Pronunciation: [dˈɔːsə͡l vˈɛnəs ˈɑːt͡ʃ] (IPA)

The term "dorsal venous arch" refers to a group of veins found in the upper part of the foot. The correct spelling of this term is important to accurately communicate medical information. The phonetic transcription of the word is: /ˈdɔː.səl ˈviːnəs ɑːtʃ/, which breaks the word down into distinct syllables and sounds.

DORSAL VENOUS ARCH Meaning and Definition

1. The dorsal venous arch is a term in anatomy that refers to a network of veins found on the upper surface of the foot. It is located between the metatarsal bones and the tarsal bones, specifically the navicular and medial cuneiform bones. The arch is formed by the integration of smaller veins that arise from the plantar venous network of the foot.

   The dorsal venous arch functions as a major drainage system for the foot, carrying deoxygenated blood from the toes and the sole of the foot back towards the heart. From the arch, several veins emerge and transport the blood further up the leg. These veins, known as the dorsal digital veins, travel alongside the corresponding dorsal digital arteries and eventually join with the great saphenous vein or the small saphenous vein.

   The dorsal venous arch also serves an important role in temperature regulation. The numerous veins within the arch help to dissipate heat from the foot, thereby preventing overheating. Furthermore, the arch aids in keeping the blood supply to the foot constant and maintaining adequate perfusion.

   In summary, the dorsal venous arch is a network of veins located on the upper surface of the foot. It plays a crucial role in draining deoxygenated blood from the foot and maintaining temperature regulation.
