MEDICAL PHYSIOLOGY

Detailed explanation-1: -A saddle joint (sellar joint, articulation by reciprocal reception) is a type of synovial joint in which the opposing surfaces are reciprocally concave and convex. It is found in the thumb, the thorax, the middle ear, and the heel.

Detailed explanation-2: -A saddle joint is a synovial joint where one of the bones forming the joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Saddle joints provide stability to the bones while providing more flexibility than a hinge or gliding joint.

Detailed explanation-3: -Four important synovial joints used in most sporting actions are the elbow and shoulder joints in the arm, and the knee and hip joints in the leg. The elbow and knee joints are both hinge joints. A hinge joint is a type of synovial joint that works like the hinge on a door, allowing bending and straightening only.

Detailed explanation-4: -It is also referred to as a plane or planar joint. This joint permits two or more round or flat bones to manoeuvre freely together with none rubbing or crushing of bones. This joint is especially found in those regions where the 2 bones meet and glide on each other in any of the directions.
