Probability density distribution of mechanical parameters of PC12 neurites, obtained from the fit of the experimental and theoretical PSD (Equation 3, Figure 2C red continuous line). (A) Effective neurite viscosity ${\eta }_s^e$. (B) Neurite axial tension σ. (C) Neurite flexural rigidity $\mathcal{B}$. (D) Effective membrane viscosity ${\eta }_m^e$. (E) Membrane surface tension γ. (F) Membrane bending rigidity $\mathcal{K}$. (G) Membrane to cytoskeleton coupling ρ_bk. All experimental probability distributions were fitted by a Log-Normal distribution. N = 75 neurites of similar radius and length.
