What features are common to forearm movement at an elbow joint and the opening of a cell membrane passageway?

At both the gross anatomical and chemical levels, structure and function are interrelated. The hinge-like movement at the elbow joint depends on the three-dimensional shapes of the joint-forming ends of the humerus and ulna. The opening of a membrane passageway depends on the proper three-dimensional shapes of chemical messenger and the cell's membrane receptor molecule.
