Man never made a rivet like this: double sided ductile suspension shear load lap rivet

haha…. you think i am joking: just contemplate the desmosome

1) velcro (desomogleins desmocollins) rivet proteins with central hooks in the intercellular space
2) lapping surfaces (trilaminar membrane from two adjacent cells) penetrated by the desmogleins and desmocollins
3) intracellular lock washers (the plakoglobin and plakophilin linking to the desmogleins and desmocollins after their transmembrane pass) reinforcing the rivet body
4) suspension flexibility perpendicular to the cell membranes (desmoplakins which attach to the plakoglobin and plakophilin lock washers) absorbing both shear and
5) intermediate filament (ropes for applying resistace and tension to the desmoplakins which lie parallel to the plasmalemma NOT hairpin like most diagrams put them)
