👉 The Brazil veins are a group of superficial veins located on the upper arm, near the elbow. They are named after the Brazilian physician and anatomist João Baptista da Silva de Souza Neto, who first described them in 1852. These veins are superficial and lie close to the skin surface, making them easy to find and palpate. The Brazil veins are often used by physical therapists and athletes as a site for blood flow assessment and venous return enhancement techniques.
