The spelling of the word "venae metacarpeae dorsales" may seem confusing at first, but it can be easily understood with the help of IPA phonetic transcription. In the word, "venae" is pronounced as "ˈviːni", "metacarpeae" as "ˌmɛtəˈkɑːpi", and "dorsales" as "ˈdɔːsəliːz". The correct spelling of this word is important for medical professionals because it refers to the dorsal veins of the hand. By using IPA transcription, we can pronounce this medical term with ease, ensuring effective communication between healthcare providers.
Venae metacarpeae dorsales refers to the dorsal metacarpal veins in the anatomical context. The term is derived from Latin, where "venae" stands for veins, "metacarpeae" refers to the metacarpal region of the hand, and "dorsales" indicates the dorsal aspect or the back side. In human anatomy, the metacarpals are the long bones located in the palm of the hand between the wrist and the fingers. These five bones form the framework of the hand and play a crucial role in hand movement and strength.
The venae metacarpeae dorsales are veins that are specifically present on the dorsal side or the back of the hand, running parallel to the metacarpal bones. These veins are responsible for draining deoxygenated blood from the hand and transporting it toward the heart for oxygenation. Like other veins, they have thin walls and contain valves that prevent the backflow of blood.
The venae metacarpeae dorsales are an important component of the hand's circulatory system. They serve as a network through which the hand's tissues and cells receive oxygen and nutrients, while waste products such as carbon dioxide and metabolic byproducts are removed. Their location on the dorsal side of the hand makes them relatively more accessible for medical procedures like blood sampling, intravenous therapy, or venipuncture.
Understanding the anatomical structures like the venae metacarpeae dorsales helps in various clinical and diagnostic procedures, as well as surgical interventions involving the hand or the upper limb.
Dorsal metacarpal veins, given off from the digital venous arches, from the dorsal venous rete of the hand, from which extend the cephalic and basilic veins.
