A. hinge joint
B. ball-and-socket joint
C. pivot joint
D. gliding joint
Correct Answer:
Option A – hinge joint
Explanation
The knee joint is one of the strongest and most important joints in the human body. It allows the lower leg to move relative to the thigh while supporting the body’s weight.
Movements at the knee joint are essential to many everyday activities, including walking, running, sitting and standing.
The knee, also known as the hinge joint (tibiofemoral joint) formed between three bones: the femur, tibia, and patella.
A gliding joint, also known as a plane joint or planar joint, is a common type of joint formed between bones that meet at flat or nearly flat articular surfaces.
Pivot joint, also called rotary joint is a freely moveable joint that allows only rotary movement around a single axis. Pivot joints also provide for the twisting movement of the bones of the forearm (radius and ulna) against the upper arm.
The ball and socket joint (or spheroidal joint) is a type of synovial joint which enables the bone to move in many places (nearly all directions). These are found in the hip.
