nervous system
• while embryos show normalized abducens exit and fasciculation, abducens nerve stalling is increased in the abducens fasciculation region, with both reduced abducens nerve length and thinner nerve diameter near the orbit
• stalled projections do not stay within normal nerve boundaries and instead wander to track with the mandibular and cervical branches of the facial nerve
|
• abducens nerve length is reduced in embryos and nerve diameter is thinner near the orbit
