Definition

Noun: A ginglymus is a type of synovial joint, also known as a hinge joint, that allows movement primarily in one plane (like a door hinge). This movement is typically flexion (bending) and extension (straightening).

Usage

The term ginglymus is a technical anatomical term. It is used in medical, biological, and anatomical contexts to describe the specific structure and function of certain joints.

Examples

• The elbow is a classic example of a ginglymus.
• In human anatomy, the knee and the interphalangeal joints of the fingers and toes are also classified as ginglymi.
• The articulation between the humerus and the ulna forms a ginglymus.

Advanced Usage

• The plural form is ginglymi.
• The joint is characterized by a convex surface fitting into a concave surface, which restricts movement to a single plane.

Variants and Related Words

• Hinge joint: The common, non-technical synonym for ginglymus.
• Ginglymoid (adj): Having the form or characteristics of a hinge joint.
  • The ginglymoid articulation allows for smooth flexion.

Synonyms

• Hinge joint

Antonyms

• Ball-and-socket joint (enarthrosis): A joint allowing movement in multiple planes and rotation (e.g., hip, shoulder).
• Pivot joint (trochoid joint): A joint allowing rotation around a single axis (e.g., the joint between the first and second cervical vertebrae).
• Gliding joint (arthrodial joint): A joint allowing only sliding or gliding movements (e.g., between carpal bones).

Noun

1. a freely moving joint in which the bones are so articulated as to allow extensive movement in one plane
