Abstract
The cochlea outer hair cell (OHC) is a sensory receptor cell that exerts a force when electrically stimulated. In order to analyze the mechanical properties of OHC and its force generation, a mathematical model was used based on a neural modeling program Genesis. The model was implemented as a thin-shell fluid-filled closed cylinder whose passive membrane properties were described by two elastic parameters: area modulus and shear modulus. The axial compliance of the model cells increases linearly with length. The force generated against a constant load increases with the cell length. The isometric force is independent of cell length but dependent of the two elastic parameters.
