title: Development of the muscle spindles in the human fetal oblique muscles of the eyeball.
abstract: The development of muscle spindles in human oblique eye muscles was investigated in 22 fetuses aged 12 to 24 weeks. The muscle spindles appear at 12th week as 1-2 intrafusal fibers surrounded by capsule. With advancement of the development the number of intrafusal myofibers increases. In 14th week the capsule is composed of 2 layers and in 17th week the external capsule appears.
