bilaminar
Having two layers
Bilaminar means having two layers.
The term appears in anatomy and embryology, where the bilaminar disc is an early stage of embryonic development consisting of two cell layers: The bilaminar embryonic disc forms during the second week of development.
Technical contexts may use it for any two-layered structure or membrane.
