Proper digital arteries

Proper digital arteries are blood vessels that supply blood to the fingers and toes. These arteries are crucial for the delivery of oxygen and nutrients to the tissues of the digits, ensuring their proper function and health.

Anatomy

The proper digital arteries are branches of the common digital arteries, which in turn arise from the superficial palmar arch in the hand and the plantar arch in the foot. Each proper digital artery runs along the sides of the digits, typically accompanied by a corresponding digital nerve.

Hand

In the hand, the proper digital arteries originate from the common digital arteries, which are branches of the superficial palmar arch. They travel along the sides of the fingers, providing blood supply to the phalanges, interphalangeal joints, and surrounding tissues.

Foot

In the foot, the proper digital arteries arise from the common digital arteries, which are branches of the plantar arch. They run along the sides of the toes, supplying blood to the phalanges, interphalangeal joints, and adjacent tissues.

Function

The primary function of the proper digital arteries is to deliver oxygenated blood to the digits. This is essential for maintaining the health and functionality of the fingers and toes. Proper blood flow through these arteries is crucial for activities that require fine motor skills and for the overall sensation in the digits.

Clinical Significance

Proper digital arteries can be affected by various medical conditions, such as Raynaud's phenomenon, peripheral artery disease, and diabetes mellitus. These conditions can lead to reduced blood flow, causing symptoms like pain, numbness, and in severe cases, tissue necrosis.
