We prove that, if X is a variety over an uncountable algebraically closedfield k of characteristic zero, then any irreducible exceptional divisor E on aresolution of singularities of X which is not uniruled, belongs to the image ofthe Nash map, i.e. corresponds to an irreducible component of the space of arcson X centered in Sing X. This reduces the Nash problem of arcs to understandingwhich uniruled essential divisors are in the image of the Nash map, moregenerally, how to determine the uniruled essential divisors from the space ofarcs.

Exceptional divisors which are not uniruled belong to the image of the Nash map
