Abstract:
In embryos at stage 16 (37 days) the intramedullary roots of the spinal accessory nucleus ascend in the marginal layer of the spinal cord within one segment. These fibers form the intramedullary accessory fascicle of the XIth nerve. This fasciculus was observed in further developmental stages of investigated embryos.
