ginglymoid joint
Học thuậtThân thiện
Definition
- Noun:
- A freely moving joint in which the bones are so articulated as to allow extensive movement in one plane: A ginglymoid joint is a type of synovial joint, also known as a hinge joint, where the convex surface of one bone fits into the concave surface of another. This structure permits movement primarily in a single plane, like the bending and straightening of a hinge.
Usage Examples
- Noun:
- The elbow is a classic example of a ginglymoid joint, allowing flexion and extension.
- The knee, although more complex, functions primarily as a ginglymoid joint.
- Injury to a ginglymoid joint can severely limit the range of motion in that specific plane.
Advanced Usage
- Anatomical Context: The term is primarily used in technical, medical, or anatomical descriptions.
- The articulation between the humerus and ulna forms a ginglymoid joint.
- Biomechanics: Used when discussing the mechanics of movement.
- The design of a ginglymoid joint provides stability while permitting efficient motion in one direction.
Variants and Related Words
- Ginglymus (n): An alternative, less common term for a hinge joint.
- Hinge joint (n): The common, non-technical synonym for a ginglymoid joint.
- Synovial joint (n): The broader category of freely movable joints to which ginglymoid joints belong.
Synonyms
- Hinge joint: The most direct and commonly used synonym.
- Ginglymus: A technical synonym.
Antonyms
- Fibrous joint (n): An immovable joint where bones are connected by fibrous tissue.
- Cartilaginous joint (n): A slightly movable joint where bones are joined by cartilage.
- Ball-and-socket joint (n): A synovial joint (like the hip) that allows movement in multiple planes, contrasting with the single-plane motion of a ginglymoid joint.
