Question

The t tubule contributes to muscle movement because it _________ .

Answer 1

Answer:

• The t tubule contributes to muscle movement because it helps in triggering or initiation of the action potential inside the muscle cells.                

Explanation:

1. As, there are number of structures of which activities are required to attain specific posters for the animal body and they play a vital role in making any physical activity either very fast or too slow in nature.
2. And along with this the chemical balance always fluctuates due to the requirement of locomotion or change in posters for the animal's body, as the T tubule has other cellular structures such as the sacromere and fibers which plays a great part in the as whole physical activities of the animal body.

Answer 2

Answer:

The t tubule contributes to muscle movement because it gives a signal to the sarcoplasmic reticulum to release the calcium that activates muscle contraction.

Explanation:

The T Tubules are tubular infoldings of the sarcolemma (the plasma membrane of the muscle fiber) that penetrate through one cell and emerge on its other side. Each of these T tubules is associated with two terminal cisternae, constituting a triad.

When the stimulus for muscle contraction arrives, the T tubule sends the signal to the sarcoplasmic reticulum, which is a big calcium deposit, to release the calcium and the start the muscle contraction process.
