What else can I help you with?
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
Which ion is stored in the sarcoplasmic reticulum?
Calcium ions are stored in the sarcoplasmic reticulum of muscle cells. These ions play a crucial role in muscle contraction by triggering the release of more calcium ions into the muscle cell, leading to the contraction of the muscle fibers.
What would occur if the uptake of calcium ions was blocked in the sarcoplasmic reticulum?
Blocking the uptake of calcium ions in the sarcoplasmic reticulum would prevent muscle contraction. Calcium ions are critical for the release of stored calcium, which activates the muscle contraction process. Without this calcium release, the muscle would not be able to contract effectively or at all.
Normally stored in the terminal cisternae of the sarcoplasmic reticulum?
Calcium ions are normally stored in the terminal cisternae of the sarcoplasmic reticulum in muscle cells. When muscle contraction is initiated, these stored calcium ions are released into the cytoplasm, triggering muscle contraction.
Where are the calcium ions stored in a muscle fiber?
Calcium ions in muscle fibers are stored in the sarcoplasmic reticulum, which is a specialized form of endoplasmic reticulum found in muscle cells. When a muscle is stimulated to contract, the sarcoplasmic reticulum releases calcium ions into the cytoplasm, triggering muscle contraction.
The part of the sarcoplasmic reticulum where calcium ions are stored called?
The part of the sarcoplasmic reticulum where calcium ions are stored is called the terminal cisternae. These structures are found at the ends of the sarcoplasmic reticulum and play a key role in releasing calcium ions into the muscle cell during muscle contraction.
Where are large amounts of calcium stored?
The answer is white, because what are your bones made of? Calcium!
Where are neurotransmitters that cause skeletal muscle contraction are stored?
In the myoneural junction.
Which mineral affects muscle contraction and cardiac function as well as human bones and teeth?
Calcium is absolutely necessary for muscle contraction (both skeletal and cardiac) and for bone and teeth formation. 99% of the calcium in your body is stored in your teeth and bones. It is thought that you should drink as much as 6 glasses of milk a day. That much will not cause gall stones as once was thought.
Where are neurotransmitters that cause skeletal muscle contraction normally stored?
In the myoneural junction.
In certain kinds of muscle cells calcium ions are stored?
Smooth ER
Where in a heart cell is calcium normally stored?
Outside the cardiac muscle cell
