[Comparative morphology of the two type's hair cells from saccule and utricle under inverted phase contrast microscope].
OBJECTIVE
To explore more reliable standards for identifying vestibular hair cells of saccule and utricle prepared in studies with patch clamp technique under inverted phase contrast microscope.


METHODS
The length and width of two type's hair cell's were measured besides the length of cilia, and all datas were analyzed statistically.


RESULTS
The width and length of cilia of two types hair cells in saccule and utricle from guinea pig were similar. The length of type I was longer than that of type II, so the ratio between length and width was larger and the ratio of the length between cilia and cell body was small.


CONCLUSIONS
Two type's hair cells of saccule and utricle from guinea pig may be distinguished through the ratio of cell body's length and width even the ratio of the length between cilia and cell body, besides the standards before.
