Princeps pollicis artery
Princeps pollicis artery is a major artery in the human hand. It is responsible for supplying blood to the thumb and the index finger. The name "Princeps pollicis" is derived from Latin, with "Princeps" meaning "principal" and "pollicis" referring to the thumb.
Etymology
The term "Princeps pollicis artery" is derived from Latin. "Princeps" translates to "principal" or "chief" in English, indicating the artery's primary role in supplying blood to the thumb. "Pollicis" is the genitive singular form of the Latin word for thumb, "pollex".
Anatomy
The Princeps pollicis artery originates from the Radial artery, one of the major arteries supplying the hand. It travels along the thumb side of the index finger, branching into two smaller arteries that supply the thumb and the radial side of the index finger.
Clinical significance
The Princeps pollicis artery is of clinical significance due to its role in blood supply to the thumb and index finger. Damage to this artery can lead to ischemia and necrosis of these digits. It is also of importance in reconstructive surgery, particularly in the creation of thumb and index finger flaps.
