Let P be a polar space induced by a
quasipolarity on a projective space G. In this article, we give
sufficient conditions for an embedding (i.e. an incidence-preserving map which
is injective on points and lines) of P into a projective space
H to be extendable to an incidencepreserving map from G to
H. As a consequence, we obtain conditions for such an embedding to be
induced by a semilinear map between the overlying vector
spaces.
