Nevermind z-lines change. Princeton was wrong.
TPRH discrete no.110
during skeletal muscle contraction, which band can be seen to to contract under microscope
A. the i band and h zone
D. the z line
Princeton: Z lines are ends of sarcomere. the length of these do not change during contraction
Kaplan: Z-lines, I-band and H-zone--all of the get smaller or closer together during contraction because they are defined relative to one another
Anyone have EK or BR to finalize who is right?
