21. The fibers then often cross over again within the cerebellum to end on the ipsilateral side. 22. The left and right branches supply their respective sides of the face ( ipsilateral innervation ). 23. The remaining 10 % of axons descend on the ipsilateral side as the ventral corticospinal tract. 24. The second line enters the ipsilateral or contralateral femoral artery and advanced to the distal aorta. 25. Damage to the accessory nerve ( XI ) will lead to ipsilateral weakness in the trapezius muscle. 26. Extrapleural pneumonectomy is a more extensive operation that involves resection of the diaphragm, and ipsilateral pericardium. 27. Ipsilateral ( " same side " ) masking is not the only condition where masking takes place.28. It is still undetermined if the spinoreticular tract possesses ipsilateral fibers in addition to those that decussate. 29. They may also arise within the spinocerebellar tract whose origin is located in the ipsilateral spinal cord. 30. Roth enumerates four different types of commitment : participatory, contralateral, executive, and ipsilateral commitments.
