nervous system
• embryos show an increase in the number of abducens nerve bundles following exit from the hindbrain, reductions in both abducens nerve length and diameter at the orbit and larger wandering abducens nerve bundles that exhibit enhanced nerve pausing at the midpoint decision within the abducens fasciculation region
• however, trochlear nerve and first cervical spine projections are normal
|
• abducens nerve length is reduced and nerve diameter is thinner near the orbit in embryos
