RADIAL ARTERIES Meaning and
Definition
-
Radial arteries are a pair of major arteries that play a crucial role in the circulatory system, specifically within the upper limbs. These arteries are named so because they originate from the radial bone of the forearm, one of the two bones that form the lower arm.
The radial arteries arise from the brachial artery as it passes the elbow joint, and they travel along the forearm, running parallel to the radius bone. They supply oxygenated blood, nutrients, and vital substances to the muscles, tissues, and organs of the forearm, hand, and fingers.
The radial arteries exhibit a characteristic branching pattern as they traverse the arm. These arteries give off several branches, such as the palmar carpal branch that supplies the palm of the hand, and the dorsal carpal branch that nourishes the back of the hand. Along their course, the radial arteries also give rise to superficial palmar arches and deep palmar arches, which provide anastomoses (interconnections) with the helper ulnar arteries, ensuring adequate blood supply throughout the upper limb.
The radial arteries are palpable at the wrist, allowing healthcare professionals to assess arterial characteristics such as pulse rate, strength, and quality. Due to their accessibility and proximity to the surface, the radial arteries are frequently used for various medical procedures, including arterial blood sampling and blood pressure measurement. Moreover, they serve as an important route for arterial access during interventional cardiac procedures like coronary angiography or percutaneous coronary intervention.

Etymology of RADIAL ARTERIES
The word "radial" in "radial arteries" comes from the Latin word "radius", meaning "spoke of a wheel" or "ray". It is derived from the Proto-Indo-European root "radi", which also gave rise to words like "ray", "radiate", and "radio". The term "radial" is used to describe anything that is arranged or extending in a straight line from a central point, resembling the spokes of a wheel. In the context of the human anatomy, the term refers to the radial artery, which is a major artery that extends from the brachial artery near the elbow to the wrist, forming a straight line along the radius bone of the forearm.
