WebMar 27, 2024 · When muscle contracts, the H zone (central region of Azone) which consists of thick filaments is shortened and the I band which contains only thin filaments is also shortened during the time of contraction. Note: Based on two variables the muscle contraction can be described such as length and tensions.
What Happens To H Zone During Muscle Contraction?
WebMar 13, 2024 · The H zone—the central region of the A zone—contains only thick filaments and is shortened during contraction. What happens to the filaments during muscle contraction? The A band stays the same width and, at full contraction, the thin filaments overlap. When a sarcomere shortens, some regions shorten whereas others stay the … WebMay 17, 2024 · The A band stays the same width, but the H-zone shortens or disappears.
