Question

The  active  length-force relation of skeletal muscle is characterised by an optimal length (L O ) at which:

Answer

the width of the I band in the sarcomeres is at a minimum.

Answer

the thin filaments from either end of the sarcomere are overlapping each other.

Answer

a fully fused tetanic contraction produces maximum force.

Answer

summation is no longer effective and twitch contractions are sufficient to give maximum force.
