sentence: Our actomyosin model for dendritic filopodia has the following 11 parameters : η , actin viscosity ; ζ , substrate drag coefficient ; σ , myosin contractility ; m , unbound myosin concentration ; v , polymerization velocity of actin at the tip of the filopodium ; T , membrane tension ; κ , curvature of the membrane at the tip of the filopodium ; β , drag coefficient at base of spine ; D , bound myosin effective diffusion coefficient ; k , myosin on rate ; and k , myosin off rate.Of these parameters , T and κ are not independent , as it is possible to rewrite the dynamic equations such that only the combination T κ appears .
