Spiral Ganglion
The spiral ganglion is a spiral-shaped mass of nerve cell bodies.
G - ganglion cells
A - afferent fibres
E - efferent fibres

Organ of Corti
T - tunnel of Corti. located at the center of the organ, appears as a triangular-shaped canal bounded on each side by a single row of tall columnar cells.
TM - tectorial membrane

Cochlea
SM - scala media. roughly triangular in cross-section, with the apex attached to a spicule of bone
SL - spiral limbus
SV - scala vestibuli. originating in the vestibule near the oval window and the base of the stapes; vibrations are conducted towards the apex of the cochlea in the perilymph of the scal vestibuli. SV is located above SM.
ST - scala tympani. below the SM is the perilymphatic space which spiral down from the apex to the secondary TM.
BM - basilar membrane. the membrane separating the SM and the ST. supports the organ of Corti.
SLig - spiral ligament. laterally attached to the basement membrane.
SVasc - stria vascularis. the thickened outer wall of the SM. Is highly vascularized and lined by stratified epithelium.
VM - Reissner's membrane. membrane between the SM and SV. both sides are lined with spimple squamous epithelium.
