MEDICAL PHYSIOLOGY

Detailed explanation-1: -A hinge joint is a type of synovial joint that exists in the body and serves to allow motion primarily in one plane.

Detailed explanation-2: -Planar joints have bones with articulating surfaces that are flat or slightly curved faces. These joints allow for gliding movements, and so the joints are sometimes referred to as gliding joints. The range of motion is limited in these joints and does not involve rotation.

Detailed explanation-3: -The least moveable synovial joint type is a hinge joint. This joint only allows movement along one plane, line the hinges of a door. Other synovial joint types allow for movement in two or three planes or in any direction along a flat plane.

Detailed explanation-4: -Ball-and-socket joints possess a rounded, ball-like end of one bone fitting into a cuplike socket of another bone. This organization allows the greatest range of motion, as all movement types are possible in all directions.

Detailed explanation-5: -Hinge joint – the two bones open and close in one direction only (along one plane) like a door, such as the knee and elbow joints. Condyloid joint – this permits movement without rotation, such as in the jaw or finger joints.
