Which of the following best describes the term z line
a) largely made of myosin molecules
b) protein that accounts for elasticity of resting muscles
c) thin filaments are anchored here
d) repeating unit of striated myofibrils
e) storage site for calcium ions

The correct answer is: C) thin filaments are anchored here

The basic unit of striated muscle tissue is sarcomere. The borders of the sarcomere are Z lines where the thin molecules (actin) bind. I-band is the zone that contains only thin filaments. H-band is the zone of only thick filaments (myosin). The A band is the zone in the center of the sarcomere where thick and thin filaments overlap.
