Muscle spindle Wikipedia

Structure. Muscle spindles are found within the belly of muscles, between extrafusal muscle fibers. The specialised fibers that constitute the muscle spindle are known as intrafusal fibers (as they are present within the spindle), to distinguish themselves from the fibres of the muscle itself which are called extrafusal fibers. Muscle spindles have a capsule of connective tissue, and run
