Synovial Hinge Joint Elbow, Elbow Wikipedia

This joint unites long bones and permits free bone movement and greater mobility.

Hinge joint fence post spacing. A joint or articulation articular surface is the connection made between bones in the body which link the skeletal system into a functional whole 1they are constructed to allow for different degrees and types of movement and are classified by both structural design and functionailty2some joints such as the knee elbow and shoulder are self lubricating almost frictionless and are. The elbow joint is functionally a hinge joint allowing movement in only one plane uniaxial. The simplest hinge joints in the body are the interphalangeal joints found between the phalanges of the fingers and toes.

The elbow joint is a complex hinge joint formed between the distal end of the humerus in the upper arm and the proximal ends of the ulna and radius in the forearm. Its articulating surfaces movements stability and the clinical relevance. A hinge joint ginglymus is formed when the cylindrical end of a bone fits into a trough shaped surface of another bone like that of an elbow joint between the humerus and the ulna.

Hinge joints like in your knee and elbow enable movement similar to the opening and closing of a hinged door. A hinge joint b can be seen in places like the elbow and knee which are only allowed to bend in one direction. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend.

These joints act as a hinge allowing flexion and extension in just one plane. It is classed as a hinge type synovial joint. Examples of hing joint.

The examples are elbow joints ankle joints interphalangeal joints. Synovial joints can be further categorized based on function. The pivot joint in your neck allows you to turn your head from side to side.

In this article we shall look at the anatomy of the elbow joint. The elbow is the joint connecting the upper arm to the forearm. Starting at a the pivot joint can be found in the first few cervical vertebrae which must twist and turn to allow for rotation of the head and neck.

A synovial joint also known as diarthrosis joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones constitutes the outer boundary of a synovial cavity and surrounds the bones articulating surfaces. So a type of synovial joint the hinge joint our body also allows movement in a single plane and this is why we call it as a hinge joint. A fibrous capsule encloses the joint and is lined internally by a synovial membrane.

The elbow allows for the flexion and extension of the forearm relative to the upper arm as well as rotation of the forearm and wrist. Also observe that the screen of the laptop or the door is movable but it only in a single plane.
