it is a hinge joint
No, but a finger joint is part of your anatomy.
Typically, a butt joint is stronger than a finger joint due to the larger surface area for glue adhesion. Finger joints rely on interlocking fingers to provide strength, but the end grain of the fingers can be weaker than a straight butt joint.
The finger joint (also known as a comb joint) is made by cutting a set of complementary rectangular cuts in two pieces of wood, which are then glued. To visualize a finger joint simply interlock the fingers of your hands at a ninety degree angle; hence the name "finger joint."
The answer, simply no. A joint's function is to move - if it were unable to, then it would not be a joint.
Skin is officially an organ, so Skin would be the organ attached to that.
