Muscle cramps and muscle spasms are symptomes of which heat emergency?
Heat exhaustion This is the loss of vital electrolytes which help contraction of muscles, these being potassium, sodium and magnesium.
Why is potassium important to the cardiac muscle?
All electrolytes are important to all muscles. In the cells there are sodium/potassium pumps that must be balanced. Some electrolytes are positive and some are negative. The balance (inside the cell vs. outside the cell) causes either contraction or relaxation.
Why is the sodium potassium pump important factor of primary active transport?
The sodium potassium pump uses ATP to reach the stimulus and move muscle tissue (primarily skeletal muscle). The threshold stimulus must be reached in order to carry out the full signal.
Conduction of nerve signals and contraction of muscles depends on the proper balance of?
sodium and potassium levels
Which heat emergency are symptoms of Muscle cramps and spasms?
Heat exhaustion This is the loss of vital electrolytes which help contraction of muscles, these being potassium, sodium and magnesium.
Describe the interaction of acetylcholine and calcium ions in stimulating muscle contraction?
The acetylcholine diffuses across the synapse and binds to and activates nicotinic acetylcholine receptors on the motor end plate of the muscle cell. Activation of the nicotinic receptor opens its intrinsic sodium/potassium channel, causing sodium to rush in and potassium to trickle out.
Whats the name of the chemical in the muscular system that causes contraction?
There's more than one chemical that causes contraction. The neurotransmitter (usually acetylcholine) is released from the nerve and excites the muscle. There is a change in calcium, sodium and potassium ion concentrations. ATP is used. All of these work together to produce a muscle contraction.
What element is associated with muscle contraction?
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.

Which electrolyte is important for the activity of the heart muscle?
There are four electrolytes that are important to heart function, potassium, calcium, sodium and magnesium. Calcium is important in the actual contraction of the heart.
What is needed besides calcium for contraction to occur in muscles?
Two others are sodium and potassium.
What minerals are needed for normal muscle contraction?
Calcium
How diuretic absorb in kidney?
A loop diuretic affects the loops of Henle which regulate the uptake of sodium. The diuretic signal the kidney not to absorb calcium, potassium and magnesium and sodium The side effects are muscle weakness , cramps and palpitations.
