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 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.


What is the function of the transverse tubules in muscle activation?

Transverse tubules are extensions of the cell membrane that allow action potentials to quickly penetrate into the interior of muscle cells. This helps in triggering the release of calcium ions from the sarcoplasmic reticulum, which is essential for muscle contraction.
