What causes the release of calcium from the terminal cisternae of the sarcoplasmic reticulum within a muscle cell? rationale: an action potential in the T tubule causes the release of calcium from the terminal cisternae of the sarcoplasmic reticulum.
- What initiates the release of calcium at the terminal cisternae?
- What neurotransmitter stimulates the release of calcium into the sarcoplasm?
- Which initiates the release of calcium ions from the terminal cisternae?
- What triggers the release of calcium from the sarcoplasmic reticulum?
- How does calcium enter the terminal cisternae?
- What causes the release of calcium from the terminal?
- What triggers the release of calcium?
- What releases calcium ions into the sarcoplasm quizlet?
- What triggers the release of ca2+ from the sarcoplasmic reticulum?
- How is calcium released from the sarcoplasmic reticulum quizlet?
What initiates the release of calcium at the terminal cisternae?
Calcium release from the sarcoplasmic reticulum initiates the contraction. Sodium release from the sarcoplasmic reticulum initiates the contraction. Action potentials propagate into the interior of the skeletal muscle fiber.
What neurotransmitter stimulates the release of calcium into the sarcoplasm?
neurotransmitter acetylcholine.
Which initiates the release of calcium ions from the terminal cisternae?
Calcium release from the sarcoplasmic reticulum initiates the contraction. A triad is composed of a T-tubule and two adjacent terminal cisternae of the sarcoplasmic reticulum.
042 How Calcium Ion Release Results In Muscle Contraction
What triggers the release of calcium from the sarcoplasmic reticulum?
In other words, nervous stimulation leads to depolarization of the sarcolemma (muscle membrane) that triggers calcium ions' release from the sarcoplasmic reticulum.
How does calcium enter the terminal cisternae?
Calcium ion release from the SR, occurs in the junctional SR/terminal cisternae through a ryanodine receptor (RyR) and is known as a calcium spark.
What causes the release of calcium from the terminal?
Excitation refers to the release of calcium ions from the sarcoplasmic reticulum. Excitation, in this case, refers to the propagation of action potentials along the sarcolemmasarcolemmaThe sarcolemma (sarco (from sarx) from Greek; flesh, and lemma from Greek; sheath) also called the myolemma, is the cell membrane of a muscle cell. It consists of a lipid bilayer and a thin outer coat of polysaccharide material (glycocalyx) that contacts the basement membrane.https://en.wikipedia.org › wiki › SarcolemmaSarcolemma - Wikipedia. Excitation refers to the propagation of action potentials along the axon of a motor neuron.
Sarcoplasmic Reticulum And T Tubules
What triggers the release of calcium?
In other words, nervous stimulation leads to depolarization of the sarcolemma (muscle membrane) that triggers calcium ions' release from the sarcoplasmic reticulum.
What releases calcium ions into the sarcoplasm quizlet?
- The sarcoplasmic reticulum releases calcium ions (CA 2+) into the sarcoplasm.
The Neuromuscular Junction Initiation Of Muscle Contraction
What triggers the release of ca2+ from the sarcoplasmic reticulum?
In other words, nervous stimulation leads to depolarization of the sarcolemma (muscle membrane) that triggers calcium ions' release from the sarcoplasmic reticulum.
How is calcium released from the sarcoplasmic reticulum quizlet?
Muscle action potential traveling along transverse tubule opens calcium ion release channels in the sarcoplasmic reticulum membrane, which allows calcium ions to flood into the sarcoplasm.
