  • Look Inside


The present review concerns the fine structural organization of intrafusal muscle fibers and their sensory innervation of muscle spindle in a variety of vertebrates, aiming to correlate the morpho-logical aspects with the stretch receptor mecha-nism.

The sensory region of intrafusal fibers in differ-ent animal species shows various morphological differentiation which appears to be designed to gain lower viscosity than the contractile polar and extracapsular segments; the sensory region is generally thought to be easily lengthened by extrafusal fiber stretch or fusimotor stimulation.
