N, number of hair cells. Values were entered into a 2 × 2 ANOVA with categorical variables as in Table 1. Zone effects: Cell width: overall (P < 0.001); C vs. I (P < 0.02); C vs. P (P < 0.001); I vs. P (P < 0.1). Cell height: overall (P < 0.001); C vs. I (P < 0.05); C vs. P (P < 0.001); I vs. P (P < 0.05). Axis effects: Cell height: CL < CT (P < 0.05); PP > PB (P < 0.001).
