The thin filaments and thick filaments and their associated proteins are the key functional components of the sarcomere. It is important to be able to identify these components in order to understand their roles in muscle contraction.

True or False

True.

Explanation:

The thin filaments and thick filaments are the most important structural parts of the sarcomere in muscle contraction. When a muscle needs to be contracted, this filaments are the ones that make it happen, they strech or reuce their large (depending on the movement)

Their associated proteins help to give the instriction for the contraction, such as very important minerals involved such as the calcium.
