothing. The bicarbonate and calcium will react in a strange way. Ca2+ + 2 HCO3- → CaCO3 + H2CO3 As the calcium carbonate drops out of solution, the equilibrium of this reaction is further driven off to the right thus creating more carbonic acid. Carbonic acid easily decomposed to form water and carbon dioxide. H2CO3 → H20 + CO2 So, when you mix calcium carbonate and sodium bicarb, you get: Carbon dioxide gas, calcium carbonate solid, water and sodium and chloride ions.
Why does the ionic compound calcium fluoride have a different structure from that of calcium chloride?
Calcium fluoride has the fluorite structure where each calxium ion has 8 fluoride ions as near neighbours at the corners of a cube, and eacf fluoride has 4 calcium ions ate the corners of a tetrahedron. Another way of looking at this is that the calcium ions are close packed and the fluroide atoms fill the "tetrahedral holes" In calcium chloride the chloride ion is too large to allow eight coordination and the coordination around the calcium drops to 6, the coordination around the chloride has to drop to 3. This gives CaCl2 a unique structure which is a distorted form of the more regular rutile structure adopted by TiO2.
If factor IV is required for coagulation of blood how is a factor IV deficiency treated?
Factor IV is the presence of calcium ions as a factor for blood clotting. As such, treatment of a deficiency is to provide more calcium to the bloodstream.
