Common plantar digital arteries
Common Plantar Digital Arteries[edit | edit source]
The common plantar digital arteries are important vascular structures in the human body that supply blood to the foot. These arteries are branches of the plantar arch, which is formed by the lateral plantar artery and the deep plantar branch of the dorsalis pedis artery.
Anatomy[edit | edit source]
The common plantar digital arteries are located in the sole of the foot. They arise from the plantar arch and run distally between the metatarsal bones. Each common plantar digital artery bifurcates into two proper plantar digital arteries, which supply the adjacent sides of the toes.
Origin[edit | edit source]
The common plantar digital arteries originate from the plantar arch, which is a crucial anastomosis between the lateral plantar artery and the deep plantar branch of the dorsalis pedis artery. This arch is located deep in the sole of the foot, beneath the flexor digitorum brevis muscle.
Course[edit | edit source]
After originating from the plantar arch, the common plantar digital arteries run forward between the metatarsal bones. They are accompanied by the plantar digital nerves, which provide sensory innervation to the toes.
Branches[edit | edit source]
Each common plantar digital artery divides into two proper plantar digital arteries. These branches supply the toes, providing oxygenated blood to the skin, muscles, and other tissues.
Function[edit | edit source]
The primary function of the common plantar digital arteries is to supply blood to the toes. This blood supply is essential for maintaining the health and function of the tissues in the toes, including the skin, muscles, and nerves.
Clinical Significance[edit | edit source]
The common plantar digital arteries can be involved in various medical conditions. For example, peripheral artery disease can lead to reduced blood flow in these arteries, causing symptoms such as pain and ulceration in the toes. Additionally, injuries to the foot can damage these arteries, leading to bleeding and ischemia.
