What minerals are needed for muscle contraction and conduction of nerve impulses?
phosphorous.
Why is vitamin D good for the cardiovascular system?
To geta better answer, Google American Heart Association articles from January 2008 and after, with Dr. Wang, Harvard researcher, who stated that smooth muscle contains Vitamin D receptors. Offhand, most likely because Vitamin D enables calcium uptake in the body and calcium is needed in proper amounts for muscle/nerve coordination (proper calcium/sodium/magnesium balance).
What muscle that makes up the heart?
Here you have a special kind of muscle called as cardiac muscles. Cardiac muscle has got fallowing properties. They are automaticity, excitability, conductivity, contractility, rhythmicity, and refractoriness. That means it contracts. It contracts rhythmically. It contracts automatically of it's own. It can be stimulated. It conducts the impulse across the length. Once it contracts, it will not contract for some time again. These properties have many implications. The different types of heart cells contract at different pace. The cells from SA node contract at the rate of about 76 per minute. That of AV node contract at the speed of about 60 per minute. The cells of atrium contract with the speed of in between the both types of cells. The cells of ventricle contract at the speed of about 36 per minute. So the final rate of contraction of the heart is decided by SA node. it is called as pace maker. The impulse has to be conducted across the heart in synchronized manner. For that the heart muscle is designed to conduct the electrical impulse. Once stimulated, the muscle fiber takes some rest. That is needed so that the muscle can function non-stop for years together. The property of excitability is needed so that the muscle can be stimulated by a stimulus.
What is calcium needed for?
Calcium is a very important mineral ,it provides strength to our bones and teeth.
What is a good source of calcium with vitamin d?
Calcium IS a vitamin which is needed for strong bones and to help muscles to contract and expand. Cheese, milk, sardines and yoghurts are good sources of calcium
What minerals are needed for normal muscle contraction?
Calcium
What is needed for living muscle to contract?
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
What is diffused with ATP and needed in muscle relaxation?
Calcium
What minerals are needed for muscle contraction and conduction of nerve impulses?
phosphorous.
What is needed besides calcium for contraction to occur in muscles?
Two others are sodium and potassium.
Can someone die from not having enough of calcium in their body?
Yes - absolutely. Calcium is needed for muscle and nerve function and a lot of other processes.
Are ATP and calcium both needed for muscle contraction to occur?
look in ur freaken book loser.
Why is calcium needed for muscle contraction?
Yes, calcium is necessary for the release of neurotransmitters that cause a muscle to initiate a contraction. Calcium is also needed to bind to the troponin-tropomyosin complex causing it to change position so the myosin head can attach to the actin molecule which results in contraction.
Why are muscle cells needed in the intestine?
So the intestine can contract and son the food passed through the gut can pass on
What organs are needed to make the muscular system work?
You need your brain to send signals to a skeletal muscle telling it to contract.
Why do muscle cells have the most mitochondria in your body?
muscle cells use this myosin heads that use ATP to contract. the enery needed (ATP) is provided by the bast amount of mitochondria. Which is why muscle cells need so much of them.
Which of 2 chemicals listed would be good skeletal muscle relaxant and why chemical A binds to and blocks ACh receptors of muscle cells and Chemical B floods the muscle cells cytoplasm with CA2 plus?
Chemical A would be the best muscle relaxant. Since the muscle relies on ACH as a stimulant, this chemical would inhibit communication between the muscle cell and the neuron thus making it not contract. While Chemical B would cause further contraction of the muscle since calcium is needed to help the myosin head to attach to the actin filliment which creates muscle contraction.
