What's the difference between ectoderm and interlaminar?
Ectoderm
Definition:
(n.) The outer layer of the blastoderm; epiblast.
(n.) The external skin or outer layer of an animal or plant, this being formed in an animal from the epiblast. See Illust. of Blastoderm.

Interlaminar
Definition:
(a.) Between lammellae or laminae; as, interlamellar spaces.
Example Sentences:
