suppose you were to activate a skeletal muscle fiber that is at a very short length such that the thin filaments from opposite sides of the sarcomere ran into each other and the m-line? what would happen to skeletal muscle fiber force production at that length when an action potential was generated?

Answer :

Skeletal muscle fiber force production at that length when an action potential was generated will the sarcomeres would generate very little force.

The fundamental unit of contractility for muscle fiber is the sarcomere. Actin and myosin, the active components involved in muscle contraction, make up each of the two primary protein filaments that make up a sarcomere.

In skeletal muscle, the sarcomere serves as the primary contractile unit of muscle fiber. The thick filaments known as myosin and the thin filaments known as actin make up the majority of each sarcomere's protein filaments (myofilaments).

Because the actin and myosin filaments that drive skeletal and cardiac muscles' contraction are arranged into repeating arrays called sarcomeres, which have a striated microscopic appearance, these muscles are referred to as striated muscles.
