Name this most distal layer in developing embryos, located outside the mesoderm and endoderm.
A part of this tissue layer turns into the otic [OH-tik] vesicle and otic placode, which in turn form the sacculus and cochlea [KOHK-lee-uh] in the inner ear. One part of this layer forms the lacrimal gland and optic diverticulum, while another part forms the lens, making this layer primarily responsible for forming the eye. The first of the three germ cell layers to develop in an embryo, it is responsible for the integumentary system. Two parts of this are the neural crest and neural tube, which form most of the nervous system. Name this most distal layer in developing embryos, located outside the mesoderm and endoderm.
