Grahic Jump Location
(a) Hair cell showing the bundle extending out of the apical surface (AS). The dark mass is the cuticular plate (CP). (b) A close up of the bundle shows drop-off in cilia height and three-dimensional arrangement. (c) Single stereocilia usually taper at their base. (d) Side view of two neighboring cilia depicts geometry of tip link (dark) and side links (light). (e) Top view of bundles shows in the distribution of tip links towards the tallest neighbor. (f ) Side links extend in the direction of every neighbor.

(a) Nodal degrees of freedom showing the deflections and rotations, and (b) loads for each stereocilia element
Grahic Jump Location
Link representation as a rod with end points i and j, showing global (x,y,z) and element local (x*,y*,z*) coordinates. Such a member resists deformation and carries forces only along its long axis, here x*.
Grahic Jump Location
Top view of two stereocilia connected by links: (a) undeformed configuration; (b) deformed geometry without the consideration of link extension. Such a treatment would result in underestimation of link displacement. (c) Method used to compute the geometry with link extension.
