Remember the sequence: Zahir Is A Hungry Man
- Z line (Zwischen = between [German])
- I band
- A band
- H zone
- M line
Z is the final alphabet: Z lines represents the end of sarcomere
M for middle: M line represents the midline of sarcomere
I is a thin letter: I band has only thin filaments
H is a thick letter: H zone has only thick filaments
A is a hybrid of “I” and “H”: A band has both thin and thick filaments (remains constant during contraction)
