Arteria tarsea lateralis

Arteria Tarsea Lateralis is a small artery in the human body, part of the intricate vascular system that supplies blood to the foot. It is a branch of the Dorsalis Pedis Artery, which itself is a continuation of the Anterior Tibial Artery. The Arteria Tarsea Lateralis plays a crucial role in the circulation of blood to the lateral side of the foot, contributing to the overall health and functionality of the foot's musculoskeletal and integumentary systems.

Anatomy[edit | edit source]

The Arteria Tarsea Lateralis originates from the Dorsalis Pedis Artery shortly after it appears on the dorsum of the foot. It courses laterally across the tarsal bones, providing oxygenated blood to the lateral aspects of the foot. This artery is known for its small size and its anastomoses with branches of the Arcuate Artery and the Lateral Plantar Artery, forming part of the arterial network that ensures blood supply to the foot.

Function[edit | edit source]

The primary function of the Arteria Tarsea Lateralis is to supply blood to the lateral part of the foot. This includes the skin, muscles, and other tissues in this region. Adequate blood supply is essential for maintaining tissue health, facilitating wound healing, and supporting the metabolic needs of the foot's musculature during physical activity.

Clinical Significance[edit | edit source]

While specific conditions directly affecting the Arteria Tarsea Lateralis are rare, its significance is often noted in the context of broader vascular disorders or injuries that compromise blood flow to the foot. Conditions such as Peripheral Arterial Disease (PAD) and diabetes can lead to compromised blood flow in the arteries of the foot, including the Arteria Tarsea Lateralis. Injuries to the foot that disrupt the arterial supply can also necessitate a detailed understanding of the foot's vascular anatomy for effective management.
