What else can I help you with?
What are the tunnel-like extensions of the sarcolemma into the muscle fiber?
transverse tubules transverse tubules
What are the muscle action potential penetrates into a fiber along the?
Transverse tubules (T-Tubules)
The command to contract is distributed throughout a muscle fiber by the?
Transverse Tubules
What is the function of the transverse tubules in muscle cells?
The transverse tubules in muscle cells help transmit electrical impulses deep into the cell, allowing for coordinated muscle contractions.
What is the function of transverse tubules in muscle cells?
Transverse tubules in muscle cells help transmit electrical impulses deep into the cell, allowing for coordinated muscle contractions.
This transverse structure unique to muscle cells?
T-Tubules, I think...
What is name given to the regularly spaced infoldings of the sarcolemma?
transverse or T tubules
What does the transverse tubules do?
Transverse tubules are extensions of the cell membrane that help to transmit action potentials deep into the muscle fibers. They allow for the rapid and synchronized release of calcium ions from the sarcoplasmic reticulum to trigger muscle contraction.
Irregular transverse thickenings of the sarcolemma?
Irregular transverse thickenings of the sarcolemma connect cardiac muscle fibers to neighboring muscle fibers. The gap junctions that occur with irregular transverse thickening of the sarcolemma allow the myocardium to contract as a single unit.
What is the role of the tubules?
What is the function of the transverse tubules, is it the place where actin and myosin interact or the storage of calcium ions, or to transmit muscle impulses into the cell interior?
The impulse that triggers a contraction travels deep into a muscle fiber by means of what?
transverse tubules
What connects the sarcolemma and the sarcoplasmic reticulum?
The T-tubules, or transverse tubules, connect the sarcolemma (muscle cell membrane) to the sarcoplasmic reticulum (membrane network within muscle cells). T-tubules allow for the rapid transmission of action potentials generated at the sarcolemma to the interior of the muscle cell, triggering the release of calcium from the sarcoplasmic reticulum to initiate muscle contraction.
