Surface processes of olfactory receptors.
The free surface morphology of olfactory receptor cells from the nasal mucosa of Cynomolgus monkeys was studied electron microscopically. The receptor cell, in addition to showing characteristic cilia, possess several branched or unbranched shorter elevations or spiny processes covered by numerous delicate lace-like filaments not previously described. These filaments diminish in length and number toward the base of the microvillous protrusions.
