A joint (articulation) is the location at which two bones make contact (articulate). Joints are constructed to both allow movement and provide mechanical support.\n\nStructurally, joints are classified as:\n\nfibrous - bones are connected by collagen. \ncartilaginous - bones are connected by cartilage. \nsynovial - there is a space (synovial cavity) between the articulating bones. \n\nFibrous joints\nIn fibrous joints bones are joined by tight and inflexible layers of dense connective tissue, consisting mainly of collagen fibers. In adults, these are not designed to allow any movement; however, in children, fibrous joints have not solidified and are movable. Examples of fibrous joints are:\n\nCranial sutures, joining the bones of the cranium. \nGomphoses, the joints between the roots of the teeth and their sockets (or alveoli)and in maxilla and mandible.g \n\nCartilaginous joints\nIn cartilaginous joints (also known as synchondroses) bones are connected entirely by cartilage. In comparison to synovial joints, cartilaginous joints allow only slight movement. Examples of cartilaginous joints are the pubic symphysis, the joints between the ribs and the sternum, and the cartilage connecting the growth regions of immature long bones. Another example is in the spinal column - the cartilaginous region between adjacent vertebrae. and are made of cartilage.\n\n\nSynovial joints\nSee synovial joint for details. (The term "Synovial joint" and "Diarthrosis joint" are often used interchangeably, although the first term refers to the structure and the second one to the function.)\n\nFunctional classification\n\nFunctionally, they can be classified as:\n\nsynarthrosis - permit no movement. \namphiarthrosis - permit little movement. \ndiarthrosis - permit a variety of movements (e.g. flexion, adduction, pronation). Only synovial joints are diarthrodial. \n\nSynarthrosis joints\nSynarthroses are joints with very little (if any) mobility. They can be categorised by how the two bones are joined together:\n\nSyndesmoses are joints where the two bones are joined by one or more ligaments. \nSynchondroses are joints where the two bones are joined by a piece of cartilage. \nSynostoses are the fusion of two bones, to the point that they are practically one bone. In humans, the plates of the cranium, initially separate, fuse together as the child approaches adulthood. Children whose craniums fuse too early may suffer deformities and brain damage, as the skull does not expand properly to accommodate the growing brain - a condition known as craniostenosis. \nAmphiarthroses are slightly moveable joints where the two bone surfaces at the joint - both covered in hyaline cartilage - are joined by strands of fibrocartilage. \n\nAmphiarthrosis joints\nMost amphiarthrosis joints are cartilaginou

No!\n\nApophyseal joint:\nThe articulations between the articular facets of adjacent vertebrae, also known as facet joints. The apophyseal joints have thin and loose articular capsules as well as a synovial membrane and menisci.\n\nThe Atlanto-axial joint (articulation of the atlas with the axis) is of a complicated nature, comprising no fewer than four distinct joints.\nThere is a pivot articulation between the odontoid process of the axis and the ring formed by the anterior arch and the transverse ligament of the atlas; here there are two joints: one between the posterior surface of the anterior arch of the atlas and the front of the odontoid process; the other between the anterior surface of the ligament and the back of the process.\nBetween the articular processes of the two bones there is on either side an arthrodial or gliding joint.\nThe ligaments connecting these bones are:\nArticular capsules \nAnterior atlantoaxial ligament \nPosterior atlantoaxial ligament \nTransverse ligament \n\nHope that this helps

Sounds a bit dangerous!  But I;m sure if you google sometime like "hang gliding kits" then you should get somethin?!\n\nGood luck...and be careful!

Yes, sometimes they have to use a ligament from a dead person to fix.  Fotunately, it is much more commonplace now.  Be sure to see a sports doctor.  They have a lot more experience in fixing joints.

If you examined almost any surface under very high magnification, what looked smooth to the naked eye would look like endless mountain ranges in all directions.  If you then place two such surfaces together using weight or another force to join them and tried to move one surface relative to the other, the opposing "mountains" would have to slide up and over each other or even break (shear) the mountain tops.  The resulting resistance to motion is called friction.  When mountain tops are sheared, the energy forcing the motion is converted to extremely high local heat at the molecular level as bonds between millions of atoms and molecules are broken.  Friction causes heat and can quickly destroy an engine bearing that loses its lubrication.\n\nThe high heat of friction can actually cause a lubricant (oil, etc.) to break down and bond (as olifins) to the metal parts making smoother surfaces, especially when the parts are held apart by a film of circulation oil that carries away excess heat to a heat exchanger.  Grease (which is often a mixture of soap and oil) is thicker than oil and can fill the microscopic mountain valleys so that the parts slide on opposing layers of grease reducing friction and heat.\n\nWhen you push on a heavy crate, you must apply enough force to overcome the static friction (sometimes called stiction) and start the crate moving.  Continued motion creates dynamic friction generating a constant supply of heat.\n\nIf you place any object on a board and lift one end, all materials (combinations of board (incline) and object (load) will slide before the board reaches an angle of 45 degrees.  The higher the board angle, the higher the coeficient of friction.  This method can be used to calculate the coefficients of friction for various combinations of materials (board and load).  Ice on teflon has perhaps the least coefficient of friction and is very slippery.  The objects and board should not serve as cogs or act as adhesives to get valid results.\n\nFamily friction (strife) is the only kind of frictioon that can be reduced by flowers or a hug and a kiss.  That may cover most of the other types of friction, right?

Usually mechanical joints cause localized stress risers. If the joints are not carefully engineered and fabricated, the stress risers will cause decreased fatigue resistance.\n\nIt's a rule of thumb, not a mathematical proof. A lightly-loaded structure with joints may be more fatigue-resistance than a heavily-loaded continuous structure. A well-designed joint with correct stress relief and correct fabrication is likely to be less of a problem than a sharp corner machined into a part, even if they both carry equal load.

In anatomy, Flexion is movement whereby bones or other objects are brought closer together. For example, flexion of the arm involves the forearm being brought closer to the arm. Note that flexion only occurs along the sagittal plane, i.e. from the forward to backward direction, and not side-to-side direction, which would be called abduction.

Depends also if it is muscle or fat.  The muscle can overcome the inertia & air friction.

Your arms have to be double jointed to do that. Or you can jump over your hands.

Pivot Joint: This type of joint allows bones to spin and twist around other bones. There are pivot joints in the neck and the radius part of the elbow.

Can be active or passive.  But they are simply exercises to increase the motion at a joint.
