Preferred Label : lamina of spiral limbus;
Uberon definition : The osseous spiral lamina consists of two plates of bone, and between these are the
canals for the transmission of the filaments of the acoustic nerve. On the upper plate
of that part of the lamina which is outside the vestibular membrane, the periosteum
is thickened to form the limbus spiralis (or limbus laminæ spiralis), this ends externally
in a concavity, the sulcus spiralis internus, which represents, on section, the form
of the letter C. [WP,unvetted].;
