Why is a joint important?
A good reason for expansion joints is that they allow for a rise and fall of temperature. If they were not implemented in bridges or building, the intense heat in the summ…er would expand the metal, brick, or concrete materials in a structure and the structure would have cracks and breaks in it. Also, in the winter the harsh cold temperatures would make the materials to contract (come together) and this would also result in disasterous circumstances. All matter's molecules (or all molecules I have heard of) will speed up at higher temperature and slow down at lower temperatures. This is the reason for expansion joints in the first place... too allow expansion without breaking at extreme high and low temperatures. Alternate Answer: They are usually used to accomodate changes in temperature. So if the temperature changes and causes problems or destruction, then the expansion joints are very important, or most important. Have you driven on a poorly designed road in winter where every 100 feet or so there is a heavy bump? Improper design. One road near here has water frozen below the joint or crack area and it causes little humps in the road. They totally ruin the ride quality of the road. Have you had a windshield on a car crack because of cold? When making a wood floor in a house an expansion area is allowed around the floor so it will not buckle or damage the wall. When I was young the school gymnasium would buckle when it was wet. They replaced the whole gymnasium. I designed a fix for a restraunt where the concrete floor was heaving up and down 6 inches, and breaking up the floor, each spring during the thaw when water could get under the foundation. In this case, I rerouted the water under the building so it could build up no pressure under the restraunt. The normal expansion joints for temperature only were fine. This expansion was due to water pressure under the building. The building had worked fine for 20 years until the water flow beneath it changed due to construction further up the hill and increased run-off. Alternate Answer again: An expansion joint is an assembly designed to absorb the stresses produced by the heat and cold atmospheric conditions to the construction materials. The purpose is to hold the whole assembly intact and provide security. Normally large structures like flyovers, stadiums, auditoriums, swimming pools, large buildings have very high impact of summer heat and that leads to expand the construction materials contracting. In the long run, this makes it more vulnerable to cracks. A similar phenomenon happens in the winter and again it makes more vulnerable and affects the life of the structures. Therefore expansion is mandatory to such buildings and large structures. Ref.:architecture.answers.com/equipment/expansion-joint-filler-boards-and-its-importance

Immovable joints in the skull would affect the brain. If the brain moved around due to these immovable parts, then people would have brain damage.
so the brain and skull does not get damaged.

You should have phrased it, "What is the importance of the joints in the skeletal system?" Well you use joints all the time if you don't know that... I will give you an exampl…e of why it's so important. If you only had bones without any joints. You would not be able to bend, or twist. You would be EXTREMELY stiff. It would probably be nearly impossible for you to move. Also you would not be able to play Video Games because you have to bend your fingers or twist and rotate them.
Totally important! The connections must be well made and the wires tightly joined to prevent a loss of voltage to the device powered. In high current situations a poor connect…ion causes heat at the connection and oxididaion of the wires and no more or intermittent connections. Most problems in electrical is not a short but: an open connection. Additional Answer In the case of high-voltage underground cables, the restoration of the insulation is critically important, as is restoring the cable's waterproof integrity. The skills required are such that cable jointers serve a full apprenticeship in that particular trade.
