Within the sensory nervous system,<unk>  of the muscle spindle are composed of type II sensory fibers that terminate on nuclear chain fibers and static nuclear bag fibers, but not dynamic nuclear bag fibers. Whereas primary<unk>  respond mostly to rate of change,<unk><unk>  respond mostly to amount of stretch.
Secondary sensory endings
Neuronal ensemble
Postganglionic nerve fibers
Special somatic afferent fiber
Preganglionic nerve fibers
Chemosensory clusters
