The temporomandibular joints are one of the few synovial joints in the human body with an articular disc, another being the sternoclavicular joint. The disc divides each joint into two compartments, the lower and upper compartments. These two compartments are synovial cavities, which consist of an upper and a lower synovial cavity.

Synovial fluid, also called synovia, [help 1] is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white –like consistency, [1] the principal role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement. [2] Synovial fluid is a small component of the ...

A mechanical linkage is an assembly of systems connected to manage forces and movement. The movement of a body, or link, is studied using geometry so the link is considered to be rigid. [1] The connections between links are modeled as providing ideal movement, pure rotation or sliding for example, and are called joints.
The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of fibrous joint called a syndesmosis with very little movement. The tibia is named for the flute tibia. It is the second largest bone in the human body, after the femur. The leg bones are the strongest long bones as they support the rest of the body.
The mortise and tenon joint is an ancient joint. One of the earliest mortise-tenon structure examples dates back 7,000 years to the Hemudu culture in China's Zhejiang Province. [3] Tusked joints were found in a well near Leipzig , [4] created by early Neolithic Linear Pottery culture , and used in construction of the wooden lining of the wells. [5]
