nervous system

• abducens nerve exits with an increased number of defasciculated bundles within the hindbrain, some of which wander dorsally toward the hindbrain or ventrally to track along the developing buccal branch of the facial nerve
• however, a subset of abducens nerve bundles successfully fasciculate within the midway between the hindbrain and orbit and innervate the extraocular muscle anlage at the orbit
• trochlear nerve and first spine projections are unaffected

|
• abducens nerve diameter is greater
• however, abducens nerve length is normal
