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 structure is part of a muscle cells membrane that delivers signals to sarcomere?

The transverse (T) tubules are structures in a muscle cell's membrane that deliver signals from the cell surface to the sarcomeres, which are the contractile units of the muscle cell. These T-tubules help coordinate muscle contraction by allowing the signal for muscle contraction to penetrate deeply into the cell.


Enlarged portion of sacroplasmic reticulum on either side of a transverse tubule?

These structures are called terminal cisternae, and they function to store and release calcium ions during muscle contraction. The close proximity of terminal cisternae to transverse tubules allows for efficient communication and regulation of calcium release during excitation-contraction coupling in muscle cells.


What has the function of transmitting a muscle impulse into the interior of the cell?

Transmitting a muscle impulse into the interior of the cell involves depolarization of the cell membrane through the opening of voltage-gated sodium channels, allowing sodium ions to rush into the cell. This depolarization then triggers the release of calcium ions from the sarcoplasmic reticulum, leading to muscle contraction.

Enhance cellular communication passage for nervous stimulation during muscle contraction.

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.


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.
