The only locks I have heard of in vertebrates appears to be the case of the tendons running in the toes of perching birds when they go to sleep. Looking around, I found something from Manfrotto called a Magic Arm which might presumably help in this kind of situation. Anyway Manfrotto is unaffordable but their idea suggests that their designers had only seen human bone joints. A plain tripod is extremely difficult to use when you have to move around on uneven terrain covered by vegetation. It seems like the human arm, at least mine, does not have any locking structures. So when putting out their pseudopodia they would let their internals flow in and then gellify it so that they can move in a particular direction. The illustration used to suggest that the viscosity of their cytoplasm could be changed....
