The Huxley Model

The Huxley Model describes how muscle fibers produce force by the interaction of two types of protein filaments: actin and myosin. When a muscle is activated, myosin heads attach to actin filaments and pull, causing contraction. The model explains how the number of these connections and how strongly they pull determine muscle strength and speed. It also accounts for how muscles can generate different amounts of force depending on how many connections are made and how fast the muscle contracts, providing a detailed framework for understanding muscle function at the microscopic level.
