Is the concentration of calcium ion greater in the sarcoplasmic reticulum or sarcoplasm of a resting muscle?
The Ca2+ ion concentration of the sarcoplasmic reticulum will be greater in a resting muscle
What is the organelle that stores calcium in resting muscle cells?
The Sarcoplasmic Reticulum stores calcium and releases it through the terminal cisternae into the tubule.
Resting muscle generates most of ATP?
In a resting muscle you have few muscle fibres, which contract in batches to give you muscle tone. You have got maximum ATP molecules, generated in resting muscle.
What causes the rapid change in the resting membranes potential that initiates an action potential?
In muscle cells the inward current is a sodium + calcium flow through acetycholine activated channels as well as through voltage sensitive calcium channels.
What is resting tension in a skeletal muscle called?
muscle tone
What is the treatment to muscle strain?
Resting, Icing, compressing, elevating the muscle
Where is calcium stored in a relaxed skeletal muscle?
yes calcium is stored in muscles as it is necessary for muscle contraction and muscle contraction is very sensitive to the amount of calcium
What minerals are needed for normal muscle contraction?
Calcium
What has to relax to a resting state after muscle contraction?
a cramp
Why would a calcium channel blocker lower Cardiac Output?
One of the factors that make muscles contract is the release of calcium onto the muscle fibers. An electrical signal is sent into the muscle and stimulates the sarcoplasmic reticulum to release calcium along the muscle. A calcium channel blocker may reduce the muscle's contact with calcium and could possible explain why the heart has lower output.
After nervous stimulation of the muscle cell has ceased the calcium in the muscle?
uhhh
What would happen to a muscle's ability to contract if calcium levels within the muscle were low?
Muscles cannot contract without calcium
