Module 10: Figure hair cell postsynaptic structure



Organization of the endoplasmic reticulum in the postsynaptic region of the efferent fibres (E) in outer hair cells.

The endoplasmic reticulum (ER) is organized into flattened subsynaptic cisternae (SS) that lie immediately below the nerve ending (E). The SS extend out to subsurface cisternae (SC) away from the synaptic region. Reproduced from Int. Rev. Cytol., Vol. 42, Kimura, R.S., The ultrastructure of the organ of Corti, pp. 173–222.
