Comparative morphology of the two types hair cells from saccule and utricle under inverted phase contrast microscope / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

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. Method:The length and width of two types hair cells were measured besides the length of cilia,and all datas were analyzed statistically.Result: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.ConclnsionTwo 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.
