In general, cell deformation is a complex phenomenon caused by external forces acting over the surface of the membrane. For a given distribution of forces, the rate and extent of deformation depend on the intrinsic and extrinsic properties of the cell. The intrinsic properties are inherent to the membrane and cytoplasm and are mechanical in nature. They include bending, shear and area elasticity, shear viscosity and a cytoplasm viscosity. The extrinsic properties pertain to the surface area and volume of the cell. In this paper, the constitutive equations and intrinsic material properties that describe the elasticity (in shear, expansion and bending) and viscosity of the membrane are given and a relation between the bending modulus and area expansion modulus is suggested.
