What cellular organelle in muscle fiber corresponds to the endoplasmic reticulum?
The sarcoplasmic reticulum in muscle fiber corresponds to the endoplasmic reticulum in other cell types. The sarcoplasmic reticulum is a specialized type of endoplasmic reticulum found in muscle cells, and it plays a key role in calcium storage and release during muscle contraction.
What are the Skeletal muscle cells that function in calcium storage?
Sarcoplasmic reticulum is the type of skeletal muscle cell that functions in calcium storage. It plays a critical role in regulating intracellular calcium levels during muscle contraction and relaxation.
What is the cellular organelle in muscle fiber corrospondin to endoplasmic reticulum?
Sarcoplasmic reticulum (SR) .
What is the smooth endoplasmic reticulum of a muscle cell?
What is a synapse between a nerve fiver and a muscle fiber
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.
Which substance is stored in the muscle's endoplasmic reticulum and then released when a nerve signal stimulates a muscle fiber?
Calcium ions
Molecules pass in and out of the sarcoplasmic reticulum as a muscle fiber contracts and releases?
calcium Ca2+
What is immediate source of calcium ion for muscle fiber?
The immediate source of calcium ion for muscle fiber is the sarcoplasmic reticulum, a specialized organelle within muscle cells that stores and releases calcium ions in response to nerve signals. When a muscle cell is stimulated, calcium ions are rapidly released from the sarcoplasmic reticulum into the cytoplasm, triggering muscle contraction.
What is the significance of the skeletal muscle fiber triad relationship?
The skeletal muscle fiber triad relationship refers to the structural arrangement of a T-tubule sandwiched between two terminal cisternae of the sarcoplasmic reticulum. This triad structure plays a crucial role in excitation-contraction coupling, as it allows for the transmission of action potentials deep into the muscle fiber to trigger calcium release from the sarcoplasmic reticulum for muscle contraction.
The structure storing calcium in the skeletal muscle fibers at rest is the?
The structure responsible for storing calcium in skeletal muscle fibers at rest is the sarcoplasmic reticulum. This organelle regulates the release of calcium ions during muscle contraction to trigger the muscle fiber to contract.
Organelle storing calicium in resting skeletal muscle fibers?
The organelle responsible for storing calcium in resting skeletal muscle fibers is the sarcoplasmic reticulum (SR). It releases calcium ions when muscle contraction is initiated by a nerve impulse. Calcium is essential for muscle contraction as it acts as a trigger for muscle fiber activation.
What does a muscle triad include?
A muscle triad includes one T-tubule and two terminal cisternae of the sarcoplasmic reticulum. This arrangement is responsible for regulating calcium release during muscle contraction in skeletal muscle cells.
