What is joints and its function?
A joint is defined as the juncture where bones and muscles come together, facilitating movement and stability. Contraction of muscles crossing the joint can stabilize it or cause it to move. Normal joint function is defined as a joint’s ability to move throughout its range of motion and bear weight.
What bones make up the hinge joint?

Can hinge joint move in all directions?
Like a door, these joints can move back and forth, but cannot swivel or move in any other directions. Though ginglymi only move on one plane, they allow a very large range movement on that plane, which is why they are found in the limbs. Like a hardware hinge, every joint in the body must be lubricated.
How many hinge joints are in the human body?
Hinge joint 1 : Ball and socket joint ; 2 : Condyloid joint (Ellipsoid); 3 : Saddle joint ; 4 Hinge joint; 5 : Pivot joint ; Metacarpophalangeal articulation and articulations of digit.
What is the hinge joint structure?
A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. The simplest hinge joints in the body are the interphalangeal joints found between the phalanges of the fingers and toes.
What is the movement of the hinge joint?
A hinge joint is a joint that moves uniaxially. Elbows, knuckles and knees are hinge joints. They are designed to allow side-to-side motion along with back-and-forth movement. The hinge joint is made of strong ligaments, which are covered with cartilage.
