ID
Ductus reuniens - Thin tube connecting the saccule and cochlear duct.
Define: cochlear labyrinth
Contents of the bony labyrinth.
ID 6
Stria vascularis - Broad, highly vascularized strip with specially structured epithelial cells overlying the spiral prominence. It presumably secretes endolymph.

ID
Cavitas tympanica (tympanic cavity) - Oblique crevice situated medial to the tympanic membrane. It contains the auditory ossicles and communicates posterosuperiorly with the pneumatized mastoid cells and anterosuperiorly with the nasopharynx via the auditory tube.
Remember this
ID 11
Promontorium (Promontory of the labyrinthine wall) - Elevation produced by the basal turn of the cochlea.
ID membrane that covers this opening

ID 24
Eminentia pyramides (Pyramidal eminence of the mastoid wall of the tympanic cavity) - Conical, bony prominence at the level of the oval window with a perforated summit. It contains the stapedius and gives its tendon exit through the opening at its tip.
