A Model Analysis of Tensile Stress in the Toadfish Vestibular Membranes

Table 2

Mean membrane parameters for the toadfish labyrinth*.

Membrane structure	Membrane model shape	Membrane shape coefficient “𝑠”	Membrane thinness ratio “𝑟/𝑤”	Membrane geometric stress factor “(𝑠)(𝑟/𝑤)”	Membrane hoop stress normalized^# “𝑡𝑛”
Ant. Canal	Cylinder	1.0	4.4	4.4	1.0
Lat. Ampulla	Sphere	0.5	12.0	6.0	1.4
Utricle	Cylinder	1.0	17.4	17.4	3.9
