Digital arteries
Digital arteries
Digital arteries (pronunciation: /ˈdɪdʒɪtəl ˈɑːrtəriz/) are the arteries that supply blood to the fingers and toes (digits) of the human body.
Etymology
The term "digital" comes from the Latin word "digitus", meaning finger or toe, and "artery" comes from the Greek word "arteria", meaning windpipe or artery.
Anatomy
Digital arteries arise from the palmar arches in the hand and the plantar arches in the foot. They are divided into two types: the proper digital arteries, which supply the sides of the fingers and toes, and the common digital arteries, which branch off to supply the adjacent sides of two digits.
Function
The primary function of the digital arteries is to supply oxygenated blood to the fingers and toes. They also play a crucial role in thermoregulation, as they help control the body's temperature by adjusting the blood flow to the skin of the digits.
