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 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.
What happens to the bones when muscle shortening
The connective tissue covering that encloses the sarcolemma of an individual muscle fiber is called endomysium. It surrounds each muscle fiber and provides support and protection to the muscle cells.
