As the sarcomere contracts which band becomes smaller? Which band remains the same?

Respuesta :

Anatomy During Contraction

-Sarcomere, itself, is shorter
-H-zone is shorter (part of A-band that doesn't have actin filaments in it)
-I-band gets shorter (part of sarcomere lacking myosin)
-A-band stays the same size (zone that contains myosin)
