Definition

1. Noun:
   • The ulna: The inner and longer of the two bones in the human forearm, running from the elbow to the wrist on the side opposite the thumb. It is a key bone in the formation of the elbow joint.

Usage

• The term "elbow bone" is a common, non-technical name for the ulna. It is used in everyday language or introductory contexts to refer to this specific bone, emphasizing its location near the elbow.
• It is typically used as a singular, countable noun.

Examples

• Noun:
  • He felt a sharp pain in his elbow bone after the fall.
  • The doctor explained that the fracture was in the elbow bone, or ulna.

Advanced Usage

• While "elbow bone" is understandable, the precise anatomical term is ulna. In medical, scientific, or formal contexts, "ulna" is always preferred.
• The phrase can be used descriptively to indicate location or involvement of that specific bone.

Variants and Related Words

• Ulna (n): The standard anatomical term for the elbow bone.
• Radius (n): The other, shorter bone of the forearm, located on the thumb side.
• Olecranon (n): The large, bony prominence of the ulna that forms the point of the elbow.

Synonyms

Notes on Meaning

• "Elbow bone" refers specifically to the ulna, not the collection of bones at the elbow joint. It does not refer to the humerus (upper arm bone) or the radius.
• The name is derived from the bone's prominent role in forming the elbow joint.
