Definition

Noun: 1. The leg from the knee to the foot: In human anatomy, this term specifically refers to the lower leg, the segment between the knee and the ankle. It is a formal or technical term. 2. A leg-like part or structure: In biology and anatomy, "crus" can refer to any anatomical structure resembling a leg or a supporting column, such as certain parts of the brain (e.g., crus cerebri) or internal organs.

Examples of Usage

• Noun (Anatomical):
  • The doctor examined the patient's crus for signs of swelling or fracture.
  • The muscles of the crus are responsible for moving the foot and ankle.
• Noun (Biological):

Notes on Meaning
