The lower leg between the knee and ankle, or a leg-like part of something.
From Latin crus meaning 'leg.' This anatomical term entered English through medical Latin, where it referred to the lower limb. The meaning has remained consistent from ancient Roman medical texts to modern anatomy.
Surgeons still use this exact Latin term in operating rooms today—it's one of the few ancient Latin words that never got replaced because it was so precisely useful for describing exactly which part of the body they meant.
