Sarcomere Structure : Mnemonic

Remember the sequence: Zahir Is A Hungry Man

1. Z line (Zwischen = between [German])
2. I band
3. A band
4. H zone
5. 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)
