What is the function of the tubules?

Answer 1

See this link for nice details...http://people.eku.edu/ritchisong/301notes3.htm

In muscle contraction the transverse tubules transmit the muscle impulse into the inner cell.

Answer 2

Because the whole muscle fiber must contract at the same time, the signal (action potential) (Na+)
is conducted through the cell by transverse tubules (T tubules) which have the same properties as the sarcolemma.

Answer 3

to conduct impulses from the surface of the cell (SARCOLEMMA) down into the cell and, specifically, to another structure in the cell called the SARCOPLASMIC RETICULUM.

Answer 4

To transmit muscle impulses to the cell's interior

Answer 5

They allow the action potential to invaginate into the cell so the endoplasmic reticulum can be signaled to release calcium.

Answer 6

To allow impulses (or electrical signals) to move deeper into the cell.

Answer 7

Release calcium
