Figure 9.

Calcium responses and fluid flow in a simulated cell. (A): the cell membrane, showing the triangles used in the finite element mesh. Red triangles are apical membrane and blue triangles are basal membrane. The lateral membrane (which abuts neighbouring cells) is omitted for clarity. The green circles show the places for which the ${\mathrm{Ca}}^{2+}$ responses are plotted in panels (C,D). (B): total fluid flow plotted over time for three different stimulation levels. (C,D): ${\mathrm{Ca}}^{2+}$ responses from seven different positions in the cell, denoted by the green circles in (panel A).
