Sensory cell orientation mapping of human macula sacculi. Scanning electron-microscopic study.

The surface view of the macula sacculi of man was investigated using scanning electron microscopy to determine the morphological polarization of the sensory hair. The mapping of the macula did not show the regular cell orientation pattern reported by earlier investigators. At the striat region, a clear change in the shift of sensory cell polarization could not be found in the present study.
