Information on muscle length is essential for the regulation of posture and movements. This informationis provided to the central nervous system by the sensory endings of the muscle spindles. The primary endings possess a dynamic sensitivity that is much greater jkfor small than for large amplitude changes. This sensitivity is due to the properties of certain intrafusal muscles fibres, the nuclear bag fibres, and their sensory terminals.
