contraction
contract or "contraction" is when a muscle fiber lengthens or shortens
The noun for muscle shortening is called contraction.
A single muscle cell is called a muscle fiber.
Each muscle fiber is also called a myofiber.
the protein myoglobin pushes along actin to shorten the muscle fiber
a muscle fiber
The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
shortening of the muscle fiber
The protein primarily involved in the shortening of muscle cells to produce movement is actin, which interacts with myosin. During muscle contraction, myosin heads bind to actin filaments, pulling them closer together and resulting in the shortening of the muscle fiber. This interaction is regulated by calcium ions and ATP, enabling coordinated contraction and relaxation of muscles.
The phase between the stimulus of a muscle and the shortening of the muscle is called the latent phase or latent period. During this phase, the muscle is receiving the signal to contract, but actual muscle shortening has not yet occurred. This period is important for the muscle fibers to prepare and generate enough force for contraction.
