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 does the terminal cisternae of the sarcoplasmic reticulum release?
Calcim
When is calcium pumped into the sarcoplasmic reticulum?
When Ach enters the synaptic cleft (gap) it open chemically gated sodium channels that starts an action potential spreading through the sarcolemma of the myofibril. This action potential spreads down the T-tubules and "shocks" the sarcoplasmic reticulum into releasing calcium ions.
What cellular organelle in muscle fiber corresponds to the endoplasmic reticulum?
Sarcoplasmic reticulum is the cellular organelle in muscle fiber that corresponds to the endoplasmic reticulum.
Terminal cisternae of the sarcoplasmic reticulum release Ca2 when signaled by the?
T tubules
What surrounds myofibrils?
The sarcoplasmic reticulum are the membranous interconnecting channels and sacs that surround and run parallel to the myofibrils.
Organelle storing calicium in resting skeletal muscle fibers?
The sarcoplasmic reticulum (SR). It releases Ca2+ During contraction, and stores it during relaxation.
What are the Skeletal muscle cells that function in calcium storage?
in the sarcoplasmic reticulum of a muscle fiber/cell.
Where is calcium stored in the muscle cell?
The sarcoplasmic reticulum is known for its storage of calcium ions in muscle cells.
Where are the calcium ions stored in a muscle fiber?
In the sarcoplasmic reticulum (smooth er).
What is in the sarcoplasmic reticulum in muscle?
The sarcoplasmic reticulum is a special type of smooth endoplasmic reticulum. It releases calcium ions during muscle contraction and absorbs them during relaxation.
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 cellular organelle in muscle fiber corrospondin to endoplasmic reticulum?
Sarcoplasmic reticulum (SR) .
What does the terminal cisternae of the sarcoplasmic reticulum release?
Calcim
Where is calcium stored in the contractile cells?
Sarcoplasmic reticulum
When is calcium pumped into the sarcoplasmic reticulum?
When Ach enters the synaptic cleft (gap) it open chemically gated sodium channels that starts an action potential spreading through the sarcolemma of the myofibril. This action potential spreads down the T-tubules and "shocks" the sarcoplasmic reticulum into releasing calcium ions.
What are the Less developed Organelles in cardiac muscles?
sarcoplasmic reticulum
