The spelling of the word "arteria metacarpea volaris" might seem daunting, but it can be broken down using IPA phonetic transcription. The pronunciation of each word is as follows: /ɑrtɛriə mɛtəkɑrpiə volɑris/. The "a" in "arteria" is pronounced like the "a" in "car", while "metacarpea" has the stress on the "ca" syllable. "Volaris" is pronounced with stress on the first syllable and a long "o" sound. With proper practice, the spelling of this medical term can become second nature.
The term "arteria metacarpea volaris" is a Latin expression referring to a blood vessel located in the hand, specifically in the palm region. More commonly known as the volar metacarpal artery, it is a branch of the deep palmar arch, which is responsible for supplying blood to the deep structures of the palm.
The volar metacarpal artery originates from the deep palmar arch, which itself is formed by the anastomosis (connection) between the radial artery and the ulnar artery. The deep palmar arch is situated deep within the palm, running along the metacarpal bones, which are the long bones of the hand.
The main function of the arteria metacarpea volaris is to deliver oxygenated blood to the structures in the palm of the hand, including the muscles, tendons, ligaments, and other soft tissues. This blood supply is crucial for maintaining the vitality and health of these structures, allowing them to perform their respective functions.
Injuries or pathologies that affect the arteria metacarpea volaris can have significant implications on the hand's overall function, potentially leading to compromised blood flow or ischemia (lack of blood supply) in the palm region. Proper identification and understanding of the arteria metacarpea volaris are essential for medical professionals, as it plays a vital role in hand anatomy and function.
Palmar interosseous, one of three arteries springing from the deep palmar arch and running in the three inner interosseous spaces; they anastomose with the metacarpeae dorsales.
