abnormal nervous system morphology ( J:159834 )
• mice exhibit abnormal development and patterning of the peripheral nervous system compared with wild-type mice
abnormal axon fasciculation ( J:159834 , J:206541 )
• mice exhibit defasciculation of the ophthalmic branch of the trigeminal ganglia compared with wild-type mice (J:159834)
• defasciculation of the ophthalmic branch of the trigeminal ganglion axons within the face (J:206541)
abnormal trigeminal nerve morphology ( J:206541 )
• defasciculation of the ophthalmic branch of the trigeminal ganglion axons within the face
• however, the maxillary and mandibular branches are largely unaffected
abnormal ophthalmic nerve morphology ( J:159834 , J:206541 )
• mice exhibit defasciculation of the ophthalmic branch of the trigeminal ganglia compared with wild-type mice (J:159834)
• axons within defasciculated bundles occupy a loosely defined tract and spread out prematurely within the face unlike in wild-type mice (J:159834)
• defasciculation of the ophthalmic branch of the trigeminal ganglion axons within the face (J:206541)
